Good luck!
FYI, my mail spools are on ZFS filesystems under Solaris on UltraSPARC. It is lightning fast with 100+ dovecot imap processes pounding away. I've not yet enabled compression and done the copy/recopy dance, though.

I was not aware of that... I went with FUSE to test the deduplication feature of ZFS. I'll check out this link you've provided, many thanks Dave. :)

I'm testing out ZFS-fuse on my new install (talked about it on the other thread), no issues so far. The builtin deduplication and compression sure do help a lot, roughly 30% less storage space required so far.
They don't advertise it as exactly "production" quality, but I'm willing to try it out, we're doing regular backups. The mail system hasn't gone live yet though, so I'm a bit uneasy on the performance side of things under heavy load.
You are aware that there's a real in-kernel ZFS implementation under Linux now, right? See http://zfsonlinux.org/. I've done some very basic testing with it, and so far, it works. Going through FUSE is slower than pissing tar; this implementation won't have that problem.
FUSE is useful for many things. Performance-sensitive filesystems on production servers is oh-so-NOT one of them. ;)
