My home server that is hosting this website is actually running a raidz on 4 1TB drives. The instructions below setup a gmirror for swap in addition to the zfs mirror, when I did the raidz setup I used two separate gmirror swap partitions so that I have swap spread out over all 4 disks and it will still survive a disk failure. Granted I don't think my server has actually ever needed to use the swap space so I can't be sure it wont grind to a crawl if it hits it. Fair warning I haven't actually read through these in a while, I wrote them back in 9.x days, I did modify them when it was no longer necessary to specify the boot data set in the loader.conf. I basically just install from memory, when needed. http://www.dweimer.net/?Content=03~help_files&Page=01~installing_FreeBSD_on_ZFS -- Thanks, Dean E. Weimer http://www.dweimer.net/
