Description SATHEESARAN 2018-02-21 13:02:30 UTC

Description of problem:
-----------------------
Firstly there is already a issue(BZ 1547450), where gdeploy config file is generated to have multiple VDO volumes.If that issue is fixed, the logical size of VDO volume should be sum of sizes of bricks and multiplied by 10

Currently, the size of one of brick is made as the logical size of VDO volume.

Note: For VM usecase on VDO, the recommended physical to logical size ration is 10:1

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
cockpit-ovirt-0.11.11

How reproducible:
-----------------
Always

Steps to Reproduce:
--------------------
1. Start RHHI installation from cockpit, using 'Hosted Engine with Gluster'
2. Proceed with enabling dedupe and compression on all the bricks

Actual results:
---------------
VDO logical size is set to the logical size of one of the brick

Expected results:
-----------------
gdeploy configuration file should contain logical size of the VDO volume equal to 10*(sum of size of all the bricks)

As the dependent bug is moved to ON_QA, moving this bug to ON_QA

Comment 5 bipin 2018-04-18 13:07:05 UTC

Verified the bug in the below component version's successfully.

Component versions's:
gdeploy-2.0.2-23.el7rhgs.noarch
cockpit-ovirt-dashboard-0.11.21-1.el7ev.noarch

Steps:
1. Install VDO 
2. Start the gluster deployment via cockpit UI and check the compression and deduplication tab.
3. Could see the logical size is equal to 10 times the sum of bricks

Result:
Please find the attached screenshot of the verification
