12 Oct '21

Hi all, I'm happy to share with you my new oVirt blog: Visualize and Monitor the oVirt environment with Grafana <https://blogs.ovirt.org/2021/10/visualize-and-monitor-the-ovirt-environment…> . In this blog we’ll explore how to monitor the oVirt environment so you can visualize performance, resources and trends. In this blog: - How to use oVirt dashboards. - Explanation of default dashboards. - How to create custom dashboards from the built-in options that come with oVirt. Feedback, comments and suggestions are more than welcome! -- Aviv Litman BI Associate Software Engineer Red Hat <https://www.redhat.com/> alitman(a)redhat.com <https://www.redhat.com/>

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

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.

Slow gluster replication
by David White 10 Oct '21

10 Oct '21

I can't remember if I've asked this already, or if someone else has brought this up. I have noticed that gluster replication in a hyperconverged environment is very slow. I just (successfully, this time) added a brick to volume that was originally built on a single-node Hyperconverged cluster. One of my volumes has over 600GB, but the network is 10Gbps, so replication really shouldn't take that long. It's been over two hours, and that volume has only replicated a little over 400GB. It feels like it's taking about 1GB every 30 seconds - 1 minute or so... Why would this replication be so slow? Sent with ProtonMail Secure Email.

Configuring LUNS for self-hosted engine install
by Virden, Gerald 08 Oct '21

08 Oct '21

Hi, I have a host with two 16TB LUNS that I want to deploy a self-hosted engine on. I have so far been unsuccessful; the install either fails or hangs and Oracle is saying it is due to storage. I can see both LUNS with multipath -ll. Does anyone know of step by step instructions on what to do to configure the LUNS so the engine will see them and set up the storage domain? Jerry

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Eddie Garcia 07 Oct '21

I have been having this issue as well with no solution working but I came across something interesting. In selinux-policy 3.14.3-77 they removed the glusterd selinux module. https://centos.pkgs.org/8-stream/centos-baseos-x86_64/selinux-policy-3.14.3… so that policy doesn exist anymore for ansible to apply. I plan on testing installing an older version into an ovirt node box to test which defaults as of 4.4.8 to selinux-policy version 3.14.3-79.el8. A clean install of CentOS 8 using latest iso has version 3.14.3-67.el8_4.2 and I can verify that manually setting policy with command 'semanage fcontext -a -t glusterd_brick_t "/gluster_bricks(/.*)?"' is completed successfully.

Which version of oVirt are you using? There were improvements for the delay of initial guest information in oVirt 4.4 and the information should be available as soon as the VM comes up.
