The response was that when I select the oVirt HCI storage volumes to deploy to (with VDO enabled) which are a single 512GB SSD with only one small IDM VM running. The IPI OCP 4.7 deployment fails. RH closed ticket because "gluster volume is too slow".
I then tried to create with my other 1TB SSD in each server gluster volume without VDO and see if that worked.. but though I matched all settings / gluster options oVirt set, IPI OCP would not show disk as deployable option. I then figured I would use GUI to create bricks vs ansible means (trying to be good and stop doing direct shell but build as ansible playbooks).. but that test is on hold because servers for next two weeks are being re-tasked for another POC. So I figured I would do some rethinking if oVirt HCI on RHEV 4.5 with Gluster is a rat hole that will never work. Below is the output from fio test OCP team asked me to run to show gluster was too slow. ################## ansible@LT-A0070501:/mnt/c/GitHub/penguinpages_cluster_devops/cluster_devops$ ssh core@172.16.100.184 [core@localhost ~]$ journalctl -b -f -u release-image.service -u bootkube.service -- Logs begin at Sun 2021-04-11 19:18:07 UTC. -- Apr 13 11:50:23 localhost bootkube.sh[1276476]: [#404] failed to fetch discovery: Get "https://localhost:6443/api?timeout=32s": x509: certificate has expired or is not yet valid: current time 2021-04-13T11:50:23Z is after 2021-04-12T19:12:30Z Apr 13 11:50:23 localhost bootkube.sh[1276476]: [#405] failed to fetch discovery: Get "https://localhost:6443/api?timeout=32s": x509: certificate has expired or is not yet valid: current time 2021-04-13T11:50:23Z is after 2021-04-12T19:12:30Z <snip> [core@localhost ~]$ su - Password: su: Authentication failure [core@localhost ~]$ sudo podman run --volume /var/lib/etcd:/var/lib/etcd:Z quay.io/openshift-scale/etcd-perf Trying to pull quay.io/openshift-scale/etcd-perf Trying to pull quay.io/openshift-scale/etcd-perf...
