Thanks, the issue is here:

Dec 21 19:40:53 ovirt-node-03 etc-glusterfs-glusterd.vol[1079]: [2015-12-22
00:40:53.496410] C [MSGID: 106002]
[glusterd-server-quorum.c:351:glusterd_do_volume_quorum_action]
0-management: Server quorum lost for volume vmdata. Stopping local bricks.
So at that point gluster lost its quorum and the fail system got read-only.
On the getStorageDomainsList VDSM internally raises cause the file-system
is read only:

But instead of reporting a failure to hosted-engine-setup, it reported a
successfully execution where it wasn't able to find any storage domain
there ( this one is a real bug, I'm going to open a bug on that, can I
attach your logs there? ):

And so, cause VDSM doesn't report any existing storage domain,
hosted-engine-setup assumes that you are going to deploy the first host and
so your original issue.
