Comment 10 Gregory Charot 2019-07-10 09:45:07 UTC

The missing patch got merged upstream and we can now proceed with the 13 backport with a z8 target which should be available around end of august / september timeframe.

Hot fixes are meant to provides urgent fixes not feature backports.

Verified on:
openstack-cinder-12.0.7-5.el7ost

Ran full manual test plan, basic work flow is mostly OK. 

Found 3 bugs: 
RO volume aren't RO on all instance, this is a problem but it's a backport TP plus I don't expect many MA RO volumes OK to pass.

Openstack client attach bz:

Despite all these 3, the first being the most serious one
IMHO it's still OK to verify as tech preview backport.
