Re: Trying to add a LUN to a host and use that, instead of Gluster, as the datastore for my VM's.
You can create an NFS on that host and export to itself that local storage... Best Regards, Strahil NikolovOn Oct 9, 2019 07:43, TomK <tomkcpr@mdevsys.com> wrote:
Manged to reverse it through the options. Had to deactivate the custom local cluster.
Now I have my GlusterFS back and want to try and add some local storage to each host under the same DC, Cluster and Storage Domain. So effectively I will have two storage locations. One on my GlusterFS and the other on the local storage I've just defined.
Appears I can't make them coexist with oVirt. Either the host is placed in a separate cluster with local storage, or I move it back to the GlusterFS.
Appears I can't have two usable storage types under one host. Is this correct?
What I'm looking for is in the image and shared earlier.

My storage domain still exists. However I can't activate it. The Manage button is greyed out without clear indication as to why. Difficult to tell what my next move should be.

So I followed this and configured local storage. It had some default names that I changed. It would have been either the default name, or one I choose. In either case it would be a different name then the Gluster storage domain the host was a part of anyway.
Once the process completed for both hosts, I noticed the Gluster volume storage domain was offline and the gluster volume was gone. I can't seem to add that back in anymore. I get:
"Error while executing action DisconnectStorageServerConnection: Error storage server disconnection"
Guessing I can't have local storage in addition to Gluster on the same hosts and available for VM's?
Reason why I need that is that Gluster is slow but provides redundancy and live migration. But I also wanted direct storage for VM's requiring faster IO. So here's my scenario:
host01 /dev/sda OS /dev/sdb 4TB (For Gluster) /dev/sdc 4TB (For Local Storage)
host02 /dev/sda OS /dev/sdb 4TB (For Gluster) /dev/sdc 4TB (For Local Storage)
I would like to have:
1) GlusterFS volume available to oVirt via the two /dev/sdb drives in both physical hosts. 2) Two locally attached LUN's, each separate and local to that physical host.
Is this possible?

I've tried a number of options, including adding LUN's but appears I can only add them to VM's directly but not use them as my datastores instead of GlusterFS.

I take it then theres no way to do so without NFS? Sent from my iPhone

I think you should be able create a gluster volume from the local LUN on each server and use these to create 2 storage domains. They should then be shared storage but not replicated so if a host goes down you will loose that domain. Maybe you will need to alter the fencing policy?
