I was able to create the new gluster volume fine, but it’s not 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.

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.
