問題

  • snapshot-only階層化ポリシーを持つボリュームは、27.5TBを超えるデータがFabricPoolバケットに階層化されています。
  • スナップショットの使用済みスペースを見ると、ボリュームのスナップショットは300GB未満です:

cluster1::> df -h vol1

Filesystem           total    used    avail  capacity  Mounted on          Vserver
/vol/vol1/           40.83TB   39.86TB  991.42GB   98%  /vol1            vol1
/vol/vol1/.snapshot        0B     267.65GB   0B    0%  /vol1/.snapshot        vol1
