Hi,
we are experiencing a weird issue with our Ovirt setup. We have two
physical hosts (DC1 and DC2) and mounted Lenovo NAS storage for all VM data.
They are connected via a managed network switch.
What happens is that if switch goes down for whatever reason (firmware
update etc), physical host reboots. Not sure if this is an action
performed by Ovirt but I suspect it is because connection to mounted
storage is lost and it performs some kind of an emergency action. I
would need to get some direction pointers to find out
a) who triggers the reboot and why
c) a way to prevent reboots by increasing storage? timeouts
Switch reboot takes 2-3 minutes.
These are the host /var/log/messages just before reboot occurs:

When leases expire, sanlock to terminate the lease owner (.e.g vdsm, qemu).
If the owner of the lease cannot be terminated in (~40 seconds) the sanlock must
reboot the host.
So the host running hosted engine may be rebooted because storage is
inaccessible
and qemu is stuck on storage.
Other hosts may have the same issue they run HA VMs, server as the SPM, or run
storage tasks that use a lease.
To understand if this is the case, we need complete sanlock.log and
vdsm.log from
the hosts, when the issue happens.
Please file ovirt vdsm bug for this, and attach relevant logs.
