Hi,
The cyrus mail server mailling lists have some mails reporting success in
a similar scenario. Some claim to have made HA cyrus mail servers with a SAN
behind, removing some locking issues with BerkeleyDB. Check out
http://news.gmane.org/group/gmane.mail.imap.cyrus/last=/force_load=t (a thread
in info-cyrus with subject: "Cyrus HA & LB cluster summary")
Good luck (and please report back whatever you find!)
