适用场景

  • logical unit number(逻辑单元号)(LUN)
  • ONTAP 9

问题解答

Used Size 通常略大于LUN Size ,因为:

  • LUN Size 仅报告存放实际用户数据的 L0 块的总大小。 
  • Used Size 报告存放元数据 / 非用户数据的 L0 块和间接块的总大小。

示例

cluster::> lun show -instance

                  Vserver Name: svm1
                      LUN Path: /vol/vol1/lun1
                   Volume Name: vol1
                    Qtree Name: ""
                      LUN Name: lun1
                     LUN Size: 350GB
                       OS Type: linux
             Space Reservation: enabled
                 Serial Number: 801mG?QMdRIe
           Serial Number (Hex): 3830316d473f514d64524965
                       Comment:
    Space Reservations Honored: false
              Space Allocation: disabled
                         State: online
                      LUN UUID: 39597210-bb89-44bf-ac06-c926e55c4cd0
                        Mapped: unmapped
                    Used Size: 351.4GB
