Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

    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!)
