Open Stack

Marcus,

Don’t turn off ci, because then you could miss another regression.

Instead, simply exclude that test case:
e.g.
export DEVSTACK_GATE_TEMPEST_REGEX="^(?=.*tempest.api.volume)(?!.*test_snapshots_actions).*"

Subject: [openstack-dev] [cinder] [Third-party-announce] Cinder Merged patch broke HDS driver

Hi folks,

This weekend, the patch "Snapshot and volume objects" (https://review.openstack.org/#/c/133566) was merged and this one broke our HDS HBSD driver and the respective CI.

When CI tries to run tempest.api.volume.admin.test_snapshots_actions the following error is shown:

2015-03-04 14:00:34.368 ERROR oslo_messaging.rpc.dispatcher [req-c941792b-963f-4a7d-a6ac-9f1d9f823fd1 915289d113dd4f9db2f2a792c18b3564 984bc8d228c8497689dde60dc2b8f300] Exception during messag

Before merging the patch, the CI ran successfully on Patchset,38 (http://177.84.241.119:10000/66/133566/38/silent/hitachi-hbsd-iscsi/17ee25e/) which already changed the files involved in this bug. Is it possible to CI run the tempest tests on Devstack with no patch (triggered by Zuul) applied? The CI didn't run the latest Patchset (41), because we had an infrastructure problem (power failures) during the weekend and the beginning of the week.

I checked the patch merged and I saw that it has changed a lot of snapshots files. In some files the "snapshot_metadata" was removed and replaced to "metadata". I think the best approach is to fix the driver, but until the bug is not fixed and reviewed, the Cinder CI will be offline. Could you guys give an extra priority for review this bug fix when I submit the patch, once it was working (the CI was in checking mode) before the patch merged?
