[ovirt-users] Unable to Manage Snapshots Using UI
I want to delete some old snapshots, but when I try to access the list of snapshots in using the engine UI I get "Uncaught exception occurred...Details: Exception Caught: html is null..."

This is a stupid question, but how do I attach a file to this post? I am using the web form, as soon as I figure out this mailing list thing I will attach full logs (NB) Regardless, there are no logs before the reboot of Node1 in sanlock.log on that day. Node1 started coming back online at 10:04AM. 2018-09-08 09:19:38 3081 [1127]: s1 host 2 16 249 f9704a0b-9a09-42f4-819c-35055c1177af.node2. 2018-09-10 10:03:54 5 [1154]: sanlock daemon started 3.6.0 host edfe4d27-bdbe-45e3-9e4c-a4e02b2101bd.node1.

[ovirt-users] Re: Host restarting for unknown reasons
We originally noticed an issue when the host would restart at midnight on Saturdays EST time. The other day it restarted at 10AM EST which was a surprise. The system is under low load and no hardware issues were found in iDRAC nor in kernel messages. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/37CJPQ6G3V54K2NB2K7U6JKEOIO6YQZ5/

[ovirt-users] Host restarting for unknown reasons
I have a dual host, self hosted engine, cluster/datacenter. I call these Node1
and Node2. They are running CentOS 7 and I have been running the updates
regular by putting each host into maintenance mode and installing the update
via the web gui.
Node1 is restarting at odd times, causing VMs on that node to start up on Node2
(which is by design). However the restarts are becoming more frequent and I am
having a hard time figuring out what is causing it. Below is a snippet from the
/var/log/ovirt-hosted-engine-ha/agent.log on Node1. My current plan is to
simply rebuild Node1 by re-installing CentOS 7, and using the cluster tools to
import it.
