Ovirt is using the default shard file of 64MB and I don't think this is 'small
file' at all.
There are a lot of tunables to optimize Gluster and I can admit it's not an
easy task.
Deadline is good for databases, but with SSDs you should try the
performance of enabled multiqueue and
I’ve tried various methods to improve gluster performance on similar
hardware and never had much luck. Small file workloads were particularly
troublesome. I ended up switching high performance vms to nfs storage and
performance with nfs improved greatly in my use case.

As you will migrate from block-based storage to file-based storage, I think
that you should use the backup & restore procedure.

Hi!
I have banged my head against deploying the ovirt 4.4 self-hosted engine
on Centos 8.2 for last couple of days.
First I was astonished that resources.ovirt.org has no IPv6
connectivity, which made my initial plan for a mostly IPv6-only
deployment impossible.
CentOS was installed from
