Description Jan Provaznik 2015-06-26 10:03:29 UTC

Description of problem:
UCLI "overcloud deploy" command supports using heat templates directly instead of using tuskar. There is no this option for "overcloud node delete" command (tuskar is used).

Comment 3 chris alfonso 2015-06-26 17:40:08 UTC

We need to document the workaround using heat directly.

Comment 4 Andrew Dahms 2015-06-29 04:34:36 UTC

Assigning to Dan for review.

Comment 5 Jan Provaznik 2015-07-08 14:05:02 UTC

Once this patch is merged https://review.openstack.org/#/c/199576/, doing node deletion manually is quite simple:

1) create an extra environment file which specifies node indexes to be removed, for example to remove node "overcloud-compute-0" the file should look like this:
$ cat /home/stack/nodes-removal.yaml
parameters:
  ComputeRemovalPolicies:
    [{'resource_list': ['0']}]

2) re-deploy overcloud with decreased number of nodes and the extra env file:
$ openstack overcloud deploy  --use-tripleo-heat-templates --compute-scale 1 -e /home/stack/removal.yaml

Comment 6 Jan Provaznik 2015-07-20 12:07:56 UTC

"overcloud node delete" command was improved to support tht directly:

documentation patch which describes deleting node both with and without tuskar is here:

Looks good to me; moving to VERIFIED.
