### Verification Commands
```bash
# Check remaining Ceph packages
dpkg -l | grep ceph

# Check Ceph services
systemctl list-units --all | grep ceph

# Check data directories
ls -la /var/lib/ceph /etc/ceph /etc/pve/ceph.conf

# Check for Ceph binaries
which ceph-mon ceph-osd ceph-mgr
```

## Notes

- **Proxmox Protection**: Some Ceph packages may remain if Proxmox VE requires them as dependencies
- **Client Tools**: `ceph-common` and `ceph-fuse` may remain if needed by Proxmox storage features
- **No Reinstallation**: As requested, Ceph has NOT been reinstalled
- **Clean State**: All Ceph cluster data and configuration has been removed
- **Proxmox Cluster**: Still intact and operational (sfvalley-01)

## Next Steps (If Needed)

If you need to completely remove all Ceph packages including client tools:
```bash
# This may require touching the Proxmox protection file
touch /please-remove-proxmox-ve
apt remove --purge ceph-common ceph-fuse
```

However, this is generally not recommended as Proxmox may use these for storage features.
