[ovirt-users] Hosted-Engine environment, strange messages in event log

Any suggestion what can be the reason for those strange messages (repeating every hour) in the web gui event log: Nov 11, 2017 7:07:01 PM Status of host ovirt2.prod.env was set to Up. Nov 11, 2017 7:06:54 PM Failed to update OVF disks 94b7554b-4c18-4296-b795-98ca6c0fb251, 002af29c-58df-493d-a45c-5009d4dfc1de, OVF data isn't updated on those OVF stores (Data Center oVirtDC, Storage Domain oVirtMigration).

Nov 11, 2017 6:06:48 PM Host ovirt2.prod.env is not responding. Host cannot be fenced automatically because power management for the host is disabled. Power Management is not configured yet, plaqnning to test it on coming week. So far I have one host serving 5 VM's + hosted_engine. I was planning to add one more host to the cluster this week. All storage domains running on GlusterFS cluster. Regards, Artem
