# HMAC File Server Cluster Restart Guide
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
When HMAC File Server restarts in a distributed cluster environment, client applications on other VMs may need to be restarted or reconfigured to resume upload functionality. This guide addresses common scenarios and solutions.
|
|
||||||
|
|
||||||
## 🚨 **Common Client Restart Scenarios**
|
|
||||||
|
|
||||||
### 1. **XMPP Server Integration (XEP-0363)**
|
|
||||||
|
|
||||||
**Scenario:**
|
|
||||||
```
|
|
||||||
VM1: ejabberd/Prosody XMPP Server
|
|
||||||
VM2: HMAC File Server (restarted)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Why clients may need restart:**
|
|
||||||
- XMPP servers cache upload slot endpoints
|
|
||||||
- HTTP client connection pools become stale
|
|
||||||
- Upload session tokens may be invalidated
|
|
||||||
- DNS/service discovery cache issues
|
|
||||||
|
|
||||||
**Solutions:**
|
|
||||||
```bash
|
|
||||||
# On XMPP Server VM:
|
|
||||||
systemctl reload ejabberd # Reload config without full restart
|
|
||||||
# OR
|
|
||||||
systemctl restart ejabberd # Full restart if reload doesn't work
|
|
||||||
|
|
||||||
# For Prosody:
|
|
||||||
systemctl reload prosody
|
|
||||||
# OR
|
|
||||||
prosodyctl reload
|
|
||||||
```
|
|
||||||
|
|
||||||
### 2. **Application Servers with HTTP Clients**
|
|
||||||
|
|
||||||
**Scenario:**
|
|
||||||
```
|
|
||||||
VM1,VM2,VM3: Web Applications
|
|
||||||
VM4: HMAC File Server (restarted)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Why clients may need restart:**
|
|
||||||
- HTTP client libraries maintain connection pools
|
|
||||||
- Upload tokens cached in application memory
|
|
||||||
- Circuit breakers may be in "open" state
|
|
||||||
- Load balancer health checks failing
|
|
||||||
|
|
||||||
**Solutions:**
|
|
||||||
```bash
|
|
||||||
# Restart application servers:
|
|
||||||
systemctl restart your-app-server
|
|
||||||
|
|
||||||
# Or graceful reload if supported:
|
|
||||||
systemctl reload your-app-server
|
|
||||||
kill -USR1 $(pgrep -f your-app)
|
|
||||||
```
|
|
||||||
|
|
||||||
### 3. **Load Balancer / Proxy Issues**
|
|
||||||
|
|
||||||
**Scenario:**
|
|
||||||
```
|
|
||||||
VM1: nginx/haproxy Load Balancer
|
|
||||||
VM2: HMAC File Server (restarted)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Why restart needed:**
|
|
||||||
- Upstream connection pooling
|
|
||||||
- Health check failures
|
|
||||||
- Backend marking as "down"
|
|
||||||
|
|
||||||
**Solutions:**
|
|
||||||
```bash
|
|
||||||
# nginx:
|
|
||||||
nginx -s reload
|
|
||||||
|
|
||||||
# haproxy:
|
|
||||||
systemctl reload haproxy
|
|
||||||
# OR disable/enable backend:
|
|
||||||
echo "disable server hmac-backend/server1" | socat stdio /var/run/haproxy.sock
|
|
||||||
echo "enable server hmac-backend/server1" | socat stdio /var/run/haproxy.sock
|
|
||||||
```
|
|
||||||
|
|
||||||
## 🔧 **Enhanced Configuration for Cluster Resilience**
|
|
||||||
|
|
||||||
### Server-Level Settings
|
|
||||||
```toml
|
|
||||||
[server]
|
|
||||||
# Graceful shutdown to allow client reconnections
|
|
||||||
graceful_shutdown_timeout = "300s"
|
|
||||||
connection_drain_timeout = "120s"
|
|
||||||
restart_grace_period = "60s"
|
|
||||||
|
|
||||||
# Connection management
|
|
||||||
max_idle_conns_per_host = 5
|
|
||||||
idle_conn_timeout = "90s"
|
|
||||||
client_timeout = "300s"
|
|
||||||
```
|
|
||||||
|
|
||||||
### Upload Session Persistence
|
|
||||||
```toml
|
|
||||||
[uploads]
|
|
||||||
# Enable session persistence across restarts
|
|
||||||
session_persistence = true
|
|
||||||
session_recovery_timeout = "300s"
|
|
||||||
client_reconnect_window = "120s"
|
|
||||||
upload_slot_ttl = "3600s"
|
|
||||||
retry_failed_uploads = true
|
|
||||||
max_upload_retries = 3
|
|
||||||
```
|
|
||||||
|
|
||||||
### Redis-Based Session Sharing
|
|
||||||
```toml
|
|
||||||
[redis]
|
|
||||||
redisenabled = true
|
|
||||||
redisaddr = "redis-cluster:6379"
|
|
||||||
# Store upload sessions in Redis for cluster-wide persistence
|
|
||||||
redishealthcheckinterval = "30s"
|
|
||||||
```
|
|
||||||
|
|
||||||
## 🚀 **Automated Restart Coordination**
|
|
||||||
|
|
||||||
### 1. **Service Discovery Integration**
|
|
||||||
|
|
||||||
```bash
|
|
||||||
#!/bin/bash
|
|
||||||
# restart-coordination.sh
|
|
||||||
# Notify cluster components of HMAC server restart
|
|
||||||
|
|
||||||
HMAC_SERVER_VM="vm2"
|
|
||||||
XMPP_SERVERS=("vm1" "vm3")
|
|
||||||
APP_SERVERS=("vm4" "vm5" "vm6")
|
|
||||||
|
|
||||||
echo "HMAC File Server restart initiated on $HMAC_SERVER_VM"
|
|
||||||
|
|
||||||
# Wait for HMAC server to be ready
|
|
||||||
while ! curl -s http://$HMAC_SERVER_VM:8080/health > /dev/null; do
|
|
||||||
echo "Waiting for HMAC server to be ready..."
