# Ceph Cluster Current State - sfvalley-01
**Date**: 2025-12-15 15:18 PST
**Status**: ⚠️ **CLUSTER NOT FULLY OPERATIONAL**
## Summary
The Ceph cluster on ml110-01 exists but is not responding to commands. The monitor is running but in "probing" state and cannot form quorum, which prevents:
- Adding r630-01 monitor
- Creating OSDs
- Querying cluster status
## Current Configuration
### Both Nodes (Synced via Proxmox cluster)
```
[global]
auth_client_required = cephx
auth_cluster_required = cephx
auth_service_required = cephx
cluster_network = 192.168.11.0/24
fsid = 021d20d3-446f-42cb-a219-5e01213b7b2d
mon_allow_pool_delete = true
mon_host = 192.168.11.10 192.168.11.11
ms_bind_ipv4 = true
ms_bind_ipv6 = false
osd_pool_default_min_size = 2
osd_pool_default_size = 3
public_network = 192.168.11.0/24
[client]
keyring = /etc/pve/priv/$cluster.$name.keyring
[client.crash]
keyring = /etc/pve/ceph/$cluster.$name.keyring
[mon.ml110-01]
public_addr = 192.168.11.10
[mon.r630-01]
public_addr = 192.168.11.11
```
## Service Status
### ML110-01
- ✅ ceph-mon@ml110-01.service: **ACTIVE (running)**
- ⚠️ Monitor state: "probing" (cannot form quorum)
- ❌ Ceph commands: Timeout (cluster not accessible)
### R630-01
- ❌ ceph-mon@r630-01.service: **FAILED** (filesystem not created)
- ⚠️ Cannot create monitor without monmap from ml110-01
- ⚠️ Cannot create OSDs without cluster access
## Available Disks for OSDs (R630-01)
- `/dev/sdc`: 232.9G (CT250MX500SSD1)
- `/dev/sdd`: 232.9G (CT250MX500SSD1)
- `/dev/sde`: 232.9G (CT250MX500SSD1)
- `/dev/sdf`: 232.9G (CT250MX500SSD1)
- `/dev/sdg`: 232.9G (CT250MX500SSD1)
- `/dev/sdh`: 232.9G (CT250MX500SSD1)
**Total Available**: ~1.4TB across 6 SSDs
## Blocking Issues
1. **Monitor Quorum Not Established**
- ML110-01 monitor in "probing" state
- Cannot form quorum with single monitor
- R630-01 monitor cannot be added without quorum
2. **Cluster Commands Timeout**
- `ceph -s`: Timeout
- `ceph mon getmap`: Timeout
- `ceph quorum_status`: Timeout
- Cannot query or manage cluster
3. **Monitor Filesystem Not Created**
- R630-01 monitor directory exists but is empty
- Needs monmap and keyring from ml110-01
- Cannot create without cluster access
## Recommended Solutions
### Option 1: Use Proxmox Web UI (Recommended)
The Proxmox web interface may handle the monitor and OSD creation more reliably:
1. Access Proxmox web UI
2. Navigate to: Datacenter > Ceph > Monitors
3. Add r630-01 monitor through UI
4. Navigate to: Datacenter > Ceph > OSDs
5. Create OSDs on r630-01 disks through UI
### Option 2: Reinitialize Ceph Cluster
If the cluster is not critical or can be reinitialized:
1. Stop Ceph on ml110-01
2. Remove existing Ceph data
3. Reinitialize cluster with proper configuration
4. Add r630-01 monitor
5. Add OSDs
### Option 3: Fix Monitor Quorum
If there's existing data that must be preserved:
1. Investigate why ml110-01 monitor is in "probing" state
2. Check monitor logs for errors
3. Fix underlying issue preventing quorum
4. Then add r630-01 monitor
## Next Steps
1. **Investigate Monitor Issue**: Check why ml110-01 monitor cannot form quorum
2. **Use Web UI**: Try adding monitor and OSDs through Proxmox web interface
3. **Or Reinitialize**: If acceptable, reinitialize cluster with proper setup
## Notes
- Configuration is correct and synced across cluster
- Network connectivity is working (ping successful)
- Monitor ports are open (6789, 3300)
- Issue appears to be with monitor quorum formation
- May require cluster reinitialization or web UI approach
