Nir, The run and protect was the line above, I have included it above the rest. My comments about not creating a extra data centre agree with yours. I want: 1 data centre which includes: 1 set of storage domains

What do you mean by "set of storage domains?"

3 hosted engine ha hosts 4 extra hosts

I don't know about hosted engine limitations, but generally a host can be only part of one DC and cluster. So you can have 3 hosts serving as hosted engine nodes, with their own storage, used only for hosted engine, and you can have another DC for vms, using other storage domains. Or you can have one DC, with all the storage domains, and several clusters, one for hosted engine nodes, and one for compute nodes for other vms. In this case all the nodes will have to connect to all storage domains. Pick the setup that fits your needs.

I cannot activate an additional (non ha) host as it errors mounting the gluster hosted engine domain as it does not pass the -t glusterfs. I don't really care if they didn't (as it is only there for the hosted-engine ha hosts) but that does not seem possible. ________________________________________ From: Nir Soffer <nsoffer@redhat.com> Sent: Wednesday, 9 March 2016 6:17 PM To: Bond, Darryl; Ala Hino Cc: users@ovirt.org Subject: Re: [ovirt-users] Adding servers after hosted ending servers fail due to incorrect mount options in vdsm

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.

Please add the logs above the log you posted, with the string "Run and protect, connectStorageServer"

This log contains the arguments received from engine, revealing what is going on. jsonrpc.Executor/4::INFO::2016-03-09 16:05:02,002::logUtils::48::dispatcher::(wrapper) Run and protect: connectStorageServer(domType=7, spUUID=u'00000001-0001-0001-0001-000000000229', conList=[{u'id': u'19fb9b3b-79c1-48e8-9300-d0d52ddce7b1', u'connection': u'ovirt36-h1:/hosted-engine', u'iqn': u'', u'user': u'', u'tpgt': u'1', u'password': '********', u'port': u''}], options=None)

There must be vfs_type parameter here, with the value "glusterfs". Kind of redundant since we have a domType=7, which is glusterfs, but this is the current API, and we must keep it for backward compatibility. The owner of the code sending this value should take a look. Nir

-t glusterfs is missing here

This line can be generated only by the GlusterfFSConnection, used when connecting to gluster storage domain, but this connection type ads the "glustefs" type.

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.

Same storage domains? Maybe you mean same bricks?

You cannot use the same storage domain from different DC. You can create new gluster volume using the same bricks.
