[Pacemaker] want resource A to start successfully (completely) then start B

[Aaditya kumar]

Hi all,
        AFAIK in resource ordering order(A,B)
start A is invoked before start B.

BUT my situation demands that
NOT ONLY start A is invoked before start B
BUT ALSO start A complete successfully (return rc=0) then and only then lrmd
should invoke start B.

In my logs the resources are started as they should be BUT second resource
dosent WAIT FOR first resource's start operation to return .

I am using mysql on nfs mount .
nfs mount is invoked before mysql BUT mysql dosent wait for nfs mount to
finish and mysql dosent start (rc = 6 , resource not configured, coz the
data dir is nfs mount which
is not mounted yet)

IS THERE A WAY to WAIT for first successful start before starting second
resource ?
