Fixed In Version: openstack-tripleo-common-5.7.1-0.20170126235054.c75d3c6.el7ost
Doc Type: Bug Fix
Doc Text:
When deleting a node in heat, the deletion command finished and the prompt returned, although the process was still going on in the background. If another command followed immediately, a conflict would occur and the consequent command would fail. The behavior of the process has been changed. Now, the prompt will only return, when the process finishes completely.

Description Dan Macpherson 2016-04-13 03:27:31 UTC 
Description of problem:
When you run "openstack overcloud node delete" it starts a stack update in Heat in the background then drops to the CLI. This could cause stack update collisions if you run another overcloud command immediately after. For example, run "openstack overcloud node delete" then run "openstack overcloud deploy" immediately after. 


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


How reproducible:


Steps to Reproduce:
1. Run "openstack overcloud node delete" and wait to be dropped to the command line
2. Run "openstack overcloud deploy" immediately after
3. Wait for a bit,then run "heat stack-list --show-nested" to see stack with status of "UPDATE_FAILED"

Actual results:
Stack update collisions

Expected results:
Maybe the same behavior as "openstack overcloud deploy" i.e. don't drop the the CLI, but instead show a log of the processes occurring.

Additional info:
I've documented where applicable to wait until the "openstack overcloud node delete" completes, but this might be a good RFE as a safety feature.

+1 It's odd when all the other cmds don't drop back into the cmd line until operation is complete.
Comment 4 Julie Pichon 2016-12-21 12:44:12 UTC 
There seems to already be work on-going to resolve this upstream. I'm updating the bug to match that information and will help with reviews as I can upstream. Brad, please let me know if this isn't ok or it turns out I misunderstood something. Thank you!
Comment 7 Julie Pichon 2017-01-05 15:07:08 UTC 
Patches merged upstream.
Comment 8 Julie Pichon 2017-02-08 13:44:42 UTC 
Checking the current puddle, the fix seems to be present. Updating NVR (hopefully correctly!) and component.

Verified. Deleted a compute node and saw that the workflow env was updated with the new counter.
