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-2.1.5-9.el9_2.3
Doc Type: Bug Fix
Doc Text:
Cause: A node's attribute manager writes all its transient node attributes from memory to the CIB after winning the election for attribute writer, even if its node has requested shutdown. Consequence: If a node is DC, requests shutdown, and wins the attribute writer election after its controller has left the cluster but before its attribute manager has left, it can write out its shutdown attribute to the CIB. The next time it rejoins the cluster, it will be immediately shut down. Fix: A node's attribute manager should not write out its attributes after winning an election if shutdown has been requested for its node. Result: A leaving DC node does not have an unexpected shutdown the next time it rejoins.
