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.

Description Tomas Jelinek 2015-11-25 11:58:06 UTC
Currently pcsd stores one address per node for remote clusters' nodes. We should add possibility to specify multiple addresses for a node and use them if the node is unaccessible using the first address.

Issues to think about:
* authorization to different addresses of a node

Comment 2 Tomas Jelinek 2018-11-13 09:20:15 UTC
This requires a major overhaul of code related to node to node communication and authentication. It has partially been done in pcs-0.10 branch, so it is possible to follow up with this functionality there (bz1649255). The pcs-0.10 branch cannot be included in RHEL7 as it does not support Corosync 2.x and Pacemaker 1.x. Backporting to pcs-0.9 will not happen as there are fundamental changes which are not compatible with pcs-0.9.
