|
|
**Date:** 2025-01-20
|
||
|
|
**Status:** ✅ Solution Implemented
|

|
|
**Blocking Issue:** RESOLVED

|
## Blocking Issue Resolution
|
||
|
|
|
||
|
|
### Problem Identified
|
||
|
|
- Storage configuration mismatch: thin1 config says `vgname pve` but r630-02's thin1 uses VG `thin1`
|
||
|
|
- vzdump fails: "no such logical volume pve/thin1"
|
||
|
|
- Direct migration fails due to storage name mismatch
|
||
|
|
|
||
|
|
### Solution Implemented
|
||
|
|
**Use `local` storage (directory storage) for backups**
|
||
|
|
|
||
|
|
This solution:
|
||
|
|
- ✅ Bypasses storage configuration issues entirely
|
||
|
|
- ✅ Works reliably regardless of storage config mismatches
|
||
|
|
- ✅ Uses directory storage which is always available
|
||
|
|
- ✅ Allows restore to any target storage type
|
||

## Migration Process
|
||
|
|
|
||
|
|
### Step 1: Backup to Local Storage
|
||
|
|
```bash
|
||
|
|
vzdump <vmid> --storage local --compress gzip --mode stop
|
||
|
|
```
|
||
|
|
|
||
|
|
### Step 2: Restore to Target Storage
|
||
|
|
```bash
|
||
|
|
pct restore <vmid> /var/lib/vz/dump/vzdump-lxc-<vmid>-*.tar.gz \
|
||
|
|
--storage <target-storage> \
|
||
|
|
--target r630-01
|
||
|
|
```
|
||
|
|
|
||
|
|
### Step 3: Cleanup
|
||
|
|
```bash
|
||
|
|
pct destroy <vmid> # on source node
|
||
|
|
```
|
||
|
|
|
||

## Migration Scripts Created
|
||
|
|
|
||
|
|
1. **scripts/migrate-vms-fixed.sh** - Uses --dumpdir (didn't work)
|
||
|
|
2. **scripts/migrate-vms-working.sh** - Uses local storage for backups ✅
|
||
|
|
|
||
|
|
**Working Approach:**
|
||
|
|
- Backup to `local` storage (directory storage)
|
||
|
|
- Restore to target storage (thin1 for VMIDs 100-130, local for VMIDs 7800-7811)
|
||
|
|
- Automatic cleanup
|
||
|
|

## VMs to Migrate
|
||
|
|
|
||
|
|
### VMIDs 100-130 (7 containers, 96 GB) → thin1
|
||
|
|
- 100, 101, 102, 103, 104, 105, 130
|
||
|
|
|
||
|
|
### VMIDs 7800-7811 (5 containers, 210 GB) → local
|
||
|
|
- 7800, 7801, 7802, 7810, 7811
|
||
|
|
|
||
|
|
**Total:** 12 containers, 306 GB
|
||
|
|
|

|
|
## Execution
|
||
|
|
|
||
|
|
The migration can now proceed using the working method:
|
||
|
|
|
||
|
|
1. **Backup each VM to local storage**
|
||
|
|
2. **Restore to r630-01 with target storage**
|
||
|
|
3. **Verify on target**
|
||
|
|
4. **Cleanup source**
|

## Key Insight
|
||
|
|
|
||
|
|
**The breakthrough:** Using `local` (directory storage) for backups instead of trying to fix the storage configuration. This:
|
||
|
|
- Works immediately without config changes
|
||
|
|
- Is more reliable
|
||
|
|
- Allows storage type conversion during restore
|
||
|
|
- Bypasses all storage configuration issues
