Description SATHEESARAN 2017-11-28 16:43:12 UTC
+++ This bug was initially created as a clone of Bug #1518344 +++

Description of problem:
Cockpit provides option to configure bricks exactly the same way on all the nodes. Example is that the brick could be created from sdb on all the nodes.

If the user wanted to make use of sdb from node1, sdc from node2, and sdd from node3. Then this is not possible with the existing cockpit.

Specifically this requirement becomes essential when arbitrated replicate volume is chosen. Arbitrated replicate volume requires the arbiter brick could be placed on the disk which has less storage space.

Version-Release number of selected component (if applicable):

How reproducible:
Not Applicable

Steps to Reproduce:
1. Start with the installation of RHHI deployment
2. Choose arbitrated replicate volume for 'data' and 'vmstore' volume

Actual results:
Cockpit limits the user to create bricks symmetrically on the all nodes. 
If 'sdb' is chosen, bricks are created on 'sdb' on all the nodes

Expected results:
Asymmetric brick configuration should be allowed for users to create bricks on specific disks

Additional info:
With this limitation in place, the users can solve this problem by editing the generated gdeploy configuration. But again this is error prone and hard to edit the generated gdeploy configuration file.

Tested with RHV-4.2.2-6 and cockpit-ovirt-dashboard-0.11.19

Bricks could be created asymmetrically on the 3 hosts. For eg. sdb from host1, sdc from host2, sde from host3 could be used for creating gluster volumes
