[Users] Ovirt Node rebooting +/- every 10 days

[EricD]

I have oVirt 3.1 with two nodes, one of them is running good without
restarting the other keep restarting, the maximum uptime that the server
can get is 10 days before it restart, I think that it might be something
related to the disk.

FYI, the disk are 2 disk of 1TB (RAID-0) to get 2TB.
