Hi,

Will there be a patch or minor release for OSP10 that contains this fix? Or do we have to ask customer to upgrade openstack-cinder to 9.1.3-1.el7ost? 

Thanks.

Hi Andre, 

Added OtherQA as I don't have a VNX system to verify this bug. 
Was asked to set needinfo on you for further verification tracking.

Comment 6 Yue Zhao 2017-06-07 06:45:27 UTC

Not sure if it aligns to RedHat's process, but I don't think you need to verify this bug on VNX system. The fix was already verified before it merged into Cinder upstream. The purpose of the ticket is to confirm the upstream fix is pulled into RedHat distro. Since it's in 9.1.3-1.el7ost, I'm ok to close this ticket. Please correct me if I'm wrong. Thanks.

Comment 7 Tzach Shefi 2017-06-07 10:27:18 UTC

Thanks Yue, 
Based on your comment above, plus checking that patch has landed on my current build openstack-cinder-9.1.4-3.el7ost.noarch,I've verified this bug.
