[ovirt-users] Gluster setup for oVirt

[Jonas]

Hello all

I tried to setup Gluster volumes in cockpit using the wizard. Based on 
Red Hat's recommendations I wanted to put the Volume for the oVirt 
Engine on a thick provisioned logical volume [1] and therefore removed 
the line thinpoolname and corresponding configuration from the yml file 
(see below). Unfortunately, this approach was not successful. My 
solution is now to only create a data volume and manually create a thick 
provisioned gluster volume manually. What would you recommend doing?


Thanks your any input :)

Regards,
Jonas

You can setup gluster volume from scratch via oVirt
Once you add 3 nodes to the cluster - create bricks using the Storage
Devices sub-tab under each host. This will provision and mount the brick
from an unused raw block device on host.
Once the brick directories are mounted - use the New volume dialog to
create the volume
