Engine insists on running on 1 host in cluster when that host is online
by David White 16 Oct '21

16 Oct '21

About a month ago, I completely rebuilt my oVirt cluster, as I needed to move all my hardware from 1 data center to another with minimal downtime. All my hardware is in the new data center (yay for HIPAA compliance and 24/7 access, unlike the old place!) I originally built the cluster as a single-node hyperconverged. I then added nodes to it, and then, finally, I reconfigured gluster to run in a replica 2 / arbiter 1 configuration. As of now: - I have 4 compute hosts - Gluster is running fine and replicating fine between the two full replicas, along with the arbiter node - I need to revisit my recent email about gluster replication speed, though However, I'm worried about two things: - I think that my hosts, and hosted-engine, are all still configured to use the single mount point from the original single-node hyperconverged ... i.e. if I shutdown / reboot that host, then the storage "goes away" - How do I reconfigure oVirt to use the 2nd replica as a secondary mount point? - Currently, the Engine is deployed on two of the servers (a and c). But any time one of those servers is online (c), the hosted-engine insists on running on that server c. I cannot migrate the engine off of c. And if the engine is running on the other host a, then I turn host c back on, the engine shuts down from a, and comes back up on c. - How do I "fix" this so that the engine will run on host a, even when host c is turned on? - How do I deploy the hosted-engine to host b? - Is it as simple as logging into host b, and running "hosted-engine --deploy" ?

Sometimes, some vm failed to stop it by press the shutdown button on the management portal, it will show such message in log: shutdown of vm *** failed. And I want to know: 1. why cannot shutdown it normally ? 2. what difference between the shutdown and power off ? (For example, what are the different signals sent to the QEMU process) Thanks.

How to add a note to a VM
by Gianluca Cecchi 12 Oct '21

12 Oct '21

Hello, I know there are the "Comment" and "Description" columns available in many areas of the Webadmin Gui. But there are some tasks, like "shutdown VM" or "Management -> Maintenance" for a host, where I can specify a "reason" for doing that task and then a note icon appears, aside the object, with the mouse over showing the note text, like in this image: https://drive.google.com/file/d/1v3Yd2t7AtuRFMT6HPFYYZqYUmJLMHYMY/view?usp=… Is there a way to do it in general? So for example I have a VM and I want to put a note (for some colleague, or to remind me to do an action tomorrow, ecc...) And btw: how can I manually remove the note? Eg I shutdown a VM and fill in the "Reason" field and then in a second moment I want to remove it.... Thanks in advance, Gianluca

Hosted Engine ansible runner artifacts cleanup
by Erez Zarum 11 Oct '21

11 Oct '21

Hey, I can't get the artifacts to cleanup, i have configured the ansible runner config.yml but it seems not to be running. Should i restart the ovirt-engine service? What is the best way to manually cleanup the artifacts (i can't get the correct ansible-runner command to clean it up) as it is starting to fill up disk space Thanks

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Ax Olmos 10 Oct '21

10 Oct '21

The problem is that the ‘glusterd_brick_t’ file context is missing from selinux-policy-targeted 3.14.3-80 on CentOS 8 Stream. It exists in the CentOS 8.4 version: rpm -qpl selinux-policy-targeted-3.14.3-67.el8_4.2.noarch.rpm | grep gluster /usr/share/selinux/targeted/default/active/modules/100/glusterd /usr/share/selinux/targeted/default/active/modules/100/glusterd/cil /usr/share/selinux/targeted/default/active/modules/100/glusterd/lang_ext /var/lib/selinux/targeted/active/modules/100/glusterd /var/lib/selinux/targeted/active/modules/100/glusterd/cil /var/lib/selinux/targeted/active/modules/100/glusterd/hll /var/lib/selinux/targeted/active/modules/100/glusterd/lang_ext Not on CentOS 8 Stream: rpm -qpl selinux-policy-targeted-3.14.3-80.el8.noarch.rpm | grep gluster You can remove the selinux checks from: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/mount.yml but I’m not sure of the implications of that. This is a show stopper for oVirt and someone from oVirt needs to contact the CentOS 8 Stream maintainers and have them put the selinux context back, or come up with some other workaround.
