═══════════════════════════════════════════════════════════════ 🎯 PROBLEM SOLVED: Collabora Server Warnings ═══════════════════════════════════════════════════════════════ Fixed two critical performance warnings in Collabora Online: 1. ❌ "Slow Kit jail setup with copying, cannot bind-mount" → Error: "coolmount: Operation not permitted" 2. ❌ "Your server is configured with insufficient hardware resources" → No performance tuning for 2-core CPX22 servers ═══════════════════════════════════════════════════════════════ ✅ SOLUTION IMPLEMENTED ═══════════════════════════════════════════════════════════════ Added Docker Capabilities: cap_add: - MKNOD # Create device nodes for bind-mounting - SYS_CHROOT # Use chroot for jail isolation Performance Tuning (optimized for 2 CPU cores): --o:num_prespawn_children=1 # Pre-spawn 1 child process --o:per_document.max_concurrency=2 # Max 2 threads per document (matches CPU cores) ═══════════════════════════════════════════════════════════════ 📊 IMPACT ═══════════════════════════════════════════════════════════════ BEFORE: ⚠️ "coolmount: Operation not permitted" (repeated errors) ⚠️ "Slow Kit jail setup with copying" ⚠️ "Insufficient hardware resources" ⚠️ Poor document editing performance AFTER: ✅ No more coolmount errors (bind-mount working) ✅ Faster jail initialization ✅ Optimized for 2-core servers ✅ Smooth document editing ℹ️ Minor systemplate warning remains (safe to ignore) ═══════════════════════════════════════════════════════════════ 🔄 DEPLOYMENT METHOD ═══════════════════════════════════════════════════════════════ Applied via live config update (NO data loss): 1. docker compose down 2. Update docker-compose.yml 3. docker compose up -d Downtime: ~30 seconds User Impact: Minimal (refresh page to reconnect) Data Safety: ✅ All data preserved ═══════════════════════════════════════════════════════════════ 📝 TECHNICAL DETAILS ═══════════════════════════════════════════════════════════════ Server Specs (CPX22): - CPU: 2 cores (detected with nproc) - RAM: 3.7GB total - Collabora limits: 1GB memory, 2 CPUs Configuration follows Collabora SDK recommendations: - per_document.max_concurrency ≤ CPU cores - num_prespawn_children = 1 (suitable for small deployments) Reference: https://sdk.collaboraonline.com/docs/installation/Configuration.html#performance ═══════════════════════════════════════════════════════════════ ✨ FUTURE DEPLOYMENTS ═══════════════════════════════════════════════════════════════ All new clients will automatically get optimized Collabora configuration. No rebuild required for config-only changes like this. ═══════════════════════════════════════════════════════════════ 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com> |
