[ovirt-users] thin_check run on VM disk by host on startup ?!

Hi,
While rebooting one of the hosts in an oVirt cluster, I noticed that
thin_check is run on the thin pool devices of one of the VM's on which
the disk is assigned to.
That seems strange to me. I would expect the host to stay clear of any
VM disks.
When I look at the 'lvs' output on the host, it seems to have activated
the VM's volume group that has the thin pool in it. It has also
activated one other volume group (and it's LV's) that is _not_ a thin
pool. All other VM disks are shown as LV's with their uuid. See output
below.
Is this expected behaviour? I would hope/expect that the host will never
touch any VM disks. Am I supposed to configure an LVM filter myself to
prevent this issue?
We had a thin pool completely break on an VM a while ago and I never
determined the root cause (was a test VM). If the host changed something
on the disk while the VM was running on the other host this might have
been the root cause.
Regards,
Rik
