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. jsonrpc.Executor/6::DEBUG::2016-03-09 15:10:01,022::fileUtils::143::Storage.fileUtils::(createdir) Creating directory: /rhev/data-center/mnt/glusterSD/ovirt36-h1:_hosted-engine mode: None jsonrpc.Executor/6::DEBUG::2016-03-09 15:10:01,022::storageServer::357::Storage.StorageServer.MountConnection::(_get_backup_servers_option) Using bricks: ['ovirt36-h1', 'ovirt36-h2', 'ovirt36-h3'] jsonrpc.Executor/6::DEBUG::2016-03-09 15:10:01,022::mount::229::Storage.Misc.excCmd::(_runcmd) /usr/bin/taskset --cpu-list 0-11 /usr/bin/sudo -n /usr/bin/systemd-run --scope --slice=vdsm-glusterfs /usr/bin/mount -o backup-volfile-servers=ovirt36-h2:ovirt36-h3 ovirt36-h1:/hosted-engine /rhev/data-center/mnt/glusterSD/ovirt36-h1:_hosted-engine (cwd None) jsonrpc.Executor/6::ERROR::2016-03-09 15:10:01,042::hsm::2473::Storage.HSM::(connectStorageServer) Could not connect to storageServer Traceback (most recent call last): File "/usr/share/vdsm/storage/hsm.py", line 2470, in connectStorageServer conObj.connect() File "/usr/share/vdsm/storage/storageServer.py", line 236, in connect six.reraise(t, v, tb) File "/usr/share/vdsm/storage/storageServer.py", line 228, in connect self._mount.mount(self.options, self._vfsType, cgroup=self.CGROUP) File "/usr/share/vdsm/storage/mount.py", line 225, in mount return self._runcmd(cmd, timeout) File "/usr/share/vdsm/storage/mount.py", line 241, in _runcmd 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.
