cinder (Ubuntu)

Bug Description


Detaching a volume from a nova instance sometimes not removing it from VNX storage group. It is caused by out-of-date cache for in VNX volume driver. Cache needs to be updated with correct info after creating a storage group.
This fix was applied to Ocata and back ported to Newton upstream:
This ticket is a request for merge the upstream fix above to Ubuntu 16.10 (Newton package).

How to Reproduce:
1.Detach a volume from nova instance
2.Use nova and cinder command to confirm the volume is detached.
3.Use NaviSecCli to confirm the LUN is removed from the corresponding storage group.

Actual results:
The LUN is still in the Storage Group after detaching.

Expected results:
The LUN is removed from the Storage Group after detaching.

Thanks for the bug report this looks resonable to me for a future SRU point release into Ubuntu.

Hello Denny, or anyone else affected,

Accepted cinder into yakkety-proposed. The package will build now and be available at in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Thanks for taking this fix. Since a lot of customers are using xenial release. Is it possible to backport this fix to 16.04 as well? Thanks.

This bug is still pending verification for yakkety (and the Ubuntu Cloud Archive for Newton).

Denny Zhao (denny-zhao) wrote :

Sorry for the delayed response and thanks for the reminder. I will try to verify it this week.
If the fix is merged, is there a way for 16.04 customer to apply this fix on their system?

James Page (james-page) wrote :


The fix is in the Cloud Archive for Ocata which targets 16.04; if this is required in Mitaka, then we'll have to look at cherry-picking the fix back to that series as well (not currently in scope for this bug).

This fix has been verified in EMC's test environment on 16.04. Thanks.

This bug needs to be verified on Ubuntu Yakkety and Ubuntu Xenial using the packages in the proposed pocket as described in #2.

Given that bug 1688557 is about a point release update of packages in OpenStack Newton and that James Page indicates that the fix for this bug is included in cinder 9.1.4, were this bug not explicitly referenced in the changelog this fix would have been released given the testing in bug 1688557.

Subsequently, even though the verification for this specific bug was not completed, the release and package version tested do not match the release task here, I am going to go ahead and release cinder to -updates.
