::> lun show /vol/NetApp_VOL/lun_NetApp_VOL -fields space-reserve
vserver path               space-reserve
------- ------------------------------- -------------
svm1   /vol/NetApp_VOL/lun_NetApp_VOL  enabled

• 检查卷中的可用空间：

::> df -h NetApp_VOL
Filesystem              kbytes       used          avail capacity  Mounted on
/vol/NetApp_VOL/      8332236556   8332236556    0     100%      /vol/NetApp_VOL/

• 检查卷 / 存储效率是否已启用且正在运行：

::> vol efficiency show NetApp_VOL
