Proxmox Web-interface

Case 1. Root cephfs01 mount

• Datacenter - Storage - Add CephFS:
  • ID: cephfs01
  • Monitor(s): 192.168.199.121 192.168.199.122 192.168.199.123  # IPs of ceph nodes with MONITORs
  • User name: admin
  • FS Name: cephfs01
  • Secret key: <key> # Get key on the Ceph Server: cat /etc/ceph/ceph.client.admin.keyring | awk -F" = " '/key/{print $2}'

Case 2. Subdirectory cephfs01/pve mount

Remove created via web-interface Ceph Storage (like above), if you've already created it, of course.

Unmount storage via CLI manually:

umount  /mnt/pve/cephfs01

Add "subdir /pve" to config file:

nano /etc/pve/storage.cfg

cephfs: cephfs01-pve
        path /mnt/pve/cephfs01
        content iso,snippets,backup,vztmpl
        fs-name cephfs01
        monhost 192.168.199.121 192.168.199.122 192.168.199.123
        prune-backups keep-all=1
        subdir /pve
        username admin

Now there's new CephFS entry appeared in the web-interface. Enable it!

Populate keyring to other PVE hosts (if you have a PVE cluster)

scp /etc/ceph/ceph.client.user03.keyring pve02:/etc/ceph/

scp /etc/ceph/ceph.client.user03.keyring pve03:/etc/ceph/
