Proxmox VE Comprehensive Configuration Review

Historical note: This review documents an early cluster state when many workloads were still concentrated on older hosts. It is useful for migration history, not for current placement decisions. For the live estate, use docs/04-configuration/ALL_VMIDS_ENDPOINTS.md, docs/02-architecture/DBIS_NODE_ROLE_MATRIX.md, and config/proxmox-operational-template.json.

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
