Description bipin 2018-06-05 10:59:17 UTC

+++ This bug was initially created as a clone of Bug #1586023 +++

Description of problem:
After adding the storage domain in the RHV-M UI, could see one of the storage domains guaranteed space more than total space. The volume size for that domain(data) was 12T , but the guaranteed space seems to be 16T. Have attached the screenshot for the error.


Version-Release number of selected component (if applicable):
ovirt-host-4.2.3-1.el7ev.x86_64
ovirt-hosted-engine-ha-2.2.13-1.el7ev.noarch


How reproducible:
1/1

Steps to Reproduce:
1.Have the HE deployed
2.Add the storage domains
3.Check the guaranteed space


Actual results:
The guaranteed space is more than the total space


Expected results:
The guranteed space should be same as total space

Please provide lsblk output from all 3 nodes, the vdsm logs with the logicalvolume monitoring and the engine.log

Comment 4 Sahina Bose 2018-06-07 18:50:15 UTC

object has no attribute 'glusterLogicalVolumeList' - I see this error, can you check the version of vdsm running on the host?

Comment 5 bipin 2018-06-08 03:47:00 UTC

The vdsm version used is vdsm-4.20.29

Comment 6 bipin 2018-06-22 06:03:40 UTC

Verified the bug in component version vdsm-4.20.31-1.el7ev.x86_64.

Result: Now the Storage Domain using same thin devices have same guaranteed free space. Attaching the screenshot from RHV-M
