Ok, setting 'gluster volume set data_fast4 network.remote-dio on' allowed me to
create the storage domain without any issues.I set it on all 4 new gluster volumes and the
storage domains were successfully created.
I have created bug for
that:https://bugzilla.redhat.com/show_bug.cgi?id=1711060
If someone else already opened - please ping me to mark this one as duplicate.

I tried adding a new storage domain on my hyper converged test cluster running Ovirt

able to add the gluster storage domain (as either a managed gluster volume or directly
entering values). The created gluster volume mounts and looks fine from the CLI. Errors in

The direct I/O check has failed.
So something is wrong in the files system.
To confirm, you can try to do:
dd if=/dev/zero of=/path/to/mountoint/test bs=4096 count=1 oflag=direct
This will probably fail with:dd: failed to open '/path/to/mountoint/test': Invalid
argument
If it succeeds, but oVirt fail to connect to this domain, file a bug and we will
investigate.

Yep, it fails as expected. Just to check, it is working on pre-existing volumes, so I
poked around at gluster settings for the new volume. It has network.remote-dio=off set on
the new volume, but enabled on old volumes. After enabling it, I’m able to run the dd
test:
[root@boneyard mnt]# gluster vol set test network.remote-dio enablevolume set:
success[root@boneyard mnt]# dd if=/dev/zero of=testfile bs=4096 count=1 oflag=direct1+0
records in1+0 records out4096 bytes (4.1 kB) copied, 0.0018285 s, 2.2 MB/s
I’m also able to add the storage domain in ovirt now.
I see network.remote-dio=enable is part of the gluster virt group, so apparently it’s not
getting set by ovirt duding the volume creation/optimze for storage?
