Does anybody know about GlusterFS & Dovecot?
Time marches on, and I need to continue the service migration. I'd

like to use Dovecot (we're migrating away from Cyrus). I'm

DRBD
and a cluster file system to provide the replication, and to
ensure
Director is enabled. Are there any things to watch for
surrounding
this?
I still want my dream of the perfect mail storage engine in
dovecot to one day to be true.
This magical mailbox format & storage engine would allow
storing emails in different geographical locations. There
would be an attempt to ensure that mail is always closest
to the user (ie, the mail server that the user connects
to retrieve email from).
Then you could define how many copies of each user's mail
would be stored on a per-user basis, but those copies could
be stored on any storage server, but not more then x times
per network location.
Unfortunately, this mystical engine does not sound like
it is going to be built in the next handful of years at
least.
A man can dream.

Tim, I too have had this dream but it feels very much like people just
don't care about Geo-distributed messaging at scale. Since Dovecot now
supports storing messages in s3 compatible storage (using obox) I was
thinking about extending an object storage app I developed using node.js
on top of Cassandra to implement the s3 API and see if that could breath
some life into this concept. When time permits I suppose.