|
|
||||||
sleep 5
|
|
||||||
done
|
|
||||||
|
|
||||||
echo "HMAC server is ready. Notifying cluster components..."
|
|
||||||
|
|
||||||
# Restart XMPP servers
|
|
||||||
for server in "${XMPP_SERVERS[@]}"; do
|
|
||||||
echo "Reloading XMPP server on $server"
|
|
||||||
ssh $server "systemctl reload ejabberd || systemctl restart ejabberd"
|
|
||||||
done
|
|
||||||
|
|
||||||
# Restart application servers
|
|
||||||
for server in "${APP_SERVERS[@]}"; do
|
|
||||||
echo "Restarting application server on $server"
|
|
||||||
ssh $server "systemctl restart your-app-server"
|
|
||||||
done
|
|
||||||
|
|
||||||
echo "Cluster restart coordination completed"
|
|
||||||
```
|
|
||||||
|
|
||||||
### 2. **Health Check Integration**
|
|
||||||
|
|
||||||
```bash
|
|
||||||
#!/bin/bash
|
|
||||||
# hmac-health-check.sh
|
|
||||||
# Advanced health check that validates upload functionality
|
|
||||||
|
|
||||||
HMAC_URL="http://localhost:8080"
|
|
||||||
SECRET="f6g4ldPvQM7O2UTFeBEUUj33VrXypDAcsDt0yqKrLiOr5oQW"
|
|
||||||
|
|
||||||
# Test basic connectivity
|
|
||||||
if ! curl -s -f "$HMAC_URL/health" > /dev/null; then
|
|
||||||
echo "CRITICAL: HMAC server not responding"
|
|
||||||
exit 2
|
|
||||||
fi
|
|
||||||
|
|
||||||
# Test upload endpoint availability
|
|
||||||
HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" "$HMAC_URL/upload")
|
|
||||||
if [ "$HTTP_CODE" != "405" ] && [ "$HTTP_CODE" != "401" ]; then
|
|
||||||
echo "WARNING: Upload endpoint returning unexpected code: $HTTP_CODE"
|
|
||||||
exit 1
|
|
||||||
fi
|
|
||||||
|
|
||||||
echo "OK: HMAC File Server is healthy"
|
|
||||||
exit 0
|
|
||||||
```
|
|
||||||
|
|
||||||
### 3. **Consul/etcd Integration**
|
|
||||||
|
|
||||||
```bash
|
|
||||||
#!/bin/bash
|
|
||||||
# consul-hmac-restart.sh
|
|
||||||
# Integrate with Consul for service discovery
|
|
||||||
|
|
||||||
# Deregister service before restart
|
|
||||||
curl -X PUT "http://consul:8500/v1/agent/service/deregister/hmac-file-server"
|
|
||||||
|
|
||||||
# Restart HMAC server
|
|
||||||
systemctl restart hmac-file-server
|
|
||||||
|
|
||||||
# Wait for service to be ready
|
|
||||||
while ! ./hmac-health-check.sh; do
|
|
||||||
sleep 5
|
|
||||||
done
|
|
||||||
|
|
||||||
# Re-register service
|
|
||||||
curl -X PUT "http://consul:8500/v1/agent/service/register" \
|
|
||||||
-d '{
|
|
||||||
"ID": "hmac-file-server",
|
|
||||||
"Name": "hmac-file-server",
|
|
||||||
"Address": "vm2",
|
|
||||||
"Port": 8080,
|
|
||||||
"Check": {
|
|
||||||
"HTTP": "http://vm2:8080/health",
|
|
||||||
"Interval": "30s"
|
|
||||||
}
|
|
||||||
}'
|
|
||||||
|
|
||||||
# Trigger dependent service reloads via Consul watches
|
|
||||||
consul event -name="hmac-restarted" "HMAC File Server restarted on vm2"
|
|
||||||
```
|
|
||||||
|
|
||||||
## 🔍 **Troubleshooting Client Issues**
|
|
||||||
|
|
||||||
### Symptoms of Client Restart Needed:
|
|
||||||
- Upload requests returning "connection refused"
|
|
||||||
- Timeouts on upload attempts
|
|
||||||
- "Service temporarily unavailable" errors
|
|
||||||
- Cached upload slots returning 404/410
|
|
||||||
|
|
||||||
### Diagnosis Commands:
|
|
||||||
```bash
|
|
||||||
# Check client connection pools
|
|
||||||
ss -tuln | grep :8080
|
|
||||||
|
|
||||||
# Test upload endpoint from client VM
|
|
||||||
curl -I http://hmac-server:8080/upload
|
|
||||||
|
|
||||||
# Check client application logs
|
|
||||||
journalctl -u your-app-server -f
|
|
||||||
|
|
||||||
# Verify DNS resolution
|
|
||||||
nslookup hmac-server
|
|
||||||
dig hmac-server
|
|
||||||
```
|
|
||||||
|
|
||||||
### Quick Fixes:
|
|
||||||
```bash
|
|
||||||
# Clear client-side DNS cache
|
|
||||||
systemctl restart systemd-resolved
|
|
||||||
|
|
||||||
# Reset client HTTP connections
|
|
||||||
ss -K dst hmac-server
|
|
||||||
|
|
||||||
# Force application reconnection
|
|
||||||
systemctl restart your-app-server
|
|
||||||
```
|
|
||||||
|
|
||||||
## 🎯 **Best Practices for Production**
|
|
||||||
|
|
||||||
### 1. **Rolling Restarts**
|
|
||||||
- Use multiple HMAC server instances behind load balancer
|
|
||||||
- Restart one instance at a time
|
|
||||||
- Monitor client reconnection success
|
|
||||||
|
|
||||||
### 2. **Health Check Integration**
|
|
||||||
- Implement deep health checks that test upload functionality
|
|
||||||
- Use health check results in load balancer decisions
|
|
||||||
- Monitor client-side connection success rates
|
|
||||||
|
|
||||||
### 3. **Session Persistence**
|
|
||||||
- Use Redis cluster for session sharing
|
|
||||||
- Implement upload session recovery
|
|
||||||
- Provide client reconnection grace periods
|
|
||||||
|
|
||||||
### 4. **Monitoring and Alerts**
|
|
||||||
```bash
|
|
||||||
# Monitor upload success rates
|
|
||||||
watch -n 30 'curl -s http://hmac-server:9090/metrics | grep upload_success_total'
|
|
||||||
|
|
||||||
# Monitor client connections
|
|
||||||
watch -n 10 'ss -tuln | grep :8080 | wc -l'
|
|
||||||
|
|
||||||
# Monitor Redis session store
|
|
||||||
redis-cli info keyspace
|
|
||||||
```
|
|
||||||
|
|
||||||
## 📋 **Restart Checklist**
|
|
||||||
|
|
||||||
### Before HMAC Server Restart:
|
|
||||||
- [ ] Identify all client VMs and applications
|
|
||||||
- [ ] Verify Redis cluster health
|
|
||||||
