PBS statistics do not work on CephFs

[flames]

Hello,

I run PBS as a VM on a separate PVE + Ceph cluster (dedicated for backups). All versions are up-to-date (no subscription repo).
CephFS is mounted via fstab into the PBS-VM:

bc01,bc02,bc03,bc04:/PBS/    /ceph-bak       ceph    _netdev,noatime,name=backupuser,secretfile=/etc/ceph/backupcluster.backupuser.secret       0 2

datastore.cfg (cutdown):

datastore: datastorename
        path /ceph-bak/datastorename

This setup works perfectly and is acceptable fast.

PBS GUI does not show any datastore graphs except of storage usage. Is this, because those graphs use specific filesystem tools to get the data?

Thanks in advance

Roughly speaking, yes. It tries to read ZFS pool stats or blockdevice stats. Generally, Proxmox Backup Server focuses on local storage like ZFS.
