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.

Fixed In Version: pacemaker-2.1.2-4.el8_6.5
Doc Type: Bug Fix
Doc Text:
Cause: OCF resource agent metadata actions block the controller, and crm_node queries now perform controller requests. Consequence: If an agent's metadata action calls crm_node, it will completely block the controller for 30 seconds until the action times out, possibly causing other actions to fail and the node to be fenced. Fix: The controller now performs metadata actions asynchronously. Result: Agent metadata actions can call crm_node without problems.

Comment 1 Ken Gaillot 2022-09-20 19:51:25 UTC
Fixed in upstream main branch as of commit bc852fe3

Comment 2 Chris Lumens 2022-10-12 14:59:21 UTC
Steps to reproduce are in https://bugzilla.redhat.com/show_bug.cgi?id=2121852#c12.  Make sure to modify the Dummy resource agent on the same node that it will execute on (so, either have just a one node cluster or modify it on all nodes to be safe).  Start the cluster and add the Dummy resource.  You'll see in the logs that it takes a while before it times out and logs the error message, but the resource will still be created.  Stop the cluster and start it again with the new resource.  You'll see that it takes a long time to start up and that "crm_node -l" is in the process list.

Update to the new packages.  Start the cluster again and you'll see it start up normally.