- [ ] Check current upload queue status
|
|
||||||
- [ ] Notify operations team
|
|
||||||
|
|
||||||
### During Restart:
|
|
||||||
- [ ] Execute graceful shutdown
|
|
||||||
- [ ] Monitor client reconnection attempts
|
|
||||||
- [ ] Verify upload session recovery
|
|
||||||
- [ ] Check Redis session persistence
|
|
||||||
|
|
||||||
### After Restart:
|
|
||||||
- [ ] Restart/reload client applications as needed
|
|
||||||
- [ ] Verify upload functionality from all client VMs
|
|
||||||
- [ ] Monitor error rates and connection counts
|
|
||||||
- [ ] Update monitoring dashboards
|
|
||||||
|
|
||||||
### Client Applications to Restart:
|
|
||||||
- [ ] XMPP servers (ejabberd, Prosody)
|
|
||||||
- [ ] Web application servers
|
|
||||||
- [ ] API gateway services
|
|
||||||
- [ ] Load balancers (if upstream issues)
|
|
||||||
- [ ] Monitoring agents
|
|
||||||
|
|
||||||
This comprehensive approach ensures minimal disruption during HMAC File Server restarts in distributed environments.

# HMAC File Server 3.2 Installation Guide
|
|
||||||
|
|
||||||
## Quick Installation for XMPP Operators
|
|
||||||
|
|
||||||
The HMAC File Server includes an automated installer script designed specifically for XMPP operators who want to quickly deploy a file sharing service for their chat servers. The installer now supports both **native systemd installation** and **Docker deployment**.
|
|
||||||
|
|
||||||
### Prerequisites
|
|
||||||
|
|
||||||
- Linux system with systemd (Ubuntu 18.04+, CentOS 7+, Debian 9+, etc.) for native installation
|
|
||||||
- Docker and Docker Compose for containerized deployment
|
|
||||||
- Root or sudo access
|
|
||||||
- At least 1GB free disk space
|
|
||||||
- Internet connection for downloading dependencies
|
|
||||||
|
|
||||||
### Installation Options
|
|
||||||
|
|
||||||
The installer provides two deployment methods:
|
|
||||||
|
|
||||||
1. **Native Installation** (systemd service) - Traditional installation with Go build and systemd service
|
|
||||||
2. **Docker Deployment** (docker-compose) - Containerized deployment with automatic service orchestration
|
|
||||||
|
|
||||||
### Installation
|
|
||||||
|
|
||||||
1. **Download or clone the repository:**
|
|
||||||
```bash
|
|
||||||
git clone https://git.uuxo.net/uuxo/hmac-file-server.git
|
|
||||||
cd hmac-file-server
|
|
||||||
```
|
|
||||||
|
|
||||||
2. **Run the installer:**
|
|
||||||
```bash
|
|
||||||
sudo ./installer.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
3. **Choose deployment type:**
|

**Alternative: Pre-set secrets via environment variables:**
|
|
||||||
```bash
|
|
||||||
# For automation or if interactive input doesn't work
|
|
||||||
HMAC_SECRET='your-super-secret-hmac-key-here-minimum-32-characters' sudo -E ./installer.sh
|
|
||||||
|
|
||||||
# With both HMAC and JWT secrets
|
|
||||||
HMAC_SECRET='your-hmac-secret-32-chars-minimum' \
|
|
||||||
JWT_SECRET='your-jwt-secret-also-32-chars-minimum' \
|
|
||||||
sudo -E ./installer.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
3. **Follow the interactive prompts:**

```
|
|
||||||
|
|
||||||
#### For Docker Deployment
|
|
||||||
|
|
||||||
1. **Start the containers:**
|
|
||||||
```bash
|
|
||||||
cd /path/to/your/docker/deployment
|
|
||||||
./start.sh
|
|
||||||
# Or manually: docker-compose up -d
|
|
||||||
```
|
|
||||||
|
|
||||||
2. **Check status:**
|
|
||||||
```bash
|
|
||||||
docker-compose ps
|
|
||||||
```
|
|
||||||
|
|
||||||
3. **View logs:**
|
|
||||||
```bash
|
|
||||||
docker-compose logs -f hmac-file-server
|
|
||||||
```
|
|
||||||
|
|
||||||
4. **Stop the containers:**
|
|
||||||
```bash
|
|
||||||
./stop.sh
|
|
||||||
# Or manually: docker-compose down
|
|
||||||
```
|
|
||||||
|
|
||||||
### Firewall Configuration
|
|
||||||
|
|
||||||
4. **Configure firewall (required for both deployment types):**
|
|
||||||
```bash
|
|
||||||
# Example for ufw (Ubuntu/Debian)
|
|
||||||
sudo ufw allow 8080/tcp comment "HMAC File Server"
|
|
||||||
sudo ufw allow 9090/tcp comment "HMAC File Server Metrics"
|
|
||||||
|
|
||||||
# Example for firewalld (CentOS/RHEL/Fedora)
|
|
||||||
sudo firewall-cmd --permanent --add-port=8080/tcp
|
|
||||||
sudo firewall-cmd --permanent --add-port=9090/tcp
|
|
||||||
sudo firewall-cmd --reload
|
|
||||||
|
|
||||||
# Example for iptables (manual)
|
|
||||||
sudo iptables -A INPUT -p tcp --dport 8080 -j ACCEPT
|
|
||||||
sudo iptables -A INPUT -p tcp --dport 9090 -j ACCEPT
|
|
||||||
```
|
|
||||||
|
|
||||||
5. **Configure reverse proxy (recommended):**
|
|
||||||
```nginx
|
|
||||||
server {
|
|
||||||
listen 443 ssl http2;
|
|
||||||
server_name upload.yourdomain.com;
|
|
||||||
|
|
||||||
ssl_certificate /path/to/cert.pem;
|
|
||||||
ssl_certificate_key /path/to/key.pem;
|
|
||||||
|
|
||||||
location / {
|
|
||||||
proxy_pass http://localhost:8080;
|
|
||||||
proxy_set_header Host $host;
|
|
||||||
proxy_set_header X-Real-IP $remote_addr;
|
|
||||||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
||||||
proxy_set_header X-Forwarded-Proto $scheme;
|
|
||||||
|
|
||||||
# File upload settings
|
|
||||||
client_max_body_size 100M;
|
|
||||||
proxy_request_buffering off;
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### File Locations
|

|
|
||||||
- **Uploads**: `/var/lib/hmac-file-server/uploads/`
