[Pacemaker] NFS server shutdown issue

[Judd Tracy]

It is a weird issue.  Redhat kills the nfs daemons with a kill -2 in their
init script.  But when pacemaker starts the nfs daemons the only way to kill
the daemons is a kill -9.  I don't have a clue what pacemaker is doing that
would cause this behavior.

As far as the mysql order constraint since the file system is in the group
mysql won't it be brought after the drbd master is promoted?  And don't the
members of the group get started in order?  I am a newbie so please correct
me if I am wrong.
