Hi all,

I'm testing Dovecot version 1.2.17 on FreeBSD 8.2-RELEASE using ZFS as filesystem. Searching on google I've ridden about some problem concerning indexes and mmap.

I wold like to know if this problem persists on the latest releases.

I use Dovecot 2.0.12 on FreeBSD 8.2-RELEASE and didn't see any index corruption in log so far. Admittedly the setup is relatively new, and have been running for only 63 days now, but my understanding is that I shouldn't be that lucky. Also, FreeNAS uses both mmap and sendfile and we didn't see data corruption either nor see any reports about that.

Note that my instance is running a heavily modified version (with some driver updates, ZFSv28, etc) though, the latest 8-STABLE have most of the ZFS changes I had in my own tree but I don't think these changes are related to data corruption.

If, however, you could reproduce a data corruption on your installation on a recent unmodified FreeBSD 8.2-RELEASE system, please do let me know or post your complain on freebsd-stable@freebsd.org, as that would be a pretty serious problem and we will get it fixed as soon as possible.

Cheers,
