The hosted-engine storage domain is mounted for sure,
but the issue is here:
Exception: Failed to start monitoring domain (sd_uuid=7c8deaa8-be02-4aaf-b9b4-ddc8da99ad96, host_id=3): timeout during domain acquisition

The point is that in VDSM logs I see just something like:
2017-02-02 21:05:22,283 INFO  (jsonrpc/1) [dispatcher] Run and protect: repoStats(options=None) (logUtils:49)

Where the other storage domains have 'acquired': True whil it's always 'acquired': False for the hosted-engine storage domain.

Could you please share your /var/log/sanlock.log from the same host and the output of 
 sanlock client status
?

Hello,

I also put host in Maintenance and restarted vdsm while ovirt-ha-agent is running. I can mount the gluster Volume "engine" manually in the host.

I get this repeatedly in /var/log/vdsm.log:

I see there an ERROR on stopMonitoringDomain but I cannot see the correspondent  startMonitoringDomain; could you please look for it?

Hello,

attached is my vdsm.log from the host with hosted-engine-ha around the time-frame of agent timeout that is not working anymore for engine (it works in Ovirt and is active). It simply isn't working for engine-ha anymore after Update.

At 2017-02-02 19:25:34,248 you'll find an error corresponoding to agent timeout error.

Bye

3. Three of my hosts have the hosted engine deployed for ha. First all three where marked by a crown (running was gold and others where silver). After upgrading the 3 Host deployed hosted engine ha is not active anymore.

I can't get this host back with working ovirt-ha-agent/broker. I already rebooted, manually restarted the services but It isn't able to get cluster state according to
"hosted-engine --vm-status". The other hosts state the host status as "unknown stale-data"

I already shut down all agents on all hosts and issued a "hosted-engine --reinitialize-lockspace" but that didn't help.

Agents stops working after a timeout-error according to log:
