It should work as ovirt sees it as a regular domain, cephFS will
probably work too

Just tried to setup Ceph hyperconverged

1. Installed oVirt NG 4.4.4 on a machine ( partitioned to leave space for Ceph )

2. Installed CephAdm : https://docs.ceph.com/en/latest/cephadm/install/

3. Enabled EPEL and other required repos.

4. Bootstrapped ceph cluster

5. Created LV on the partitioned free space

6. Added OSD to ceph cluster

7. Added CephFS

8. Set min_size and size to 1 for osd pools to make it work with 1 OSD.

All ready to deploy Self hosted engine from Cockpit

1. Started Self-Hosted engine deployment (not Hyperconverged)

2. Enter the details to Prepare-VM.

3. Prepare-VM successful.

4. Feeling excited, get the cephfs mount details ready.

5. Storage screen - There is no option to use POSIX storage for Self-Hosted. Bummer.

Is there any way to work around this?

I am able to add this to another oVirt Engine.

Thanks,

Shantur

Not sure, it could work, but it hasn't been tested and it's likely you
are going to be the first to try it
