Hello Anyons has tested this configuration with success ? I'll test it in few days and I am wondering if I am alone :-) Thanks

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).

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Thanks for the feedback ! I'll plan to run it at 7.2 and of course certainly not on a production server without numerous tests !

You need less tuning because off the greater memory maps available.(see the last paragraph of that page) regards, -- _______________________ *Johan Hendriks* *Schavemaker Transport* Tel: +31 (0)251 229098 Fax: +31 (0)251 212016 email: j.hendriks at schavemaker.com <mailto:j.hendriks at schavemaker.com> web: http://www.schavemaker.com _______________________
