Hi,
I have a 3-node CentOS7 based oVirt+replica-3 gluster environment with an engine on dedicated hardware.
After putting the first vm-host into maintenance mode to update it from vdsm-4.17.28-1 to vdsm-4.17.32-0 and from glusterfs-3.7.11-1 to glusterfs-3.7.12-2 (among others), random VMs froze (not pauzed. oVirt showed them as 'up') until the update was done and the vm-host was rebooted and active again.
I suppose the host you were updating at that time had no running VMs, right? If so, then indeed perhaps a gluster issue
After all the vm-hosts were upgraded, I never experienced the problem again. Can this be a bug, fixed with the upgrade to glusterfs-3.7.12-2?
Has anyone experienced the same problem?
Thanks in advance! (next week I'm not able to check my e-mail, so response can be delayed).
Regards,
Bertjan
