r630-01 Migration Complete - VMIDs 100-130 and 7800-7811

Date: 2025-01-20
Status: ✅ Migration Complete
Method: Backup/Restore using --dumpdir (bypasses storage config issue)

Executive Summary

Successfully migrated 12 containers from r630-02 to r630-01 using backup/restore method with --dumpdir parameter:

VMIDs 100-130 (7 containers) → thin1 storage (96 GB)
VMIDs 7800-7811 (5 containers) → local storage (210 GB)
Total: 306 GB migrated

Blocking Issue Resolution

Problem

Storage configuration mismatch: thin1 storage config said vgname pve but r630-02's thin1 uses VG thin1
vzdump failed with "no such logical volume pve/thin1"

Solution

Used vzdump --dumpdir parameter to bypass storage configuration dependency
This allows vzdump to work directly with volume paths without relying on storage config
Backup/restore process completed successfully

Migration Details

VMs Migrated

VMIDs 100-130 → thin1 storage:

✅ 100: proxmox-mail-gateway
✅ 101: proxmox-datacenter-manager
✅ 102: cloudflared
✅ 103: omada
✅ 104: gitea
✅ 105: nginxproxymanager
✅ 130: monitoring-1

VMIDs 7800-7811 → local storage:

✅ 7800: sankofa-api-1
✅ 7801: sankofa-portal-1
✅ 7802: sankofa-keycloak-1
✅ 7810: mim-web-1
✅ 7811: mim-api-1

Migration Method

Backup/Restore with --dumpdir

Used vzdump --dumpdir to bypass storage configuration issues:

# Backup (bypasses storage config)
vzdump <vmid> --dumpdir /var/lib/vz/dump --compress gzip --mode stop

# Restore
pct restore <vmid> /var/lib/vz/dump/vzdump-lxc-<vmid>-*.tar.gz \
    --storage <target-storage> \
    --target r630-01

# Cleanup
pct destroy <vmid>  # on source node

Key Improvement: Using --dumpdir instead of --storage allows vzdump to work even when storage configuration doesn't match actual volume groups.

Storage Distribution

r630-01 Storage Usage

Storage	Type	Used	Available	VMs
thin1	lvmthin	96 GB	112 GB	VMIDs 100-130
local	dir	210 GB	326 GB	VMIDs 7800-7811
Total		306 GB	438 GB	12 containers

Verification

Pre-Migration

✅ All 12 VMs verified on r630-02
✅ Storage capacity confirmed (944 GB available)
✅ All VMs in stopped state
✅ Blocking issue resolved (using --dumpdir)

Post-Migration

✅ All 12 VMs verified on r630-01
✅ No VMs remaining on r630-02 for these VMIDs
✅ Storage usage confirmed
✅ VMs configured correctly

Migration Script

Script: scripts/migrate-vms-fixed.sh

Key Features:

Uses --dumpdir to bypass storage config issues
Automated backup/restore for all VMs
Error handling and verification
Progress reporting
Automatic cleanup

Key Learnings

--dumpdir Parameter: Bypasses storage configuration dependency in vzdump
Storage Config Issues: Can be worked around using direct dump directory
Backup/Restore Reliability: Most reliable method when storage configurations don't match
Storage Conversion: Proxmox automatically converts storage types during restore

Next Steps Completed

✅ Fixed blocking issue (using --dumpdir)
✅ Migrated all VMs
✅ Verified migrations
✅ Updated documentation

Next Steps (Optional)

⏳ Verify VM functionality - Start VMs and verify services
⏳ Monitor storage usage - Track thin1 and local storage
⏳ Cleanup backups - Remove backup files if no longer needed

Last Updated: 2025-01-20
Status: ✅ MIGRATION COMPLETE
Method: Backup/Restore with --dumpdir
Result: All 12 containers successfully migrated to r630-01
