NFS Volume
Create a volume as NFS share:
Check what file systems are shared via NFS:
Per default the volume is shared to all networks, to specify share options:
root # exportfs
To stop sharing the volume:
root # exportfs
root # zfs snapshot zfs_test/volume1@22082011
root # zfs list -t snapshot -o name,creation
root # zfs rollback zfs_test/volume1@21082011
root # zfs clone zfs_test/volume1@21082011 zfs_test/volume1_restore

总结：
1. zpool set bootfs=设置根系统的分支 pool_name --->> 如 zpool set bootfs=rpool/ROOT/archlinux rpool
2. grub-install --root-directory=/boot /dev/sdX --recheck 单独分区的时候
3. 在GPT分区模式下，设置一个EF02 (bios_分区类型)，然后不能将当前分区当做/boot，需要另建一个分区挂为/boot
4. zfs=池名称 zfs_force=1 表示相当于import 时加-f
