Hi, i prefere use zfsboot boot sector, an example is better than a long talk:
$ zpool create tank mirror ad4 ad6 $ zpool export tank $ dd if=/boot/zfsboot of=/dev/ad4 bs=512 count=1 $ dd if=/boot/zfsboot of=/dev/ad6 bs=512 count=1 $ dd if=/boot/zfsboot of=/dev/ad4 bs=512 skeep=1 seek=1024 $ dd if=/boot/zfsboot of=/dev/ad6 bs=512 skeep=1 seek=1024 $ zpool import tank $ zpool set bootfs=tank tank $ zfs set mountpoint=legacy tank add vfs.root.mountfrom="zfs:tank" to your loader.conf now you can boot on ad4 or ad6 Source: http://www.waishi.jp/~yosimoto/diary/?date=20080909 2009/5/25 Philipp Wuensche <cryx-free...@h3q.com>: > Lorenzo Perone wrote: >> >> Hello to all, >> >> Having licked blood now, and read the news from Kip Macy about >> >>> - zfs boot for all types now works >> >> >> I was wondering if anyone has some updated tutorial on how to achieve a >> zfs-only bootable FreeBSD with a mirrored zpool. > > My own howto and script to do the stuff automated: > http://outpost.h3q.com/patches/manageBE/create-FreeBSD-ZFS-bootfs.txt > > But beware, it is meant to use with > http://anonsvn.h3q.com/projects/freebsd-patches/wiki/manageBE > afterwards.
