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 Chris Feist 2020-09-01 18:47:56 UTC 
This is a preliminary proposal to create a pcs command to export all resources as from a pcs command.  (and eventually expanding to include other commands).

For example:

With a cluster with 2 dummy resources (D1 & D2)

# pcs resource export
pcs resource create D1 ocf:heartbeat:Dummy
pcs resource create D2 ocf:heartbeat:Dummy
Comment 1 Reid Wahl 2020-09-02 08:48:12 UTC 
Just an FYI since I don't expect anyone to click it unprompted: https://access.redhat.com/solutions/5364341 notes that pcs cluster cib/cib-push (with appropriate scope option) accomplishes basically the same thing except for printing individual commands.

I see why people might want an export command like this though.

The same verification as for RHEL9 part of this feature (bz2058251) was used to test this bz - bz2058251 comment 8, results were the same.
Marking as VERIFIED for pcs-0.10.13-1.el8
