[PVE-User] ProxmoxVE6.3/CEPH Octopus 15.2.6 was Python problem with upgrade to proxmoxVE6.3/ CEPH Nautilus 14.2.15

[Jean-Daniel TISSOT <Jean-Daniel.Tissot@univ-fcomte.fr>]

Sorry to steal the thread.

In fact before upgrading to Octopus, I don't remember any warning.

I upgrade Proxmox an follow the wiki to upgrade CEPH. All things seam 
working (I don't test HA by migrate a VM work perfectly.

I have just the warning on pool rdb (1 pools have too many placement 
groups Pool rbd has 128 placement groups, should have 32)
