At the very least you should make sure to apply the gluster virt profile to vm volumes. This can also be done using optimize for virt store in the ovirt GUIĀ

Hey folks,

quick question. For running Gluster / oVirt I found several places, some
outdated (ovirt docs), gluster Mailinglists, oVirt Mailinglists etc that
recommend different things.

Here is what I found out/configured:

features.barrier: disable
features.show-snapshot-directory: on
features.uss: enable
cluster.data-self-heal-algorithm: full
cluster.entry-self-heal: on
cluster.data-self-heal: on
cluster.metadata-self-heal: on
cluster.readdir-optimize: on
transport.address-family: inet
storage.fips-mode-rchecksum: on
nfs.disable: on
performance.client-io-threads: off
network.remote-dio: off
performance.strict-o-direct: on
client.event-threads: 16
cluster.choose-local: true
snap-activate-on-create: enable
auto-delete: enable

Would you agree or change anything (usual vm workload).

Thanks! o/
And keep healthy.
