Verification Commands

# 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:

# 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.
