[Dovecot] Dovecot + DRBD/GFS mailstore

[Guy]

Hi guys,

I'm looking at the possibility of running a pair of servers with
Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or
other clustered FS) for the mail storage and ext3 for the root drive.

I'm currently using maildrop for delivery and Dovecot imap/pop3 with
the stores over NFS. I'm looking for better performance but still
keeping the HA element I have now with shared storage over NFS.

Has anyone had experience with a setup like the one I'm suggesting?
What was performance like with Dovecot using GFS?

Thanks
Guy
