The only problem with rolling replication is that if you fail over to
the replica and mail gets delivered to it. When you bring the master
back up unless you are carefull (i.e. switch which is master and which

I learned that Cyrus IMAPd (for whatever reason) is quite picky on
filesystems. From the FAQ:

Search for rolling replication. Thou
You'll need to upgrade primary and replica backends together for a
2.3.7 to 2.3.8 upgrade. Other than that, you can upgrade just one
backend pair in a 2.3.7 cluster, no problem. Once you have
confidence in the correctness of 2.3.8, upgrade the rest of the
backends. It's also pretty commo

For those with medium to large scale murders or other glued together

Do you take downtime for the entire cluster and upgrade, or do you
roll through upgrades of the parts?
The latter would be prudent, except that I discov

But this will "just" provide the HA filesystem, won't it?
Isn't there a technology available in Cyrus IMAPd which will replicate
changes to a mailbox to two different servers?

Hi Phillipe!
Your question is very valid in the first place; a lot of people are looking for
that scenario. (Including one of the sites which I work on right now.)
I think you will have to become clear of some things:

i´m looking for a strategy to synchronize the primary mailserver to a

a mail is stored in inbox on primary server.

Hi all
I'm experimenting with cyrus 2.2.12 configured to support UNIX namespaces and
virtual domains.
Using cyradm as administrative user I issued:
localhost.localdomain> cm group/[EMAIL PROTECTED]
that resulted OK, and mailbox is listed with lm.
localhost.localdomain> lam group/[EMAIL PROTECTE
Hi All
we are planning a migration from 2.15 to 2.3.3 to a new box. Synced over
/var/imap and and ran the conversion for .seen files as suggested in
install-upgrade using cvt_cyrusdb. But all the mail in the inbox on the
new servers are reset to unread. Is there anything else I need to do?
