Executive Summary

✅ Completed Tasks

• Hostname migration (pve → r630-01, pve2 → r630-02)
• IP address audit (no conflicts found)
• Proxmox services verified (all operational)
• Storage configuration reviewed

⚠️ Issues Identified

• r630-01 and r630-02 have LVM thin storage disabled
• All VMs/containers currently on ml110 only
• Storage not optimized for performance on r630-01/r630-02

---

Hostname Migration - COMPLETE ✅

Status

Storage Issues

r630-01 Storage Issue

Problem: LVM thin pools exist (data 200GB, thin1 208GB) but Proxmox storage is disabled

Root Cause: Storage configured in Proxmox but not activated/enabled

Solution:

# Update storage.cfg node references on r630-01
ssh root@192.168.11.11
# Update node references from "pve" to "r630-01"
sed -i 's/nodes pve$/nodes r630-01/' /etc/pve/storage.cfg
sed -i 's/nodes pve /nodes r630-01 /' /etc/pve/storage.cfg
# Enable storage
pvesm set local-lvm --disable 0 2>/dev/null || true
pvesm set thin1 --disable 0 2>/dev/null || true

r630-02 Storage Issue

Problem: Storage disabled, LVM configuration unknown

Solution:

# Update storage.cfg node references on r630-02
ssh root@192.168.11.12
# Update node references from "pve2" to "r630-02"
sed -i 's/nodes pve2$/nodes r630-02/' /etc/pve/storage.cfg
sed -i 's/nodes pve2 /nodes r630-02 /' /etc/pve/storage.cfg
# Enable all thin storage pools
for storage in thin1 thin2 thin3 thin4 thin5 thin6; do
    pvesm set "$storage" --disable 0 2>/dev/null || true
done

Critical Recommendations

1. Enable LVM Thin Storage on r630-01 and r630-02 🔴 CRITICAL

Priority: HIGH
Impact: Cannot migrate VMs or create new VMs with optimal storage

Action Required:

1. Enable local-lvm storage on both hosts
2. Activate thin1 storage pools if they exist
3. Verify storage is accessible and working

Script Available: scripts/enable-local-lvm-storage.sh (may need updates)

2. Distribute VMs Across Hosts ⚠️ RECOMMENDED

Current State: All 34 VMs on ml110 (overloaded)

Recommendation:

• Migrate some VMs to r630-01 and r630-02
• Balance workload across all three hosts
• Use r630-01/r630-02 for new deployments

Benefits:

• Better resource utilization
• Improved performance (ml110 CPU is slower)
• Better redundancy

3. Update Cluster Configuration ⚠️ RECOMMENDED

Issue: Hostnames changed but cluster may still reference old names

Action:

# Check cluster configuration
pvecm status
pvecm nodes

# Update if needed (may require cluster reconfiguration)

4. Storage Performance Optimization ⚠️ RECOMMENDED

Current:

• ml110: Using local-lvm (good)
• r630-01: Only local (directory) available (slower)
• r630-02: Only local (directory) available (slower)

Recommendation:

• Enable LVM thin storage on r630-01/r630-02 for better performance
• Use thin provisioning for space efficiency
• Monitor storage usage

5. Resource Monitoring ⚠️ RECOMMENDED

ml110:

• Memory usage: 75% (high) - Monitor closely
• CPU: Older/slower - Consider workload reduction

r630-01/r630-02:

• Excellent resources available
• Ready for heavy workloads

Next Steps

Immediate (Before Starting VMs)

1. Enable Storage on r630-01:

   ssh root@192.168.11.11
   # Check current storage config
   cat /etc/pve/storage.cfg
   # Enable local-lvm
   pvesm set local-lvm --disable 0
   # Or reconfigure if needed
   

2. Configure Storage on r630-02:

   ssh root@192.168.11.12
   # Check LVM setup
   vgs
   lvs
   # Configure appropriate storage
   

3. Verify Storage:

   # On each host
   pvesm status
   # Should show local-lvm as active
   

After Storage is Enabled

1. Test VM Creation:

   • Create test container on r630-01
   • Create test container on r630-02
   • Verify storage works correctly

2. Start VMs:

   • All IPs verified, no conflicts
