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

[Marco M. Gabriel]

You can enable the pg-autoscaler. It does the work for you and
optimizes the number of placement groups on a given pool.

The pg-autoscaler was introduced with nautilus and we ran it for a
while without any problems.

Here is an explanation of how to enable and how to use the autoscaler:

Best regards,
