[Linux-HA] HA failover script

just a quick question for my understanding. During a failover, Heartbeat
executes its failover script, which, at my site, stops NFS, NFS lockd
and umounts the filesystems.
Unfortunally I get 'filesystem busy' when it tries to umount the fs.
I googled a bit and found a discussion about sending a SIGKILL signal to
the kernel lockd thread for releasing the locks, but I am stopping the
lockd before I try to umount the filesystem.
Now, I got the impression the failover script is executing the commands
but is not waiting for the result of it. Which means NFS is still in
progress of stopping while Heartbeat tries to umount the filesystem.
This would explain the 'device busy' message for me, because NFS is not
yet stopped fully at that time.
Do I am right ? Other ideas ?
Thnx in advance,
