+#### Recent Critical Issue Resolution (December 2024) 🔧
+
+**NFS Mount and Service Integration Issues - RESOLVED**
+
+1. **NFS Dataset Structure Resolution**:
+   - **Problem**: grey-area couldn't access media files via NFS mount
+   - **Root Cause**: ZFS dataset structure confusion - mounting `/mnt/storage` vs `/mnt/storage/media`
+   - **Solution**: Updated grey-area NFS mount from `sleeper-service:/mnt/storage` to `sleeper-service:/mnt/storage/media`
+   - **Result**: All media content now accessible (38 movies, 29 TV series, 9 music albums, 79 audiobooks)
+
+2. **NFS Network Export Configuration**:
+   - **Problem**: NFS exports only configured for local network (10.0.0.0/24)
+   - **Root Cause**: Missing Tailscale network access in NFS exports
+   - **Solution**: Updated sleeper-service NFS exports to include Tailscale network (100.64.0.0/10)
+   - **Result**: Reliable NFS connectivity over Tailscale mesh network
+
+3. **Conflicting tmpfiles Rules**:
+   - **Problem**: systemd tmpfiles creating conflicting directory structures for NFS exports
+   - **Root Cause**: tmpfiles.d rules interfering with ZFS dataset mounting
+   - **Solution**: Commented out conflicting tmpfiles rules in sleeper-service configuration
+   - **Result**: Clean NFS export structure without mounting conflicts
+
+4. **Forgejo Service Accessibility**:
+   - **Problem**: git.geokkjer.eu returning connection refused errors
+   - **Root Cause**: Multiple issues - firewall ports, hostname mapping, SSH forwarding
+   - **Solutions Applied**:
+     - Added port 3000 to grey-area firewall configuration
+     - Fixed reverse-proxy nginx configuration: `http://apps:3000` → `http://grey-area:3000`
+     - Updated SSH forwarding: `apps:22` → `grey-area:22` for port 1337
+   - **Result**: External access verified - `curl -I https://git.geokkjer.eu` returns HTTP/2 200
+
+5. **Hostname Resolution Consistency**:
+   - **Problem**: Inconsistent hostname references across configurations ("apps" vs "grey-area")
+   - **Root Cause**: Legacy hostname references in reverse-proxy configuration
+   - **Solution**: Updated all configurations to use consistent "grey-area" hostname
+   - **Result**: Proper service discovery and reverse proxy routing
+
+6. **User ID Consistency Challenge**:
+   - **Current State**: sma user has UID 1003 on grey-area vs 1001 on sleeper-service
+   - **Workaround**: NFS access working via group permissions (users group: GID 100)
+   - **Future Fix**: Implement centralized UID management across all machines
+
+#### Recent Troubleshooting & Solutions (June 2025):
+8. **NFS Dataset Structure**: Proper understanding of ZFS dataset hierarchy crucial for NFS exports
+   - `/mnt/storage` vs `/mnt/storage/media` dataset mounting differences
+   - NFS exports must match actual ZFS dataset structure, not subdirectories
+   - Client mount paths must align with server export paths for data access
+9. **Network Transition Management**: Tailscale vs local network connectivity during deployment
+   - NFS exports need both local (10.0.0.0/24) and Tailscale (100.64.0.0/10) network access
+   - extraHosts module provides consistent hostname resolution across network changes
+   - Firewall configuration must accommodate service ports for external access
+10. **Reverse Proxy Configuration**: Hostname consistency critical for proxy functionality  
+    - nginx upstream configuration must use correct hostnames (grey-area not apps)
+    - Service discovery relies on centralized hostname resolution modules
+    - SSL certificate management works seamlessly with proper nginx configuration
+11. **Service Integration**: Multi-machine service architecture requires coordinated configuration
+    - Forgejo deployment spans grey-area (service) + reverse-proxy (gateway) + DNS (domain)  
+    - NFS client/server coordination requires matching export/mount configurations
+    - User ID consistency across machines essential for NFS file access permissions
+12. **Firewall Management**: Service-specific port configuration essential for functionality
+    - Application servers need service ports opened (3000 for Forgejo, etc.)
+    - Reverse proxy needs external ports (80, 443, 1337) and internal connectivity  
+    - SSH access coordination between local and Tailscale networks for security
