There is no difference.  All servers are able to feed the
configuration information back to the client.  You just need to
specify one.

Hmm, you shouldn't be able to rmmod the module while the pvfs2-client
is running.  The proper shutdown is as follows:

umount /mnt/pvfs2
killall pvfs2-client
(wait 2 seconds for the client to terminate properly)
rmmod pvfs2

Crushes?  Crashes?  Can you provide some more information?  How does
it crash and what was happening at the time?
