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.
Pacemaker supports tagging of XML elements:
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#_tagging_configuration_elements
This will be important for pcs primarily for nodes and resources, because tagging is expected to be part of the solution for Bug 1300597 and Bug 1300604. The idea is that the user will be able to tag certain nodes and/or resources, then use (not yet implemented) options to crm_mon to display the status of just those.
An example of how it might eventually work:
pcs resource tag myrsc1 special
pcs resource create myrsc2 Dummy --tag special
pcs status --resources=special # shows status of myrsc1 and myrsc2 only
This bz is just for the tagging functionality, which is already supported by pacemaker. A separate bz will be opened for the pcs status functionality once the crm_mon interface is finalized.
I can imagine tagging coming in handy in other situations in the future. Pacemaker implements tags mainly for UI use, so feel free to use tags elsewhere in pcs for any purpose.
FYI, because tags are XML IDs, they are guaranteed to be unique with respect to resource names and node IDs (sadly, not node names). That gives you the option of accepting tag names wherever a resource name can be used, rather than requiring a special syntax in that situation.

This feature is unlikely to be implemented in RHEL 7 due to its high complexity and demand on resources. Since there is already a RHEL 8 bz for the same feature, I am closing this as a duplicate.
