RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Cause:
User tries to delete a remote node resource which is referenced in constraints.
Consequence:
The resource is not deleted and an error message is displayed stating the resource can not be deleted as it is referenced in constraints.
Fix:
When deleting a resource, remove constraints referencing the resource properly.
Result:
The remote node resource is deleted.

I'm unable delete resource with pcs when I configure constrained VirtualDomain resource follows:
[root@reno-01 x86_64]# pcs resource create vm-guest01 VirtualDomain hypervisor=lxc:/// config=/root/lxc/lxc-01.xml force_stop=true meta remote-node=lxc-01
[root@reno-01 x86_64]# pcs constraint location vm-guest01 prefers reno-01
[root@reno-01 x86_64]# pcs constraint show --full
Location Constraints:
Resource: vm-guest01
Enabled on: reno-01 (score:INFINITY) (id:location-vm-guest01-reno-01-INFINITY)
Ordering Constraints:
Colocation Constraints:
Trying to delete the resource:
[root@reno-01 x86_64]# pcs resource delete vm-guest01
Attempting to stop: vm-guest01...Stopped
Removing Constraint - location-vm-guest01-reno-01-INFINITY
Deleting Resource - vm-guest01
Error: unable to remove resource: vm-guest01, it may still be referenced in constraints.
Reproducible: Always
Steps to Reproduce:
1. setup cluster
2. setup VirtualDomain resource configured as remote-node
pcs resource create vm-guest01 VirtualDomain hypervisor=lxc:/// config=/root/lxc/lxc-01.xml force_stop=true meta remote-node=lxc-01
3. put some constraint e.g. location constraint:
pcs constraint location vm-guest01 prefers reno-01
4. Try to delete VirtualDomain resource
pcs resource delete vm-guest01
5. See error message
Actual Results:
pcs unable to delete the resource
Expected Results:
pcs delete the resource
It happens always when parameter 'meta remote-node=<hostname>' is configured.
In configuration without this parameter are resource and its constraint(s) deleted successfully.
