I have one node cluster (ovirt version 3.2) and this node went down because kernel panic. In wui I can see it is down, but VMs are still reported to be running. (they dont, ofcourse..) I manualy rebooted that host and now it is up. But problem is, that I can not activate it in wui (still red)

If I press "Confirm 'Host has been Rebooted'" it says:

Manual fence did not revoke the selected SPM (node1.site.com) since the master storage domain was not active or could not use another host for the fence operation.

If I try to put host in maitenance it says:

Error while executing action: Cannot switch the following Hosts to Maintenance mode: node1.site.com.
One or more running VMs are indicated as non-migratable. The non-migratable VMs are: vm2.site.com.

I removed "HA mode" from vm2.site.com, but did not do the job.

I can not even Power off running hosts.

Is there any way what to do?

Thank you,
Jakub Bittner

The VMs have question mark in their statuses. Can you attach vdsm.log of your hypervisor? I guess there will be error messages like missing logical volumes or libvirt getcapability check issues. Have seen these and host-behavior was the same as in your case. I solved it by changing storage to local NFS. Didn't had enough time to report bugs, yet - sorry for this.
