Storage Strategy Analysis for Your Infrastructure
Generated: 2025-08-29
Status: DECISION NEEDED - RECOMMENDATION PROVIDED

---

🎯 EXECUTIVE SUMMARY

🔄 SMB vs NFS COMPARISON

SMB Advantages (For Your Homelab)

✅ Already Working: 15 shares active, 2 devices connected
✅ Simpler Setup: No complex export configuration needed
✅ Better Reliability: Less prone to network issues
✅ Guest Access: Easy file sharing for personal use
✅ Windows Compatible: Works with all your devices
✅ Performance: Direct mergerfs access (good speed)
✅ Less Maintenance: Fewer moving parts to break

NFS Advantages (For Docker)

✅ Docker Native: Better integration with containers
✅ Unix Permissions: Preserves file ownership/perms
✅ Network Efficiency: Lower overhead for many small files
✅ Locking: Better file locking for databases
✅ Scalability: Better for many concurrent users

SMB Disadvantages

❌ Docker Integration: Requires extra configuration
❌ File Locking: Less reliable for databases
❌ Performance: Higher overhead for many small files
❌ Permissions: Windows-style permissions

NFS Disadvantages

❌ Complexity: More configuration required
❌ Reliability: More prone to network issues
❌ Troubleshooting: Harder to debug problems
❌ Setup Time: Requires OMV web interface configuration

🎯 RECOMMENDED STRATEGY

For Your 1-3 User Homelab:

Use SMB For:

• User Data Access: Photos, documents, media files
• Backup Storage: System backups and snapshots
• File Sharing: Direct access from Windows/Linux/Mac
• Media Libraries: Movies, TV shows, music
• Personal Files: Documents, pictures, vault data

Use NFS For:

• Docker Services: Only services that specifically require NFS
• Database Storage: PostgreSQL, MariaDB data directories
• Configuration Files: Service configs that need Unix permissions
• High-Performance Apps: Services with many small file operations

Specific Service Recommendations:

Service	Recommended Storage	Reason
Jellyfin	SMB	Media files, simple access
Immich	SMB	Photo storage, user access
Nextcloud	SMB	File sharing, user access
Home Assistant	NFS	Configuration, database
Paperless-NGX	NFS	Document database
Gitea	NFS	Git repositories, permissions
Vaultwarden	NFS	Database, security
AdGuard	NFS	Configuration files
Caddy	NFS	SSL certificates, config

🚀 IMPLEMENTATION PLAN

Option A: SMB-First Approach (RECOMMENDED)

# 1. Keep all existing SMB shares
# 2. Use SMB for user data and media
# 3. Only configure NFS for services that require it
# 4. Simplify migration by reducing complexity

Benefits:

• Faster migration (less configuration)
• More reliable (fewer moving parts)
• Easier troubleshooting
• Better user experience

Option B: NFS-First Approach

# 1. Configure all NFS exports via OMV web interface
# 2. Migrate all services to use NFS
# 3. Keep SMB for user file access only
# 4. More complex but "proper" Docker setup

Benefits:

• "Proper" Docker architecture
• Better for future scaling
• More enterprise-like setup

📋 DECISION MATRIX

For Your Use Case (1-3 users, personal homelab):

Factor	SMB	NFS	Winner
Setup Complexity	Low	High	SMB
Reliability	High	Medium	SMB
Performance	Good	Better	NFS
Troubleshooting	Easy	Hard	SMB
User Experience	Great	Good	SMB
Docker Integration	Fair	Excellent	NFS
Maintenance	Low	High	SMB
Future-Proofing	Fair	Excellent	NFS

Overall Winner: SMB (6-2 score for your use case)

🎯 FINAL RECOMMENDATION

Hybrid Approach (Best of Both Worlds):

1. Keep SMB as Primary Storage:

   • Use existing 15 SMB shares for user data
   • No additional configuration needed
   • Reliable and simple

2. Use NFS Only Where Required:

   • Home Assistant configuration
   • Database storage (PostgreSQL, MariaDB)
   • Services with specific NFS requirements

3. Migration Strategy:

   • Start with SMB for everything
   • Only add NFS exports for services that fail
   • Keep it simple and reliable

Immediate Actions:

# 1. Test Docker services with SMB first
# 2. Only configure NFS for services that require it
# 3. Focus on getting services working, not perfect architecture
# 4. Optimize later if needed

---

✅ CONCLUSION

For your 1-3 user homelab, SMB is the better choice. It's simpler, more reliable, and already working. You can always add NFS later for specific services that need it.

Recommendation: Start with SMB, add NFS only where required.

Migration Impact: Positive - simpler, faster, more reliable migration.
