Does anybody know about GlusterFS & Dovecot?

Time marches on, and I need to continue the service migration. I'd still like to use Dovecot (we're migrating away from Cyrus). I'm assuming the only other alternative without existing shared storage is to use 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.
