I have an issue with ovirt where it thinks a task "Handling non responsive host hv1" is stuck Executing. Every time, after the server is fenced and comes back online, when I try to activate it this host is fenced/rebooted. What happened before the attempt to reboot was related to doing normal OS updates as follows.

1. Update OS/RPMs on ovirt engine host and reboot it

2. Move all VMs from hv1 to other hypervisors and put into maintenance mode

3. install updates via ovirt web application by right clicking hosts and selecting "upgrade"

4. install all available updates via yum and reboot hosts

5. Once hosts has rebooted right click > confirm host has been rebooted

6. attempt to activate hosts

At this point the hosts was fenced forcing a reboot and now I can't seem to get this host up and working. I noticed that with the yum updates or ovirt upgrade option it installed a 3.8.x virsion of glusterfs packages which currently everything else is running 3.7.x versions so I downgraded the ovirt rpms to the previous version. Manually rebooted and attempted to activate the host which produced a fencing of this hosts and still a Handling non responsive host task in the ovirt web interface. My thought on the ovirt is that the host, after being upgraded to the newer glusterfs rpms, couldn't connect properly to the gluster sans.

I'm not sure what else to check or do here since I believe until this stuck task is cleared this hosts will continue to be fenced everytime I try to activate it.

I can ping all 3 gluster sans and the ovirt engine server from this affected hosts.

Running:

ovirt 4.0.6.1-1

glusterfs 3.7.20-1

All hosts/sans are running CentOS 7.3 and the one I upgraded now shows 7.4
