Description of problem: Currently, when creating a gluster volume, the user has to manually enter the path of the brick in the UI. There is no way to know the list of disks/ logical volumes available or even to prepare the disk to use as a brick. The requirement is to provide this capability from oVirt to ease the administrator's task.
Tested with RHEV 3.6.3.3 and RHGS 3.1.2 RC added to 3.5 cluster compatibility 1. Storage devices are discovered 2. Able to create bricks from that devices 3. Create a volume with the list of available bricks
