Thanks for this, I'm currently trying to debug my config, when I try
to mount ONE of the servers 24 bricks, it's only showing capacity like
it's mounting ONE of the bricks, logs error is:

[2010-05-03 11:18:35] W [posix.c:246:posix_lstat_with_gen] posix1:
Access to /mnt/data01//.. (on dev 16771) is crossing device (2257)

What is this telling me?  I'm looking at just dropping back to
mirroring 2 servers, and replicating from there, then try against all
6.  I'll post my config in a bit.

Thanks
