接下來的目標是把其他3顆合併成一顆的容量來使用。
查詢目前ZFS的狀態，已建立rpool的root pool，使用了一顆硬碟（c4t5000C500091FB283d0s0）
bash-3.2# zpool status
pool: rpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c4t5000C500091FB283d0s0 ONLINE 0 0 0
errors: No known data errors
接著查詢系統內磁碟的訊息，由下可知共有四個磁碟，還有三個尚未使用
bash-3.2# format

建立一個空的文件夾，作為mount point
bash-3.2# mkdir /test
新建一個pool並加入三個硬碟，加入參數-f，強制硬碟加入
bash-3.2# zpool create -f dpool c4t5000C5000EA30353d0 c4t5000C500091EA2C7d0 c4t5000C5000EA49A43d0
'dpool' successfully created, but with no redundancy; failure of one
device will cause loss of the pool
bash-3.2#
如果要加入已是其他pool的硬碟時，就算有強制的參數-f ，仍會出現錯誤。
bash-3.2# zpool add -f dpool c4t5000C500091FB283d0
invalid vdev specification
the following errors must be manually repaired:
/dev/dsk/c4t5000C500091FB283d0s0 is part of active ZFS pool rpool. Please see zpool(1M).
/dev/dsk/c4t5000C500091FB283d0s2 is part of active ZFS pool rpool. Please see zpool(1M).
查詢新建之後的狀態
bash-3.2# zpool status
pool: dpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
dpool ONLINE 0 0 0
c4t5000C5000EA30353d0 ONLINE 0 0 0
c4t5000C500091EA2C7d0 ONLINE 0 0 0
c4t5000C5000EA49A43d0 ONLINE 0 0 0
errors: No known data errors
pool: rpool

config:

rpool ONLINE 0 0 0
c4t5000C500091FB283d0s0 ONLINE 0 0 0

將dpool指定一個mount point
bash-3.2# zfs set mountpoint="/test" dpool
完成後，就可以像一般操作一樣操作資料夾，總容量為402G。
bash-3.2# df -h
Filesystem size used avail capacity Mounted on
（略…）
dpool 402G 31K 402G 1% /test
