Cause: Temporary location constraint is created by moving the resources Consequence: Warning in `pcs status` command is shown despite the location constraint being already expired Fix: Filter out expired constraints when displaying warning in the `pcs status` command Result: Warning in `pcs status` is not displayed for location constraints that are already expired

Description Nina Hostakova 2022-07-27 14:43:10 UTC
Description of problem:
The new feature of pcs prints out a warning when location constraints are created by moving resources. The warning about existing constraints is displayed in 'pcs status' as well. This warning should not be present in status when the constraint is no longer in effect, i.e. temporary constraints created with --lifetime parameter that are already expired.

Version-Release number of selected component (if applicable):
pcs-0.10.14-1.el8.x86_64

How reproducible:
always

Steps to Reproduce:

# pcs resource move dummy1 lifetime=PT1M
Migration will take effect until: 2022-07-20 15:13:12 +02:00
Warning: Creating location constraint 'cli-ban-dummy1-on-virt-487' with a score of -INFINITY for resource dummy1 on virt-487.
	This will prevent dummy1 from running on virt-487 until the constraint is removed
	This will be the case even if virt-487 is the last node in the cluster

# pcs constraint location
Location Constraints:
  Resource: dummy1
    Constraint: cli-ban-dummy1-on-virt-487

        Expression: date lt 2022-07-20 15:13:12 +02:00

# pcs status | grep "WARNINGS" -A 3
WARNINGS:
Following resources have been moved and their move constraints are still in place: 'dummy1'
Run 'pcs constraint location' or 'pcs resource clear <resource id>' to view or remove the constraints, respectively