|
|
||||||
- **Logs**: `/var/log/hmac-file-server/hmac-file-server.log`
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
# Edit configuration
|
|
||||||
sudo nano /etc/hmac-file-server/config.toml
|
|
||||||
sudo systemctl reload hmac-file-server # Apply changes
|
|
||||||
```
|
|
||||||
|
|
||||||
### Uninstallation
|
|
||||||
|
|
||||||
The HMAC File Server installer includes a comprehensive uninstallation system with advanced data preservation options:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
sudo ./installer.sh --uninstall
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Safe Uninstallation Features
|
|
||||||
|
|
||||||
🔒 **Interactive Confirmation System**
|
|
||||||
- Multiple confirmation steps prevent accidental data loss
|
|
||||||
- Automatic detection of data directories from configuration
|
|
||||||
- Smart backup system with timestamped backups in `/var/backups/hmac-file-server-*`
|
|
||||||
- Detailed reporting showing file counts and directory sizes
|
|
||||||
|
|
||||||
#### Five Data Handling Options
|
|
||||||
|
|
||||||
**1. 🗑️ Complete Removal**
|
|
||||||
- Deletes all data including uploads, deduplication files, and logs
|
|
||||||
- Requires typing "DELETE" for final confirmation
|
|
||||||
- Provides comprehensive warning about permanent data loss
|
|
||||||
|
|
||||||
**2. 💾 Preserve Uploads and Deduplication**
|
|
||||||
- Preserves critical user files and deduplication data
|
|
||||||
- Removes logs (typically not needed for data recovery)
|
|
||||||
- Ideal for system migration or reinstallation
|
|
||||||
|
|
||||||
**3. 📋 Preserve All Data**
|
|
||||||
- Keeps uploads, deduplication data, and logs
|
|
||||||
- Comprehensive data preservation option
|
|
||||||
- Best for troubleshooting or temporary removal
|
|
||||||
|
|
||||||
**4. 🎯 Custom Selection**
|
|
||||||
- Interactive selection of which directories to preserve
|
|
||||||
- Shows detailed information for each directory before decision
|
|
||||||
- Allows granular control over data preservation
|
|
||||||
|
|
||||||
**5. ❌ Cancel Operation**
|
|
||||||
- Safely exits without making any changes
|
|
||||||
- No system modifications performed
|
|
||||||
|
|
||||||
#### What Gets Removed (Service Components)
|
|
||||||
- ✓ Systemd service (stopped and disabled)
|
|
||||||
- ✓ Installation directory (`/opt/hmac-file-server/`)
|
|
||||||
- ✓ Configuration files (`/etc/hmac-file-server/`)
|
|
||||||
- ✓ System user (`hmac-server`)
|
|
||||||
- ✓ Any remaining binaries
|
|
||||||
|
|
||||||
#### Data Backup Location
|
|
||||||
When data preservation is selected, files are moved to:
|
|
||||||
- `/var/backups/hmac-file-server-TIMESTAMP/`
|
|
||||||
- Timestamped directories for multiple backup versions
|
|
||||||
- Preserves original directory structure
|
|
||||||
|
|
||||||
**⚠️ Important**: The uninstaller provides multiple safety checks and data preservation options. Choose wisely based on your needs!
|
|
||||||
|
|
||||||
### Security Considerations
|
|
||||||
|
|
||||||
1. **Configure firewall properly** - Only allow necessary ports (8080, 9090) to authorized networks
|
|
||||||
2. **Use strong HMAC secrets** (minimum 32 characters, use random generators)
|
|
||||||
3. **Enable JWT authentication** for enhanced security
|
|
||||||
4. **Set up SSL/TLS** either directly or via reverse proxy
|
|
||||||
5. **Enable ClamAV** for virus scanning if handling untrusted files
|
|
||||||
6. **Regular backups** of configuration and uploaded files
|
|
||||||
7. **Monitor logs** for suspicious activity
|
|
||||||
8. **Restrict network access** - Consider limiting access to internal networks only
|
|
||||||
|
|
||||||
### Monitoring
|
|
||||||
|
|
||||||
The server provides Prometheus metrics at `/metrics` endpoint:
|
|
||||||
```bash
|
|
||||||
curl http://localhost:9090/metrics
|
|
||||||
```
|
|
||||||
|
|
||||||
Key metrics to monitor:
|
|
||||||
- `hmac_requests_total` - Total requests
|
|
||||||
- `hmac_upload_size_bytes` - Upload sizes
|
|
||||||
- `hmac_errors_total` - Error counts
|
|
||||||
- `hmac_active_connections` - Active connections
|
|
||||||
|
|
||||||
### Troubleshooting
|
|
||||||
|
|
||||||
#### Service won't start
|
|
||||||
1. Check logs: `sudo journalctl -u hmac-file-server -f`
|
|
||||||
2. Verify configuration: `sudo nano /etc/hmac-file-server/config.toml`
|
|
||||||
3. Check permissions on data directories
|
|
||||||
4. Ensure ports are not in use: `sudo netstat -tlnp | grep :8080`
|
|
||||||
|
|
||||||
#### High memory usage
|
|
||||||
1. Adjust worker settings in configuration
|
|
||||||
2. Enable Redis for session management
|
|
||||||
3. Check for large file uploads in progress
|
|
||||||
|
|
||||||
#### Files not uploading
|
|
||||||
1. Verify HMAC secret matches between XMPP server and file server
|
|
||||||
2. Check file size limits in configuration
|
|
||||||
3. Ensure sufficient disk space
|
|
||||||
4. Review ClamAV logs if virus scanning enabled
|
|
||||||
|
|
||||||

# Queue Resilience Configuration Guide
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
HMAC File Server 3.2 Ultimate Fixed includes advanced queue resilience features designed to handle timeout scenarios gracefully and maintain service availability under various network conditions.
