I have been building out HCI stack with KVM/RHEV + oVirt with the HCI
deployment process. This is very nice for small / remote site use cases, but
with Gluster being anounced as EOL in 18 months, what is the replacement plan?
Are their working projects and plans to replace Gluster with CEPH?
Fresh install CentOS8 Streams. Gluster wizard runs and deploys. Engine
installs on node.
I copy over /etc/hosts for primary site resources to ovirt engine so it can
find primary cluster nodes without DNS being booted / up at that time.
I check ovirt engine can ssh to the three nodes... so
well.. figured the package remove was means to get rid of "upgrade pending"
which would then allow me to get engine failover to start working but...
ya.. don't do that.
How to destroy engine:
1) yum update --allowerasing
2) reboot
3) no more engine starting.
I did make that post but that was more about convert to CentOS 8 to streams
fubar my cluster up... ya.. still trying to get it back on its feet.
I have been trying to move to IaC based deployment but .. kind of given up on
that as oVirt seems to really need its last steps "HCI Wizard"
yum
Fresh install of minimal CentOS8
Then deploy:
- EPEL
- Add ovirt repo https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm
Install all nodes:
- cockpit-ovirt-dashboard
- gluster-ansible-roles
- vdsm-gluster
- ovirt-host
- ovirt-ansible-roles
-
Thanks .. That worked. now the engine, data, vmstore gluster volumes are
under "engine" control.

I keep going through cycles to get a HCI cluster to deploy.
Gluster is working fine. Standard from HCI wizard:

Their may be aspect of this where HCI engine.. composes bricks of gluster into
engine hosted storage... and then is not able to add hosts into cluster.

What steps did you take to deploy post CentOS 8 Streams deployment? Did you

After several weeks .. I am really in need of direction to get this fixed.
I saw several postings about oVirt package issues but not found a fix.
Thanks for response.
Seems a bit too far into "bleeding edge" .. such that I should kick tires
virtually vs commuting plugins to oVirt +Gluster where upgrades and other
issues may happen. Seems like Alpha stage of (no thin provisioning, issues
with deleting volumes, no export / import ..
These are all storage rich servers.

I think this is the issue. When HCI deployed nodes. and consumed the drives
and setup "engine" "data" and "vmstore"
The GUI was set for "storage" network via hostsnames correctly. And I think,
based on watching replication traffic it is using 10Gb "storage" network. CLI
shows peers on that
I have a network called "Storage" but not called "gluster logical network"
Front end 172.16.100.0/24 for mgmt and vms (1Gb) "ovirtmgmt"
Back end 172.16.101.0/24 for storage (10Gb) "Storage"

there is a "Import VM" tab which
will allow you to import your VMs.
Anyone have idea on how this is done?
I can see .meta and .lease files but not sure how this would be used to
import VMs.
It would be nice to tell it to review current "disk / images" and compare to
what is in library
Thanks for reply.. It really is appreciated.
1) Note about VM import
-> Can you provide details / Example. For me I click on
oVirt-> Compute -> Virtual Machines -> Import
-> Source Option (only ones making any sense would be "Export Domain" rest
are unrelated and KVM one would need xml..

I did upload the iso as image.. but how do you attach it to the VM ? I
assumed that issue was a 4.4 changes / constrain.
It was a miss-interpretation on my part that ISO use was relegated to being
only as a "volume" independent.
As such.. I went back to

Thanks for reply. I read this late at night and assumed the "engine url" meant
old KVM. system .. but this implies the oVirt engine. I then translated your
helpful notes... but likely missing some parameter.
