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.

Cause: The user sets the trace_ra and trace_file resource options. Consequence: Pcs exits with an error message saying the options are not defined for the resource and the user should use the --force flag to set them. Fix: Add the trace_ra and trace_file options to allowed options. Result: The user is able to set the trace_ra and trace_file options without using the --force flag.

Description Jan Pokorný [poki] 2016-12-07 12:12:07 UTC 
The attribute in question is supported since 3.9.5 release of
resource agents:

http://lists.linux-ha.org/pipermail/linux-ha/2013-February/046461.html
https://github.com/ClusterLabs/resource-agents/commit/e77e007dd3f30aba87cd7ddee62a7360a36ddd36#diff-deef7019e28edd811e858a1d7283095bR759

meaning the support is present in RHEL 6.6+ and 7.0+.


Currently:

# pcs resource create mydummy3 ocf:heartbeat:Dummy trace_ra=1
> Error: resource option(s): 'trace_ra', are not recognized for
> resource type: 'ocf:heartbeat:Dummy' (use --force to override)
Comment 2 Tomas Jelinek 2016-12-12 14:53:23 UTC 
Note the attribute is called OCF_RESKEY_trace_ra in resource agents sources (see http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#_open_cluster_framework for details)

It looks like the best thing to do is to add the trace_ra attribute to resource agent attributes after reading them from metadata. We only want to do this for ocf:pacemaker and ocf:heartbeat agents and only if the trace_ra is not defined in metadata already.
