问题描述

中有一个很大的值Delayed Frees,即使设置了,在运行volume show-footprint命令时也可能不会更改。 -tiering-policy all.

如下Delayed Frees所示,的价值很大,而性能层上的剩余数据也是。

 Cluster::> volume show-footprint
(output ommitted)
    Vserver : SVM1
      Volume  : vol1

      Feature                                          Used    Used%
      --------------------------------           ----------    -----
      Volume Data Footprint                         15.41GB       0%
             Footprint in Performance Tier
                                                     4.65GB      25%
             Footprint in <Cloud Tier name>
                                                    14.14GB      75%
      Volume Guarantee                                   0B       0%
      Flexible Volume Metadata                      858.1MB       0%
      Cross Volume Deduplication                        4KB       0%
      Delayed Frees                                  3.38GB       0%
      Total Footprint                               19.62GB       0%

此外,还可能会观察到此现象的聚合已用总大小超过卷的总大小。
