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.
crm_node output has changed in the latest pacemaker build
[root@virt-144 ~]# crm_node -l
4 virt-145
1 virt-142
3 virt-144
The new build however shows this (including an offline node):
[root@virt-145 ~]# crm_node -l
3 virt-144 member
2 virt-143 lost
1 virt-142 member
4 virt-145 member
We just need to update pcs to split on " " without a limit of 1 split.
Then if there's a 3rd field and it's 'lost', we just ignore that line, otherwise we continue.
To test:
With new pacemaker, two hosts host-600, host-604 (600 is down).
Old pcs:
[root@host-604 pcs]# pcs status nodes pacemaker-id
1 host-600 lost
2 host-604 member
New pcs (with fix):
[root@host-604 pcs]# ./pcs status nodes pacemaker-id
2 host-604
Before Fix:
[root@host-604 ~]# rpm -q pcs
pcs-0.9.143-9.el7.x86_64
[root@host-604 ~]# pcs status nodes pacemaker-id
1 host-600 lost
2 host-604 member
[root@host-604 ~]# pcs status | grep "WARNING: coro"
WARNING: corosync and pacemaker node names do not match (IPs used in setup?)
After Fix:
[root@host-604 ~]# rpm -q pcs
pcs-0.9.143-11.el7.x86_64
[root@host-604 ~]# pcs status nodes pacemaker-id
2 host-604
[root@host-604 ~]# pcs status | grep "WARNING: coro"
[root@host-604 ~]#
