Bug Fix

Doc Text:

Cause: Arbiter brick was treated as a data brick. Consequence: Volume physical size was calculated incorrectly Fix: Arbiter was excluded from the guaranteed size calculations. Result: Only data nodes participate in the calculations right now, so results are correct.

Description bipin 2018-06-29 07:45:05 UTC

+++ This bug was initially created as a clone of Bug #1596520 +++

Description of problem:
The guaranteed free space for arbiter volume uses the size of the arbiter brick.
Created a 1*3 arbiter volume.Here the guaranteed free space takes the thinpool size of the 3rd host which has the arbiter brick.

Version-Release number of selected component (if applicable):
ovirt-engine-4.2.4.5-0.1.el7_3.noarch

How reproducible:
100%

Steps to Reproduce:
1.Create a arbiter volume replica
2.Go to the HE 
3.Navigate to storage -> domain
4.Check the Guaranteed space size (Displays the thinp size of the 3rd host)

Actual results:
Uses the arbiter brick size for thinp calculation in guaranteed free space

Expected results:
Should make use of thinp size of non arbiter brick

Comment 2 bipin 2018-07-26 06:08:55 UTC

Verified the bug in ovirt-engine-4.2.5.2.

Steps:
=====
1.Create a arbiter replica volume on a VDO volume using cockpit
2.Once the HE deployment is completed navigate to storage domain
3.The guaranteed free space and free space should be relatively same

Comment 5 starfall 2019-03-08 15:37:33 UTC

I'm running into the exact same problem here with the gluster arbiter is being created on 2nd host, while the arbiter LV is created on the 3rd host. This is on the latest version of ovirt.

ovirt-host.x86_64 - 4.3.1-1.el7

This happened during the original hyperconverged HE ansible deploy as well as during subsequent gluster volume creation from cockpit. VDO was not used in this deployment.

Configuration of the volume in ovirt-engine HE UI -

nde2:/gluster_bricks/data1/data1 (Arbiter)
