Hello,
I think options for mounting the hosted-engine Volume changed in latest
vdsm to support mounting from backup-volfile-servers.
[root@microcloud28 ~]# rpm -qi vdsm
Name : vdsm
Version : 4.17.28
Release : 1.el7
Architecture: noarch
Install Date: Fri 10 Jun 2016 11:17:37 AM CEST
Group : Applications/System
Size : 3828639
License : GPLv2+
Signature : RSA/SHA1, Fri 03 Jun 2016 12:53:20 AM CEST, Key ID
7aebbe8261e8806c
Source RPM : vdsm-4.17.28-1.el7.src.rpm
Now my hosts have problems to mount the Volume. On hosted-engine setup I
configured the (Replica 3) volume to be
"glusterfs.rxmgmt.databay.de:/engine" which ist a Round-Robin DNS to my
gluster hosts and _not_ the DNS-Name of any gluster-brick.
Now VDSM logs:

File "/usr/share/vdsm/storage/mount.py", line 241, in _runcmd
raise MountError(rc, ";".join((out, err)))
MountError: (32, ';Running scope as unit run-13461.scope.\nmount.nfs: an
incorrect mount option was specified\n')
So the mount is tried as NFS which hasn't the option "-o
backup-volfile-servers=3D...".
As a consequence the host is disabled in engine. The only way to get it
up is mounting the volume manually to
/rhev/data-center/mnt/glusterSD/glusterfs.
rxmgmt.databay.de:_engine and activate it manually in Management-GUI.
Should and can I change the hosted_storage entry-point globally to i.e.
"microcloud21.rxmgmt.databay.de" or wouldn't it be better globally that
VDSM uses "-t glusterfs" to try to mount the gluster-Volume regardless
which DNS Name for the gluster-service is used ?
Ovirt is:
ovirt-release36.noarch 1:3.6.6-1
