This error is troubling.  You've got all your servers running, which
is a great start, but until this error goes away, you'll have
difficulty actually using pvfs2.

Can you double check that all your pvfs2-servers the same version?  It
might also be good to re-create the pvfs2 storage spaces (use the -r
option to pvfs2-server, but it will delete all your data).

If you can get pvfs2-ping to the point where it gives no errors, then
it's likely this error will go away.

This looks fine.  prospero, which i take it is not a pvfs2 server,
will not need to run pvfs2-server.  You're running pvfs2-client, but
at this point we're not dealing with the kernel interface so that also
doesn't matter (but will later on)
