Hi Ilya,

This issue has previously been reported against Red Hat Enterprise Virtualization. It has been classified as a "request for enhancement" there - and will be prioritised as such for a future release.

Thanks for your report!

there is using 4k mode, and being able to work with them which iirc was already fixed in a later version than node you are using.

We do not yet support using devices with a logical block size > 512B

Would you be so kind as to provide an update on this bug?

My customer needed a link to our official documentation showing that we can't work with native 4k devices.  I provided this link

We are looking to provide this support via Cinder, where RHV is not a part of the storage datapath.

Comment 28 Sandro Bonazzola 2019-01-28 09:43:49 UTC
This bug has not been marked as blocker for oVirt 4.3.0.
Since we are releasing it tomorrow, January 29th, this bug has been re-targeted to 4.3.1.

This is dependent on Bug 1592916 targeted for 4.3.1

Comment 32 Sandro Bonazzola 2019-03-12 12:40:57 UTC
4.3.0 has been already released, automatically re-targeting to 4.3.3 for re-evaluation
