Critical What were you trying to do that didn't work?
Use crm_resource to edit meta attributes of a group element inside a master element.
What is the impact of this issue to you?
crm_resource is unable to modify specific parts of CIB. Consequently, 'pcs resource delete' command stops working, as it is utilizing crm_resource to modify CIB.
Please provide the package NVR for which the bug is seen:
pacemaker-2.1.8-508.3e41be73c2.git.el10.x86_64
How reproducible is this bug?:
always, easily
Steps to reproduce
- Have a CIB with the following preamble:
<cib crm_feature_set="3.19.7" validate-with="pacemaker-3.9">
- Put the following resource into CIB:
<master id="gr-clone"> <group id="gr"> <primitive id="d5" class="ocf" type="Dummy" provider="pacemaker"> <operations> <op name="monitor" interval="10s" timeout="20s" id="d5-monitor-interval-10s"/> </operations> </primitive> </group> </master>
- Try to set meta attributes for 'gr' resource:
crm_resource --resource gr --meta --set-parameter target-role --parameter-value Stopped
Expected results
meta attributes are set
Actual results
The command end with an error and meta attributes are not set:
Performing update of 'target-role' on 'gr-clone', the parent of 'gr' crm_resource: Error performing operation: No such object
When run in verbose mode, we can see that CIB has been migrated to a new schema version, which no longer supports master elements:
