适用场景

  • ONTAP 9
  • 集群模式Data ONTAP 8.
  • Snapshot

问题描述

System Manager将显示大小为0 KB的快照。

  • 从命令行查看快照时、也会出现相同的行为:

::> volume snapshot show -vserver svm01 -volume volume1
               
 Vserver  Volume   Snapshot                  Size Total% Used%
-------- -------- ------------------------------------- -------- ------ -----
svm01
     volume1
          daily.2017-01-01_0010           5.55MB    0%   0%
          weekly.2017-01-01_0015          3.05GB    0%   0%
          daily.2017-01-04_0010             0B    0%   0%
          daily.2017-01-05_0010             0B    0%   0%
          daily.2017-01-06_0010             0B    0%   0%

  • Snapshot大小会在创建后更改。

可以 运行以下命令来检查Snapshot空间使用量:

        volume snapshot show 命令可显示有关Snapshot副本的信息

::> volume snapshot show -volume vol_name

volume Snapshot compute -relaimable 命令可计算删除一个或多个指定Snapshot副本后可回收的卷空间。

注意: 此任务可能运行时间较长。
::> volume snapshot compute-reclaimable -vserver SVM_name -volume vol_name -snapshots snapshot_name 

For volume snapshot compute-reclaimable command options, refer to the man page
