# Ceph Setup Progress Summary - sfvalley-01

**Date**: 2025-12-15 15:25 PST  
**Status**: ⚠️ **PARTIAL SUCCESS - Monitor Filesystem Created, Service Issues Remain**

## Completed Steps

### ✅ Infrastructure Setup
1. **SSH Key Authentication**: Configured for both servers
2. **Disk Layout Documentation**: fdisk output documented for both servers
3. **Ceph Packages**: Installed on both ml110-01 and r630-01 (19.2.3-pve2)
4. **Proxmox Cluster**: r630-01 successfully joined cluster "sfvalley-01"

### ✅ Configuration
1. **Ceph Configuration**: Updated and synced across cluster
   - Network: 192.168.11.0/24 (corrected from 192.168.11.11/24)
   - FSID: 021d20d3-446f-42cb-a219-5e01213b7b2d
   - Monitor hosts: 192.168.11.10, 192.168.11.11
   - Both monitor sections configured

### ✅ Monitor Setup Progress
1. **Monmap Extracted**: Successfully extracted from ml110-01 monitor
2. **Monitor Keyring**: Retrieved from ml110-01
3. **Monitor Filesystem Created**: `/var/lib/ceph/mon/ceph-r630-01/` filesystem created with:
   - keyring
   - kv_backend
   - store.db directory

## Current Issues

### ⚠️ Monitor Service
- **Status**: Monitor filesystem exists but service fails to start
- **Error**: Service exits with code 1
- **Location**: `/var/lib/ceph/mon/ceph-r630-01/` exists with proper structure
- **Next Step**: Investigate why service fails despite filesystem being created

### ⚠️ Cluster Accessibility
- **Status**: Ceph commands timeout
- **Impact**: Cannot verify quorum, cannot create OSDs
- **Root Cause**: ML110-01 monitor in "probing" state, cannot form quorum
- **Next Step**: Resolve monitor quorum issue on ml110-01

### ⚠️ OSD Creation
- **Status**: Cannot create OSDs (cluster not accessible)
- **Available Disks**: 6x 232.9G SSDs on r630-01 (/dev/sdc through /dev/sdh)
- **Next Step**: Create OSDs once cluster is operational

## Technical Details

### Monitor Filesystem Structure (r630-01)
```
/var/lib/ceph/mon/ceph-r630-01/
├── keyring (77 bytes)
├── kv_backend (8 bytes)
└── store.db/ (database directory)
```

### Configuration Files
- **Location**: `/etc/pve/ceph.conf` (synced via Proxmox cluster)
- **Status**: ✅ Correct and synced
- **Monitors Configured**: ml110-01, r630-01

## Next Steps

### Priority 1: Fix Monitor Service
1. Check detailed error logs: `journalctl -xeu ceph-mon@r630-01.service`
2. Verify filesystem permissions and ownership
3. Check if monitor can connect to ml110-01
4. Resolve service startup issue

### Priority 2: Establish Monitor Quorum
1. Investigate why ml110-01 monitor is in "probing" state
2. Check monitor logs for errors
3. Verify network connectivity between monitors
4. Ensure both monitors can form quorum

### Priority 3: Create OSDs
1. Once cluster is accessible, create OSDs on r630-01:
   ```bash
   pveceph osd create /dev/sdc
   pveceph osd create /dev/sdd
   pveceph osd create /dev/sde
   pveceph osd create /dev/sdf
   pveceph osd create /dev/sdg
   pveceph osd create /dev/sdh
   ```

## Commands Reference

### Check Monitor Status
```bash
systemctl status ceph-mon@r630-01.service
journalctl -u ceph-mon@r630-01.service -n 20
```

### Check Cluster Status
```bash
ceph quorum_status
ceph -s
ceph mon dump
```

### Create OSDs (once cluster is operational)
```bash
pveceph osd create /dev/sdc
# Repeat for sdd, sde, sdf, sdg, sdh
```

## Notes

- Monitor filesystem was successfully created using monmap and keyring from ml110-01
- Configuration is correct and synced across Proxmox cluster
- The main blocker is the monitor service not starting and cluster not being accessible
- May need to investigate deeper into monitor logs or use Proxmox web UI for final setup
