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:
