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.
When attempting to remove nodes from a running corosync cluster I get a segfault. Below are the commands/output that I'm running. (cluster is udpu)
[root@rh7-1 ~]# rpm -q corosync
corosync-2.0.1-3.el7.x86_64
I've got a 3 node cluster running pacemaker/corosync. I shutdown pacemaker and corosync on the 3rd node (rh7-3) and try to remove it on another node from the running corosync and I end up getting a segfault. Here are the commands I'm running.
Before rh7-3 shutdown:
[root@rh7-1 ~]# corosync-quorumtool -l
Membership information
----------------------
Nodeid Votes Name
3 1 rh7-3
2 1 rh7-2
1 1 rh7-1
After shutdown:
[root@rh7-1 ~]# corosync-quorumtool -l
Membership information
----------------------
Nodeid Votes Name
2 1 rh7-2
1 1 rh7-1
[root@rh7-1 ~]# corosync-cmapctl | grep nodelist
nodelist.local_node_pos (u32) = 0
nodelist.node.0.nodeid (u32) = 1
nodelist.node.0.ring0_addr (str) = rh7-1
nodelist.node.1.nodeid (u32) = 2
nodelist.node.1.ring0_addr (str) = rh7-2
nodelist.node.2.nodeid (u32) = 3
nodelist.node.2.ring0_addr (str) = rh7-3
[root@rh7-1 ~]# corosync-cmapctl -d nodelist.node.2.ring0_addr nodelist.node.2.nodeid
Can't delete key nodelist.node.2.ring0_addr. Error CS_ERR_LIBRARY
Can't delete key nodelist.node.2.nodeid. Error CS_ERR_LIBRARY
Then corosync segfaults. I get these messages in /var/log/messages:
