Description Marios Andreou 2017-03-31 14:46:09 UTC

Description of problem:
The ordering between batch_upgrade_tasks and upgrade_tasks is not being enforced.

For the N..O upgrades workflow [1] the batch_upgrade_tasks are meant to be used to execute those upgrade tasks that should be executed on one node at a time. These are also expected to be run before any of the rest of the upgrade_tasks are executed.

This ordering is currently broken - there is a review out at https://review.openstack.org/#/c/448602/ to fix it.

Filing this bug for more info and as we will need the fix into stable/ocata too

Version-Release number of selected component (if applicable):

This is only noticeable if you are testing the batch upgrade tasks, i.e. upgrading ceph as part of the ansible upgrade steps.

Comment 2 Jaromir Coufal 2017-03-31 21:34:19 UTC

Based on discussion with gfidente:
Impact if not resolved: batch and non-batch tasks might be triggered simultaneously on the same node which might lead into issues during upgrade and fail the whole procedure.

On stable/ocata.

Comment 5 Marius Cornea 2017-04-25 16:23:50 UTC

We can see that all the UpgradeBatch stacks are created/updated before the Upgrade_Step ones. Moving to verified:
