Description SATHEESARAN 2019-06-25 09:01:29 UTC 
Description of problem:
-----------------------
VDO works as 512e device as 4KN support was not available earlier.
4KN support will be available with the latest sanlock package and now the VDO option to emulate 512 byte device, can be safely removed.

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
cockpit-ovirt-dashboard-0.13.2

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

Steps to Reproduce:
-------------------
1. Remove the VDO option to emulate 512

Actual results:
----------------
VDO has an option to emulate 512

Expected results:
-----------------
VDO need not emulate 512
Comment 1 SATHEESARAN 2019-08-07 14:02:59 UTC 
This bug had to be targeted to RHV 4.3.7, as there are other issues with 4KN support and so VDO had be still do 512e
Comment 2 SATHEESARAN 2019-10-03 12:43:37 UTC 
As discussed in RHHI-V Program meeting, support for 4KN devices are planned for RHV 4.3.8
Targeting this bug for RHV 4.3.8
Comment 3 SATHEESARAN 2020-01-07 09:10:05 UTC 
I see that all the patches are merged. But still this bug is on MODIFIED state ?
Why was there no new build made for cockpit-ovirt-dashboard ?

@sandro, can you help ?
Comment 4 Sandro Bonazzola 2020-01-07 12:56:35 UTC 
We need a build here. I'll ask Gal to do one.
Comment 6 SATHEESARAN 2020-01-09 10:02:21 UTC 
Tested with cockpit-ovirt-dashboard-0.13.9

When the gluster-inventory.yml file is generated with VDO enabled,
emulate512 is set to 'off'
