#ee /etc/rc.conf
加入zfs_enable="YES"
啟用
#service zfs start

建儲存池的磁碟
zpool create raiddisk /dev/da0
強制建立加-f
zpool create -f raiddisk /dev/da0
監控其狀態 (state) 的方式
zpool status -x
刪儲存池
zpool destroy raiddisk
儲存池上建立一個有開啟壓縮功能的資料集：
zfs create raiddisk/compressed
zfs set compression=gzip raiddisk/compressed
壓縮功能關閉指令
zfs set compression=off raiddidk/compressed

zfs create raiddisk/share
檔案額外備份的功能
zfs set copies=2 raiddisk/share

建第2顆備份碟
zfs create backdisk /dev/ada1

#zfs create raiddisk/home

# cp -rp /home/* /raiddisk/home
# rm -rf /home /usr/home
# ln -s /raiddisk/home /home
# ln -s /raiddisk/home /usr/home

#zfs create raiddisk/mysql
#chown mysql:mysql /raiddisk/mysql

# cp -rp /var/db/mysql/* /raiddisk/mysql
# rm -rf /var/db/mysql
# ln -s /raiddisk/mysql /var/db/mysql

#zfs create raiddisk/mail
#chgrp mail /raiddisk/mail
#chown 775 /raiddisk/mail
# cp -rp /var/mail/* /raiddisk/mail
# rm -rf /var/mail
# ln -s /raiddisk/mail /var/mail
