drbd in combination with heartbeat and a journalling filesystem can
do exactly this. You can have Cyrus IMAP running on both servers

Dear Kevin,
Yes, we ran UW impa for some time with drbd doing replication and it was
very successful. Of course UW imap doesn't have any databases so I don't
know whether that would cause a problem with drbd. I guess the worst case
would be a reconstruct perhaps but even that would be much better

Although I think Gerard likes to see both servers active at the same

do, I assume it must be possible with just 2
Yeah, master slave sort of thing would work nice. If the server losses
an email or two that would be no problem. Plus I can always set up an MX
record for both servers so it would be delivered no matter what. This
way if one server goes down I have the other as a backup and if server

Dear Paul and others,
I haven't tried it yet but it may be that DRBD (http://www.drbd.org)
might be able to do what you want. We used it with a UW Imap server and I
don't see why it shouldn't work with Cyrus. It is probably possible to
split the users between two cyrus servers and have each
