Do you plan to implement such locking RA?

I don't understand how to configure that. If I use on_fail=fence, 
Pacemaker will fence the node? How to tell Pacemaker to fence resource?

Could please explain how to configure such collocation? Or it is not
yet possible?

How to order resource fencing? OCF RA should support resource fencing.
Which resources OCF can do that? (GNBD, iSCSI, ...). Resources which
support locking I guess?


Thanks for the help.