|
|
||||||
|
|
||||||
## Enhanced Configuration Sections
|
|
||||||
|
|
||||||
### 1. Server-Level Timeout Resilience
|
|
||||||
|
|
||||||
```toml
|
|
||||||
[server]
|
|
||||||
# Enhanced timeout resilience settings
|
|
||||||
graceful_shutdown_timeout = "300s" # Time to wait for active uploads during shutdown
|
|
||||||
request_timeout = "7200s" # Maximum time for any single request (2 hours)
|
|
||||||
keep_alive_timeout = "300s" # HTTP keep-alive timeout
|
|
||||||
connection_drain_timeout = "180s" # Time to drain connections during shutdown
|
|
||||||
upload_stall_timeout = "600s" # Timeout if upload stalls (no data received)
|
|
||||||
download_stall_timeout = "300s" # Timeout if download stalls
|
|
||||||
retry_after_timeout = "60s" # Retry-After header when rejecting due to overload
|
|
||||||
max_concurrent_uploads = 100 # Maximum concurrent upload operations
|
|
||||||
upload_rate_limit = "10MB/s" # Per-connection upload rate limit
|
|
||||||
connection_pool_size = 200 # Maximum connection pool size
|
|
||||||
```
|
|
||||||
|
|
||||||
**Key Benefits:**
|
|
||||||
- **Graceful Degradation**: Server doesn't abruptly terminate active uploads during shutdown
|
|
||||||
- **Stall Detection**: Automatically detects and handles stalled uploads/downloads
|
|
||||||
- **Connection Management**: Limits concurrent operations to prevent resource exhaustion
|
|
||||||
- **Rate Limiting**: Prevents individual connections from overwhelming the server
|
|
||||||
|
|
||||||
### 2. Enhanced Worker Configuration
|
|
||||||
|
|
||||||
```toml
|
|
||||||
[workers]
|
|
||||||
# Enhanced queue robustness settings
|
|
||||||
queue_timeout = "300s" # Maximum time a job can wait in queue
|
|
||||||
queue_drain_timeout = "120s" # Time to wait for queue drain during shutdown
|
|
||||||
worker_health_check = "30s" # How often to check worker health
|
|
||||||
max_queue_retries = 3 # Max retries for failed queue operations
|
|
||||||
priority_queue_enabled = true # Enable priority queuing for different file sizes
|
|
||||||
large_file_queue_size = 20 # Separate queue for files > 100MB
|
|
||||||
small_file_queue_size = 100 # Queue for files < 10MB
|
|
||||||
queue_backpressure_threshold = 0.8 # Queue usage % to start backpressure
|
|
||||||
circuit_breaker_enabled = true # Enable circuit breaker for queue failures
|
|
||||||
circuit_breaker_threshold = 10 # Failures before opening circuit
|
|
||||||
circuit_breaker_timeout = "60s" # Time before retrying after circuit opens
|
|
||||||
```
|
|
||||||
|
|
||||||
**Key Benefits:**
|
|
||||||
- **Priority Queuing**: Large files don't block small file uploads
|
|
||||||
- **Health Monitoring**: Workers are continuously monitored for failures
|
|
||||||
- **Circuit Breaking**: Automatic failure detection and recovery
|
|
||||||
- **Backpressure Control**: Gradual slowdown instead of hard failures
|
|
||||||
|
|
||||||
### 3. Advanced Queue Resilience
|
|
||||||
|
|
||||||
```toml
|
|
||||||
[queue_resilience]
|
|
||||||
enabled = true
|
|
||||||
# Timeout handling
|
|
||||||
queue_operation_timeout = "30s" # Max time for queue operations
|
|
||||||
queue_full_behavior = "reject_oldest" # How to handle full queues
|
|
||||||
spillover_to_disk = true # Use disk when memory queue is full
|
|
||||||
spillover_directory = "/tmp/hmac-queue-spillover"
|
|
||||||
spillover_max_size = "1GB" # Max disk spillover size
|
|
||||||
|
|
||||||
# Queue persistence and recovery
|
|
||||||
persistent_queue = true # Persist queue state
|
|
||||||
queue_recovery_enabled = true # Recover queue state on restart
|
|
||||||
max_recovery_age = "24h" # Max age of items to recover
|
|
||||||
|
|
||||||
# Health monitoring
|
|
||||||
queue_health_check_interval = "15s" # Queue health check frequency
|
|
||||||
dead_letter_queue_enabled = true # Failed items queue
|
|
||||||
dead_letter_max_retries = 5 # Max retries before dead letter
|
|
||||||
dead_letter_retention = "7d" # Dead letter retention time
|
|
||||||
|
|
||||||
# Load balancing and prioritization
|
|
||||||
priority_levels = 3 # Number of priority levels
|
|
||||||
priority_aging_enabled = true # Age items to higher priority
|
|
||||||
priority_aging_threshold = "300s" # Time before aging up
|
|
||||||
load_balancing_strategy = "least_connections"
|
|
||||||
|
|
||||||
# Memory management
|
|
||||||
queue_memory_limit = "500MB" # Max memory for queues
|
|
||||||
queue_gc_interval = "60s" # Garbage collection interval
|
|
||||||
emergency_mode_threshold = 0.95 # Emergency mode trigger
|
|
||||||
```
|
|
||||||
|
|
||||||
**Key Benefits:**
|
|
||||||
- **Disk Spillover**: Never lose uploads due to memory constraints
|
|
||||||
- **Queue Recovery**: Resume operations after server restarts
|
|
||||||
- **Dead Letter Queuing**: Handle persistently failing uploads
|
|
||||||
- **Priority Aging**: Prevent starvation of lower-priority items
|
|
||||||
|
|
||||||
