[ovirt-users] ovirt 3.6 and gluster arbiter volumes?

[Arik Mitschang]

Hi ovirt-users,

I have been working on a new install of ovirt 3.6 hosted-engine and ran
into difficulty adding a gluster data storage domain to host my VMs. I
have 4 servers for gluster (separate from vm hosts) and would like to
have the quorum enforcement of replica 3 without sacrificing space. I
created a gluster using

 replica 3 arbiter 1

That looks like this:

 Volume Name: arbtest
 Type: Distributed-Replicate
 Volume ID: 01b36368-1f37-435c-9f48-0442e0c34160
 Status: Stopped
 Number of Bricks: 2 x 3 = 6
 Transport-type: tcp
 Bricks:
 Brick1: t2-gluster01b:/gluster/00/arbtest
 Brick2: t2-gluster02b:/gluster/00/arbtest
 Brick3: t2-gluster03b:/gluster/00/arbtest.arb
 Brick4: t2-gluster03b:/gluster/00/arbtest
 Brick5: t2-gluster04b:/gluster/00/arbtest
 Brick6: t2-gluster01b:/gluster/00/arbtest.arb
 Options Reconfigured:
 nfs.disable: true
 network.ping-timeout: 10
 storage.owner-uid: 36
 storage.owner-gid: 36
 cluster.server-quorum-type: server
 cluster.quorum-type: auto
 network.remote-dio: enable
 cluster.eager-lock: enable
 performance.stat-prefetch: off
 performance.io-cache: off
 performance.read-ahead: off
 performance.quick-read: off
 performance.readdir-ahead: on

But adding to gluster I get the following error:

 "Error while executing action AddGlusterFsStorageDomain: Error creating
 a storage domain's metadata"

I guess my question really is, are volumes like this supposed to be
supported in ovirt 3.6? If so, then this looks like some bug to me and I
will file a report.

Here are versions of main components I am using:

 ovirt-engine-3.6.0.3-1.el7.centos.noarch
 glusterfs-3.7.6-1.el7.x86_64
 vdsm-4.17.10.1-0.el7.centos.noarch

Thanks,
