[Pacemaker] About specifications of on-fail="block".

Hi,

I compared movement in a version of pacemaker about this problem.

 * 1.0.9-74392a28b7f31d7ddc86689598bd23114f58978b

[root at srv02 ~]# crm_mon -1

     UmIPaddr   (ocf::heartbeat:Dummy2):        Started srv01 (unmanaged) FAILED

Failed actions:
    UmIPaddr_stop_0 (node=srv01, call=9, rc=1, status=complete): unknown error

In the old version, on-fail=block seems to work definitely somehow or other.

The next change influences the difference of the movement.

 * http://hg.clusterlabs.org/pacemaker/stable-1.0/rev/6bf91e9195fe

Is this revision right?

I do not understand contents of the bugs(lf#1959) well, but wish on-fail=block works in the same way
as the past.

Best Regards,
Hideo Yamauchi.
