Fails to mount CephFS from Mimic Cluster

[stefws]

I'm trying to mount a CephFS of a Mimic Cluster with a Luminous Client on a PVE 5.2 node, but are seeing this:

root@node7:~# grep ceph /etc/fstab
none /var/lib/ceph/backup fuse.ceph ceph.id=admin,_netdev,defaults 0 0

root@node7:~# mount /var/lib/ceph/backup
no valid command found; 10 closest matches:

Same mount works just fine on the Mimic Cluster CentOS7.5 nodes:

The fuse client isn't installed on PVE by default.

No... but thought that I already installed ceph-fuse, properly Jewel version before I alter to Luminous repo, anyway thanks for pointing out, it fixed the issue
