Why? I've had better luck with ZFS than I've had with VINUM and GEOM in the past, and I've put my ZFS "array" through alot of stress. If his data (photo / video storage) is that important, then perhaps he wants to do soemthing else ... but for a cheap way to get tons of storage, ZFS can't be beat. ZFS has got it's caveats and gotchas - you *must* tune your FreeBSD installation to get stability. See here: http://wiki.freebsd.org/ZFSTuningGuide I'm running a fileserver-in-a-closet (patent pending) on FreeBSD 7.0- amd64, with 10x250GB drives in a single RAIDZ2 for my home storage needs. I'm using old Maxtor SATA150 drives, which are "desktop" class. Several of them have had to remap sectors while being a part of the array, and I've never had ZFS complain, nor had the drive be "dropped" by the OS. I'd suggest that the OP and yourself do some in-depth reading about ZFS and how it works. The best documentation I've found as yet is here: http://opensolaris.org/os/community/zfs/docs/ondiskformat0822.pdf Charles Richards richardsc@gmail.com charlesrichards.net On Jan 2, 2009, at 8:07 AM, Wojciech Puchar wrote: >> Hi freebsd-questions, >> >> For personal use (photo/video storage), I'm looking into creating a >> huge >> single ZFS (raidz) volume that will replace my current collection of >> drives used as storage.
