[PVE-User] Cannot create container with Proxmox 4.4 and CEPH 12.2.2

[Iztok Gregori]

Hi!

I'm not sure I've found a bug or I'm missing something. Today I've tried 
to create a new LXC container on a CEPH RBD storage and the creation 
failed with the output:

pvedaemon[19601]: Could not parse Ceph version: 'ceph version 12.2.2 
(cf0baeeeeba3b47f9427c6c97e2144b094b7e5ba) luminous (stable)'
pvedaemon[19601]: Use of uninitialized value $major in numeric lt (<) at 
/usr/share/perl5/PVE/Storage/RBDPlugin.pm line 111.
pvedaemon[19601]: can't mount rbd volume vm-147-disk-2: rbd: sysfs write 
failed

The image was created on CEPH, but the container was not. We upgraded 
CEPH from Hammer to Luminous and this was the first container creation 
after the upgrade (with Hammer containers were created without 
problems). Other than this we don't have any other problem with Proxmox 
and CEPH.

I diged a little bit and it seems that the function 
"ceph_version_parser" (in RBDPlugin) is not parsing correctly the output 
of "ceph --version".

I've checked if the file/package is outdated, but it seems that 
"libpve-storage-perl" is the latest one available (4.0-76) and I didn't 
found any references about this behavior.

Have you similar experiences?