### 4. Comprehensive Timeout Configuration
|
|
||||||
|
|
||||||
```toml
|
|
||||||
[timeouts]
|
|
||||||
# Basic timeouts (existing)
|
|
||||||
readtimeout = "4800s"
|
|
||||||
writetimeout = "4800s"
|
|
||||||
idletimeout = "4800s"
|
|
||||||
|
|
||||||
# Enhanced timeout resilience
|
|
||||||
handshake_timeout = "30s" # TLS handshake timeout
|
|
||||||
header_timeout = "60s" # HTTP header read timeout
|
|
||||||
body_timeout = "7200s" # HTTP body read timeout
|
|
||||||
dial_timeout = "30s" # Connection dial timeout
|
|
||||||
keep_alive_probe_interval = "30s" # TCP keep-alive probe interval
|
|
||||||
keep_alive_probe_count = 9 # Keep-alive probes before giving up
|
|
||||||
|
|
||||||
# Adaptive timeouts based on file size
|
|
||||||
small_file_timeout = "60s" # Files < 10MB
|
|
||||||
medium_file_timeout = "600s" # Files 10MB-100MB
|
|
||||||
large_file_timeout = "3600s" # Files 100MB-1GB
|
|
||||||
huge_file_timeout = "7200s" # Files > 1GB
|
|
||||||
|
|
||||||
# Retry and backoff settings
|
|
||||||
retry_base_delay = "1s" # Base delay between retries
|
|
||||||
retry_max_delay = "60s" # Maximum delay between retries
|
|
||||||
retry_multiplier = 2.0 # Exponential backoff multiplier
|
|
||||||
max_retry_attempts = 5 # Maximum retry attempts
|
|
||||||
```
|
|
||||||
|
|
||||||
**Key Benefits:**
|
|
||||||
- **Adaptive Timeouts**: Different timeouts based on file size
|
|
||||||
- **Connection Resilience**: TCP keep-alive prevents silent failures
|
|
||||||
- **Exponential Backoff**: Intelligent retry timing reduces server load
|
|
||||||
- **Granular Control**: Fine-tuned timeouts for different operations
|
|
||||||
|
|
||||||
## Timeout Scenario Handling
|
|
||||||
|
|
||||||
### 1. Network Interruption Scenarios
|
|
||||||
|
|
||||||
**Mobile Network Switching:**
|
|
||||||
- Keep-alive probes detect network changes
|
|
||||||
- Chunked uploads can resume after network restoration
|
|
||||||
- Upload sessions persist through network interruptions
|
|
||||||
|
|
||||||
**Slow Network Conditions:**
|
|
||||||
- Adaptive timeouts prevent premature termination
|
|
||||||
- Rate limiting prevents network saturation
|
|
||||||
- Progress monitoring detects actual stalls vs. slow transfers
|
|
||||||
|
|
||||||
### 2. Server Overload Scenarios
|
|
||||||
|
|
||||||
**High Load Conditions:**
|
|
||||||
- Circuit breaker prevents cascade failures
|
|
||||||
- Backpressure slows down new requests gracefully
|
|
||||||
- Priority queuing ensures critical uploads continue
|
|
||||||
|
|
||||||
**Memory Pressure:**
|
|
||||||
- Disk spillover prevents memory exhaustion
|
|
||||||
- Queue garbage collection manages memory usage
|
|
||||||
- Emergency mode provides last-resort protection
|
|
||||||
|
|
||||||
### 3. Application Restart Scenarios
|
|
||||||
|
|
||||||
**Graceful Shutdown:**
|
|
||||||
- Active uploads get time to complete
|
|
||||||
- Queue state is persisted before shutdown
|
|
||||||
- Connections are drained properly
|
|
||||||
|
|
||||||
**Recovery After Restart:**
|
|
||||||
- Queue state is restored from persistence
|
|
||||||
- Upload sessions are recovered
|
|
||||||
- Dead letter items are reprocessed
|
|
||||||
|
|
||||||
## Monitoring and Observability
|
|
||||||
|
|
||||||
### Queue Health Metrics
|
|
||||||
|
|
||||||
The enhanced configuration provides comprehensive metrics:
|
|
||||||
|
|
||||||
- **Queue Length**: Current items in each queue
|
|
||||||
- **Queue Processing Time**: Time items spend in queue
|
|
||||||
- **Worker Health**: Individual worker status and performance
|
|
||||||
- **Circuit Breaker State**: Open/closed status and failure counts
|
|
||||||
- **Spillover Usage**: Disk spillover utilization
|
|
||||||
- **Dead Letter Queue**: Failed item counts and reasons
|

|
||||||
|
|
||||||
Enhanced logging provides visibility into queue operations:
|
|
||||||
|
|
||||||
```
|
|
||||||
INFO: Queue backpressure activated (80% full)
|
|
||||||
WARN: Circuit breaker opened for upload queue (10 consecutive failures)
|
|
||||||
INFO: Spillover activated: 50MB written to disk
|
|
||||||
ERROR: Dead letter queue: Upload failed after 5 retries
|
|
||||||
INFO: Queue recovery: Restored 23 items from persistence
|
|
||||||
```
|
|
||||||
|
|
||||||
## Best Practices
|
|
||||||
|
|
||||||
### 1. Configuration Tuning
|
|
||||||
|
|
||||||
**For High-Volume Servers:**
|
|
||||||
```toml
|
|
||||||
uploadqueuesize = 200
|
|
||||||
large_file_queue_size = 50
|
|
||||||
small_file_queue_size = 500
|
|
||||||
max_concurrent_uploads = 200
|
|
||||||
queue_memory_limit = "1GB"
|
|
||||||
```
|
|
||||||
|
|
||||||
**For Memory-Constrained Environments:**
|
|
||||||
```toml
|
|
||||||
uploadqueuesize = 50
|
|
||||||
spillover_to_disk = true
|
|
||||||
queue_memory_limit = "200MB"
|
|
||||||
emergency_mode_threshold = 0.85
|
|
||||||
```
|
|
||||||
|
|
||||||
**For Mobile/Unreliable Networks:**
|
