I don't use jet GlusterFS for IMAP/POP storage for all domains I host. Only a small subset of the domains I host have GlusterFS for IMAP/POP but so far it works without issues and I will soon or later migrate the other domains to be on GlusterFS as well.

The thread moved on and no one seemed to bite, but I also have watched 
glusterfs for a long while now and been very attracted by the basic 
principle. I would be very interested to hear more about how it's worked 
out for you?  Got any benchmarks, perhaps comparing against local 
storage and vs NFS?

It seems intuitively very appealing to use something heavily distributed 
in the style of gluster/mogile for the file data, and something fast 
(like local storage) for the indexes.  Perhaps even dovecot proxying 
could be used to help force users onto a persistent server to avoid 
re-creating index data...

For smaller setups it would be appealing to find something simpler than 
DRBD for a two server active/active setup (eg both servers acting as 
both storage & imap and failover for each other)
