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:

   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

systemctl status ceph-mon@r630-01.service
journalctl -u ceph-mon@r630-01.service -n 20

Check Cluster Status

ceph quorum_status
ceph -s
ceph mon dump

Create OSDs (once cluster is operational)

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
