1) How large is your Cyrus installation (# of accounts, # of simultaneous connections and IMAP spool size) 2) What DRBD protocol are you using A,B or C and over what file system (EXT2, LVM,& EXT3 ???) 3) Are you using block replicated disks for both your IMAP spool & your IMAP directory (Mailboxes DB etc)?
