      What were you trying to do that didn't work?

      I tried to remove the stonith devices and stop the cluster, so I could setup sbd.

      Please provide the package NVR for which bug is seen:

      since pacemaker-2.1.6-7.el9.x86_64

      How reproducible:

      Sometimes, 50% chance

      Steps to reproduce

      1.  setup two node cluster
      2.  check out which node is a DC
      3.  on a DC node: remove the stonith devices and stop the cluster ( 
        pcs stonith delete fence-virt-252; pcs stonith delete fence-virt-253; pcs cluster stop --all

        )

      Expected results

      Stonith devices are deleted, cluster stops.

      Actual results

      Cluster is stuck while stopping:

      [root@virt-253 ~]# pcs stonith delete fence-virt-252; pcs stonith delete fence-virt-253; pcs cluster stop --all
Attempting to stop: fence-virt-252... Stopped
Attempting to stop: fence-virt-253... Stopped
virt-252: Stopping Cluster (pacemaker)...

[root@virt-253 ~]# pcs status --full
Cluster name: STSRHTS14392

WARNINGS:
No stonith devices and stonith-enabled is not false

      After 15 minutes when cluster is stuck (`cluster-recheck-interval` I assume) cluster finally stops.

      I created a crm_report from the incident and attached it. The cluster got stuck on the stop action around Oct 13 13:15
