I have a fully running GPT ZFS RaidZ setup using what was at the time 8-HEAD
I cant remember the exact steps I took, but one thing I have different
is I have a root filesystem within my zpool
[paul@demophon /usr/home/paul]$ gpart show
=> 34 976773101 ada1 GPT (466G)
34 256 1 freebsd-boot (128K)
290 8388608 2 freebsd-swap (4.0G)
8388898 147912557 3 freebsd-zfs (71G)
156301455 820471680 - free - (391G)
=> 34 488394988 ada2 GPT (233G)
34 256 1 freebsd-boot (128K)
290 8388608 2 freebsd-swap (4.0G)
8388898 147912557 3 freebsd-zfs (71G)
156301455 332093567 - free - (158G)
=> 34 156301421 ada3 GPT (75G)
34 256 1 freebsd-boot (128K)
290 8388608 2 freebsd-swap (4.0G)
8388898 147912557 3 freebsd-zfs (71G)
[paul@demophon /usr/home/paul]$ zpool status
pool: zboot
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
zboot ONLINE 0 0 0
ada1p3 ONLINE 0 0 0
ada2p3 ONLINE 0 0 0
ada3p3 ONLINE 0 0 0
errors: No known data errors
[paul@demophon /usr/home/paul]$ zfs list
NAME USED AVAIL REFER MOUNTPOINT
zboot 33.5G 175G 18K none
zboot/root 12.4G 175G 12.2G none
zboot/tmp 82.9M 175G 82.6M none
zboot/usr 20.8G 175G 16.5G none
zboot/var 216M 175G 123M none
Im also using fstabs to mount my ZFS filesystems
[paul@demophon /usr/home/paul]$ more /etc/fstab
# Device Mountpoint FStype Options Dump
Pass#
zboot/root / zfs rw 0 0
zboot/usr /usr zfs rw 0 0
zboot/var /var zfs rw 0 0
zboot/tmp /tmp zfs rw,noatime 0 0
proc /proc procfs rw 0 0
I remember speak to someone a while back, and I *think* we came to the
conclusion that using the zpool as your root will not work correctly and
you should really create a root filesystem inside the zpool
Lets me know how this works out for you
