[PVE-User] PVE 2.1 and DRBD...

Just a note

Do not do that:

filter = [ "r|/dev/sdb1|", "r|/dev/disk/|", "r|/dev/block/|", "a/.*/" ]

But this:

filter = [ "r|/dev/sdb1|" ]

If you put /dev/disk and /dev/block you will crash your system, since PVE
need mount a LVM space to boot the system:

/dev/mapper/pve-root

and others...
