[Dovecot] Dovecot + FreeBSD-7.2 + ZFS ?

[Dillon Kass]

We use this at work on a fairly busy server with about 1300 email 
accounts. I also use this configuration for my personal server.

It works great, I don't know if you've been using ZFS on 7.0 or 7.1 but 
with 7.2 a lot of nasty things are fixed and it is very stable. On 
earlier versions of FreeBSD with ZFS you needed mmap_disable = yes in 
your dovecot.conf or the index files would get corrupted but that has 
long since been fixed.

I don't know how comfortable you are with FreeBSD but if the answer is 
very you should seriously look in to either checking out RELENG_7 
(optimal) or grabbing this source 
http://svn.freebsd.org/base/user/kmacy/releng_7_2_zfs/ (use 
subversion-freebsd port, keep in mind you wont be able to update your 
source with csup to patch 7.2 because you will end up with an older 
zpool version, you'll need to apply future patches to 7.2 manually).

The ladder is 7.2-RELEASE with the special ZFS v13 code that was 
recently committed. I can tell you with confidence this runs much better 
than the ZFS v6 stuff in the stock 7.2-RELEASE. We have moved almost 
everything over to it and it is absolutely beautiful. You also get all 
the newer zfs dataset features in the v13 stuff (like being able to 
assign l2 arc cache devices, say a really fast ssd to cache maildirs).

Cheers,
Dillon
