I have a set of instructions I wrote for a manual install on ZFS root
with a mirror, these can easily be modified to use a raidz partition
instead. 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.
