Hi,

the issue seems to be that host-1 stopped responding and I can see some fluetd errors which we should look at.

Jira opened to track this issue: https://ovirt-jira.atlassian.net/browse/OVIRT-2363

Martin, I also added you to the Jira - can you please have a look?

​Hi,

I can see in vdsm.log that it received a kill signal:

2018-07-23 05:24:26,735-0400 INFO  (MainThread) [vds] Received signal 15, shutting down (vdsmd:68)

​And in /var/log/messages I found that mom was killed:

Jul 23 05:24:16 lago-basic-suite-master-host-1 systemd: Stopping MOM instance configured for VDSM purposes...

...

Jul 23 05:24:26 lago-basic-suite-master-host-1 systemd: mom-vdsm.service stop-sigterm timed out. Killing.
Jul 23 05:24:26 lago-basic-suite-master-host-1 systemd: mom-vdsm.service: main process exited, code=killed, status=9/KILL
Jul 23 05:24:26 lago-basic-suite-master-host-1 systemd: Stopped MOM instance configured for VDSM purposes.
Jul 23 05:24:26 lago-basic-suite-master-host-1 systemd: Unit mom-vdsm.service entered failed state.
Jul 23 05:24:26 lago-basic-suite-master-host-1 systemd: mom-vdsm.service failed.

So Didi/Shirly/Martin can fluentd error be related to mom shutdown? And could this be a cause of VDSM shutdown?

Change 92882,9 (ovirt-engine) is probably the reason behind recent system test
failures in the "ovirt-master" change queue and needs to be fixed.

This change had been removed from the testing queue. Artifacts build from this