|
||||||
```toml
|
|
||||||
keep_alive_probe_interval = "15s"
|
|
||||||
upload_stall_timeout = "300s"
|
|
||||||
max_retry_attempts = 8
|
|
||||||
retry_max_delay = "120s"
|
|
||||||
```
|
|
||||||
|
|
||||||
### 2. Monitoring Setup
|
|
||||||
|
|
||||||
**Essential Metrics to Monitor:**
|
|
||||||
- Queue length trends
|
|
||||||
- Worker health status
|
|
||||||
- Circuit breaker activations
|
|
||||||
- Spillover usage
|
|
||||||
- Dead letter queue growth
|
|
||||||
|
|
||||||
**Alert Thresholds:**
|
|
||||||
- Queue length > 80% capacity
|
|
||||||
- Circuit breaker open for > 5 minutes
|
|
||||||
- Dead letter queue growth > 10 items/hour
|
|
||||||
- Spillover usage > 50% of limit
|
|
||||||
|
|
||||||
### 3. Troubleshooting
|
|
||||||
|
|
||||||
**Common Issues and Solutions:**
|
|
||||||
|
|
||||||
**Frequent Timeouts:**
|
|
||||||
- Check network stability
|
|
||||||
- Increase adaptive timeouts for file size
|
|
||||||
- Enable more aggressive keep-alive settings
|
|
||||||
|
|
||||||
**Queue Backlogs:**
|
|
||||||
- Monitor worker health
|
|
||||||
- Check for resource constraints
|
|
||||||
- Consider increasing worker count
|
|
||||||
|
|
||||||
**Memory Issues:**
|
|
||||||
- Enable disk spillover
|
|
||||||
- Reduce queue memory limit
|
|
||||||
- Increase garbage collection frequency
|
|
||||||
|
|
||||||
## Implementation Notes
|
|
||||||
|
|
||||||
The enhanced queue resilience features are designed to be:
|
|
||||||
|
|

# HMAC File Server Queue Resilience Enhancement Summary
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
I've reviewed and enhanced the queuing system in HMAC File Server 3.2 Ultimate Fixed to make it significantly more robust in handling timeout scenarios. The improvements span multiple layers: configuration, queue management, worker health, and failure recovery.
|
|
||||||
|
|
||||||
## Key Problems Addressed
|
|
||||||
|
|
||||||
### 1. **Timeout-Related Queue Failures**
|
|
||||||
- **Problem**: Queued uploads timing out during network interruptions
|
|
||||||
- **Solution**: Adaptive timeouts based on file size, keep-alive monitoring, and resumable uploads
|
|
||||||
|
|
||||||
### 2. **Queue Overflow During High Load**
|
|
||||||
- **Problem**: Memory queues filling up and rejecting new uploads
|
|
||||||
- **Solution**: Disk spillover, priority queuing, and backpressure control
|
|
||||||
|
|
||||||
### 3. **Worker Health and Failure Detection**
|
|
||||||
- **Problem**: Failed workers blocking queue processing
|
|
||||||
- **Solution**: Continuous health monitoring, circuit breakers, and automatic recovery
|
|
||||||
|
|
||||||
### 4. **Network Interruption Recovery**
|
|
||||||
- **Problem**: Lost uploads during network switching or disconnections
|
|
||||||
- **Solution**: Persistent queue state, upload session recovery, and graceful degradation
|
|
||||||
|
|
||||||
## Enhanced Configuration Structure
|
|
||||||
|
|
||||||
### Server-Level Resilience (`[server]` section)
|
|
||||||
```toml
|
|
||||||
# NEW: Advanced timeout handling
|
|
||||||
graceful_shutdown_timeout = "300s" # Complete active uploads before shutdown
|
|
||||||
request_timeout = "7200s" # 2-hour maximum for large files
|
|
||||||
upload_stall_timeout = "600s" # Detect stalled uploads
|
|
||||||
max_concurrent_uploads = 100 # Prevent resource exhaustion
|
|
||||||
connection_pool_size = 200 # Manage connection resources
|
|
||||||
```
|
|
||||||
|
|
||||||
### Enhanced Worker Management (`[workers]` section)
|
|
||||||
```toml
|
|
||||||
# NEW: Queue robustness features
|
|
||||||
queue_timeout = "300s" # Max queue wait time
|
|
||||||
priority_queue_enabled = true # Separate queues by file size
|
|
||||||
large_file_queue_size = 20 # Dedicated large file queue
|
|
||||||
circuit_breaker_enabled = true # Automatic failure detection
|
|
||||||
queue_backpressure_threshold = 0.8 # Gradual slowdown vs hard rejection
|
|
||||||
```
|
|
||||||
|
|
||||||
### Advanced Queue Resilience (`[queue_resilience]` section - NEW)
|
|
||||||
```toml
|
|
||||||
# Spillover and persistence
|
|
||||||
spillover_to_disk = true # Use disk when memory is full
|
|
||||||
persistent_queue = true # Survive server restarts
|
|
||||||
queue_recovery_enabled = true # Restore queue state after restart
|
|
||||||
|
|
||||||
# Health monitoring
|
|
||||||
dead_letter_queue_enabled = true # Handle persistently failing uploads
|
|
||||||
queue_health_check_interval = "15s" # Continuous monitoring
|
|
||||||
emergency_mode_threshold = 0.95 # Last-resort protection
|
|
||||||
|
|
||||||
# Priority management
|
|
||||||
priority_levels = 3 # High/Medium/Low priority queues
|
|
||||||
priority_aging_enabled = true # Prevent starvation
|
|
||||||
load_balancing_strategy = "least_connections"
|
|
||||||
```
|
|
||||||
|
|
||||||
### Comprehensive Timeout Configuration (`[timeouts]` section)
|
|
||||||
```toml
|
|
||||||
# NEW: Adaptive timeouts by file size
|
|
||||||
small_file_timeout = "60s" # < 10MB files
|
|
||||||
medium_file_timeout = "600s" # 10MB-100MB files
|
|
||||||
large_file_timeout = "3600s" # 100MB-1GB files
|
|
||||||
huge_file_timeout = "7200s" # > 1GB files
|
|
||||||
|
|
||||||
# NEW: Connection resilience
|
|
||||||
keep_alive_probe_interval = "30s" # Detect network issues
|
|
||||||
keep_alive_probe_count = 9 # Retries before giving up
|
|
||||||
|
|
||||||
# NEW: Intelligent retry logic
|
|
||||||
retry_base_delay = "1s" # Exponential backoff starting point
|
|
||||||
retry_max_delay = "60s" # Maximum backoff delay
|
|
||||||
max_retry_attempts = 5 # Retry limit
|
|
||||||
```
|
|
||||||
|
|
||||||
## Core Resilience Features
|
|
||||||
|
|
||||||
### 1. **Multi-Tier Queue Architecture**
|
|
||||||
- **High Priority Queue**: Small files, urgent uploads
|
|
||||||
- **Medium Priority Queue**: Regular uploads
|
|
||||||
- **Low Priority Queue**: Large files, background uploads
|
|
||||||
- **Disk Spillover**: Unlimited capacity fallback
|
|
||||||
- **Dead Letter Queue**: Failed uploads for manual intervention
|
|
||||||
|
|
||||||
### 2. **Intelligent Timeout Management**
|
|
||||||
- **Adaptive Timeouts**: Different limits based on file size
|
|
||||||
- **Progress Monitoring**: Distinguish between slow and stalled transfers
|
|
||||||
- **Keep-Alive Probing**: Early detection of network issues
|
|
||||||
- **Graceful Degradation**: Slow down rather than fail hard
|
|
||||||
|
|
||||||
### 3. **Circuit Breaker Pattern**
|
|
||||||
- **Failure Detection**: Automatic detection of systemic issues
|
|
||||||
- **Fail-Fast**: Prevent cascade failures during outages
|
|
||||||
- **Auto-Recovery**: Intelligent retry after issues resolve
|
|
||||||
- **Metrics Integration**: Observable failure patterns
|
|
||||||
|
|
||||||
### 4. **Worker Health Monitoring**
|
|
||||||
- **Continuous Monitoring**: Regular health checks for all workers
|
|
||||||
- **Performance Tracking**: Average processing time and error rates
|
|
||||||
- **Automatic Recovery**: Restart failed workers automatically
|
|
||||||
- **Load Balancing**: Route work to healthiest workers
|
|
||||||
|
|
||||||
### 5. **Queue Persistence and Recovery**
|
|
||||||
- **State Persistence**: Queue contents survive server restarts
|
|
||||||
- **Session Recovery**: Resume interrupted uploads automatically
|
|
||||||
- **Redis Integration**: Distributed queue state for clustering
|
|
||||||
- **Disk Fallback**: Local persistence when Redis unavailable
|
|
||||||
|
|
||||||
## Timeout Scenario Handling
|
|
||||||
|
|
||||||
### Network Interruption Recovery
|
|
||||||
```
|
|
||||||
User uploads 1GB file → Network switches from WiFi to 4G
|
|
||||||
├── Upload session persisted to Redis/disk
|
|
||||||
├── Keep-alive probes detect network change
|
|
||||||
├── Upload pauses gracefully (no data loss)
|
|
||||||
├── Network restored after 30 seconds
|
|
||||||
├── Upload session recovered from persistence
|
|
||||||
└── Upload resumes from last completed chunk
|
|
||||||
```
|
|
||||||
|
|
||||||
### Server Overload Protection
|
|
||||||
```
|
|
||||||
100 concurrent uploads overwhelm server
|
|
||||||
├── Queue reaches 80% capacity (backpressure threshold)
|
|
||||||
├── New uploads get delayed (not rejected)
|
|
||||||
├── Circuit breaker monitors failure rate
|
|
||||||
├── Large files moved to disk spillover
|
|
||||||
├── Priority queue ensures small files continue
|
|
||||||
└── System degrades gracefully under load
|
|
||||||
```
|
|
||||||
|
|
||||||
### Application Restart Robustness
|
|
||||||
```
|
|
||||||
Server restart during active uploads
|
|
||||||
├── Graceful shutdown waits 300s for completion
|
|
||||||
├── Active upload sessions persisted to disk
|
|
||||||
├── Queue state saved to Redis/disk
|
|
||||||
├── Server restarts with new configuration
|
|
||||||
├── Queue state restored from persistence
|
|
||||||
├── Upload sessions recovered automatically
|
|
||||||
└── Clients resume uploads seamlessly
|
|
||||||
```
|
|
||||||
|
|
||||||
## Performance Impact
|
|
||||||
|
|
||||||
### Memory Usage
|
|
||||||
- **Queue Memory Limit**: Configurable cap on queue memory usage
|
|
||||||
- **Spillover Efficiency**: Only activates when memory queues full
|
|
||||||
- **Garbage Collection**: Regular cleanup of expired items
|
|
||||||
|
|
||||||
### CPU Overhead
|
|
||||||
- **Health Monitoring**: Lightweight checks every 15-30 seconds
|
|
||||||
- **Circuit Breaker**: O(1) operations with atomic counters
|
|
||||||
- **Priority Aging**: Batched operations to minimize impact
|
|
||||||
|
|
||||||
### Disk I/O
|
|
||||||
- **Spillover Optimization**: Sequential writes, batch operations
|
|
||||||
- **Persistence Strategy**: Asynchronous writes, configurable intervals
|
|
||||||
- **Recovery Efficiency**: Parallel restoration of queue state
|
|
||||||
|
|
||||||
