# r630-01 thin1 Storage Fix

**Date:** 2025-01-20  
**Status:** ✅ Fixed  
**Issue:** thin1 storage configuration was incorrect

---

## Problem Identified

### Configuration Issues

The thin1 storage configuration on r630-01 had multiple issues:

1. **Wrong Volume Group:** Config specified `vgname thin1`, but r630-01 has VG `pve`
2. **Wrong Node Reference:** Config specified `nodes r630-02`, but should be `r630-01`
3. **Wrong Thin Pool:** Config specified `thinpool thin1`, but the `thin1` LV is not a thin pool
4. **Storage Status:** thin1 showed as disabled/invalid

### Actual Storage Situation

**r630-01 LVM:**
- **Volume Group:** `pve` (not `thin1`)
- **Thin Pool:** `data` (200GB, used by local-lvm)
- **Logical Volume:** `thin1` (208GB, but NOT a thin pool - just a regular LV)

**Storage Configuration:**
- `local-lvm`: ✅ Active, uses `pve/data` thin pool (200GB)
- `thin1`: ❌ Disabled, incorrect configuration

---

## Solution Applied

### Option Considered

Since:
- `local-lvm` is already available and working (200GB)
- `thin1` config was incorrect and pointed to wrong VG/node
- The `thin1` LV is not a thin pool (would need conversion)
- `local-lvm` provides sufficient storage for current needs

**Decision:** Remove the incorrect thin1 storage configuration.

### Actions Taken

1. **Backed up** storage configuration
2. **Removed** incorrect thin1 storage config from `/etc/pve/storage.cfg`
3. **Verified** storage status

---

## Result

### Current Storage Status

**r630-01 Available Storage:**

| Storage | Type | Status | Size | Available |
|---------|------|--------|------|-----------|
| **local-lvm** | lvmthin | ✅ Active | 200 GB | 200 GB |
| local | dir | ✅ Active | 536 GB | 536 GB |

**Total Available:** 736 GB

### thin1 Status

- ❌ thin1 storage configuration removed (was incorrect)
- ✅ `thin1` LV still exists (208GB, can be converted to thin pool if needed later)
- ✅ `local-lvm` provides sufficient storage (200GB)

---

## Future Options

If additional thin storage is needed in the future:

### Option 1: Convert thin1 LV to Thin Pool

```bash
# Convert thin1 LV to thin pool
lvconvert --type thin-pool pve/thin1

# Add storage
pvesm add lvmthin thin1 \
    --thinpool pve/thin1 \
    --vgname pve \
    --content images,rootdir \
    --nodes r630-01
```

### Option 2: Use Existing Storage

- `local-lvm` (200GB) - sufficient for current needs
- `local` (536GB) - directory storage, available if needed

---

## Summary

✅ **Issue Fixed:**
- Removed incorrect thin1 storage configuration
- Storage now clean and correct
- `local-lvm` available for use (200GB)

✅ **Storage Available:**
- `local-lvm`: 200 GB (LVM thin, recommended)
- `local`: 536 GB (directory storage)
- Total: 736 GB available

✅ **Status:**
- Storage configuration corrected
- No invalid/disabled storage entries
- Ready for VM deployment
