[ovirt-users] Adding servers after hosted ending servers fail due to incorrect mount options in vdsm

[Bond, Darryl]

I have a 3 node 3.6.3 hosted engine cluster (Default) with a number of VMs. The hosted engine is stored on gluster.

Adding an additional server to the Default cluster that isn't a hosted-engine ha server fails.

Looking at the vdsm.log, the host attempts to mount the gluster as NFS with the gluster options which fails.

    raise MountError(rc, ";".join((out, err)))
MountError: (32, ';Running scope as unit run-18808.scope.\nmount.nfs: an incorrect mount option was specified\n')

I noticed the hosted-engine servers perform the same mount but pass the -t glusterfs correctly.

A bug or am I doing something wrong??

I do not want to create a new datacentre without the hosted engine storage as I want to use the same storage domains.

Regards
Darryl
