Hi Andrew,

Sorry....
My response was late.

        if(do_force) {
                crm_debug("Forcing...");
/*              cib_options |= cib_scope_local|cib_quorum_override; */
                cib_options |= cib_quorum_override;
        }


I confirmed movement with you according to a revision. 
The resource moves well.

Can 1.0 reflect this revision?
Because there is influence else, is it impossible?

Best Regards,
Hideo Yamauchi.
