Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
In rhel6 cluster we could use "fence_node -S <nodename>" to get status from fence device used by a cluster node. This help to determine if the configuration options used for fence device was correct. I do not believe a similar behavior exists in RHEL 7 or RHEL 8.

https://access.redhat.com/solutions/18803
I believe we should open an RFE to request a similar option in RHEL 8. For example:
# stonith_admin -S <nodename>
or
# pcs stonith debug-monitor <stonith id>
The command returns status output and if debug enabled, then print debug information to see why failed.
FYI pacemaker already has this capability with "stonith_admin --query <device-id>". It will run the device's "monitor" action, and if that fails, it will also run the device's "list" action (not sure why).
I'm assuming, based on the description, that the goal is more for the status of a particular fence device, without regard to any node name. The distinction is that in pacemaker, a node might be fenced by multiple fence devices -- which may be an "and" or "or" type of situation. So going by node name would be more complicated and require a new stonith_admin option. If we're just interested in a device, a pcs wrapper is all we need.

I should point out the current limitations: it will only work when run on a node that is "running" the fence device; and it does not output anything, it just returns a status code.
