[ClusterLabs] pcs: how to properly unset a value for resource/stonith? [Was: (no subject)]

[ArekW]

Hi, Thank you for setting subject. I confirm that the parameter can be
disabled. The only issue is that sometimes thete is a "zombie" message
in logs like I shown before:
Jul 20 07:14:11 nfsnode1 stonith-ng[11097]: warning: fence_vbox[3092]
stderr: [ WARNING:root:Parse error: Ignoring option 'verbose' because
it does not have value ]
