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.

Doc Type: Enhancement
Doc Text:
.Enhancements to the `pcs property` command The `pcs property` command now supports the following enhancements: * The `pcs property config --output-format=` option ** Specify `--output-format=cmd` to display the `pcs property set` command created from the current cluster properties configuration. You can use this command to re-create configured cluster properties on a different system. ** Specify `--output-format=json` to display the configured cluster properties in JSON format. ** Specify `output-format=text` to display the configured cluster properties in plain text format, which is the default value for this option. * The `pcs property defaults` command, which replaces the deprecated `pcs property --defaults` option * The `pcs property describe` command, which describes the meaning of cluster properties.

Description Tomas Jelinek 2023-02-01 12:43:21 UTC 
+++ This bug was initially created as a clone of Bug #2163914 +++

This is a part of a long term goal to export the whole cluster configuration in form of pcs commands which, when run, recreate the same configuration.

This particular BZ is focused on cluster properties configuration.

As discussed, 'pcs property config' text output should not change in late RHEL8 release.
