Description Ken Gaillot 2019-06-07 15:36:30 UTC

This was implemented in pacemaker for 8.1, but it appears pcs is filtering the output. crm_resource --clear shows removed constraints, but pcs resource clear still does not.

+++ This bug was initially created as a clone of Bug #1631752 +++

Description of problem:
When running pcs resource clear, I cannot be sure that anything actually happened. It would be good to print out all actions that have taken place.

Example:
[root@tardis-02 /]# pcs constraint ref gitlab-runner-1
Resource: gitlab-runner-1
  colocation-gitlab-runner-1-libvirtd-clone-INFINITY
  location-gitlab-runner-1-tardis-03-INFINITY
  order-libvirtd-clone-gitlab-runner-1-Mandatory
[root@tardis-02 /]# pcs resource move gitlab-runner-1
Warning: Creating location constraint cli-ban-gitlab-runner-1-on-tardis-03 with a score of -INFINITY for resource gitlab-runner-1 on node tardis-03.
This will prevent gitlab-runner-1 from running on tardis-03 until the constraint is removed. This will be the case even if tardis-03 is the last node in the cluster.
[root@tardis-02 /]# pcs constraint ref gitlab-runner-1
Resource: gitlab-runner-1
  colocation-gitlab-runner-1-libvirtd-clone-INFINITY
  location-gitlab-runner-1-tardis-03-INFINITY
  cli-ban-gitlab-runner-1-on-tardis-03
  order-libvirtd-clone-gitlab-runner-1-Mandatory
[root@tardis-02 /]# pcs resource clear gitlab-runner-1

Red Hat Enterprise Linux Server release 7.5 (Maipo)





Version-Release number of selected component (if applicable):
pcs-0.9.162-5.el7_5.1.x86_64

How reproducible:
Always

Steps to Reproduce:
1. see example
2. pcs resource move <resource> && pcs resource clear <resource>
3.

Actual results:
pcs resource clear is silent

Expected results:
pcs resouce clear prints actions it is taking

Additional info:

Pcs merely runs 'crm_resource --resource <resource> --clear' and that does not seem to be providing any output. Ken, are you ok with moving this to pacemaker?

--- Additional comment from Ken Gaillot on 2018-11-13 15:50:02 UTC ---

Yes, that makes sense, done. We can let --quiet keep the current behavior.

Comment 2 Tomas Jelinek 2019-06-10 11:08:39 UTC

This has been done in upstream some time ago: https://github.com/ClusterLabs/pcs/commit/601b765a662f4852d15be72074cff57df1864693 and it has been included in pcs packages since pcs-0.10.1-6.el8
