Description Steven Hardy 2017-11-29 10:00:31 UTC
Description of problem:

In previous releases, we fixed a problem where the bootstrap node was hard-coded to be the first controller, e.g "0", patch here:

https://review.openstack.org/#/q/I8b1c9538976a1518b220187a0034ad41a738d5a6

previous upstream bug:

https://bugs.launchpad.net/tripleo/+bug/1640449

However this issue has resurfaced in the recently reworked templates which support containers, fixed in this commit/backport upstream:

https://review.openstack.org/#/q/Iaffc66a41edf176dde3b5adf603a9cff6db7aa24

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


How reproducible:
Always

Steps to Reproduce:
1.Deploy an overcloud
2.Attempt to run openstack overcloud node delete on the primary overcloud-controller-0 (e.g due to hardware failure)
3. This will fail because of the hard-coded reference

The only workaround is to edit the templates to replace the hard-coded reference to index/name "0".

Actual results:
Removal of controller-0 is not possible

Expected results:
It should be possible to remove controller-0 via the normal node replacement process.

Additional info:
Upstream backport proposed at https://review.openstack.org/#/c/523822/
