環境

  • ONTAP 9.8 以降
  • 温度に敏感な Storage Efficiency ( TSSE )

問題

  • 0B ONTAP 9.8では、インラインの自動適応圧縮が有効になっているすべてのボリュームで圧縮が表示されます。
::*> aggr show-efficiency -aggregate !*root,!*snaplock -fields volume-compression-saved
aggregate              volume-compression-saved
---------------------- ------------------------
aggr1              0B
aggr2                  0B

 
  • volume は重複排除による削減を示しますが、圧縮で削減されたスペースはありません。
::*> volume show -volume vol* -fields dedupe-space-saved,dedupe-space-saved-percent,compression-space-saved,compression-space-saved-percent vserver volume dedupe-space-saved dedupe-space-saved-percent compression-space-saved compression-space-saved-percent -------- -------------------- ------------------ -------------------------- ----------------------- ------------------------------- svm1 vol3 111.6GB 7% 0B 0% svm1 vol4 184.2GB 10% 0B 0%
  • 圧縮を手動で実行しようとすると次のエラーが発生して失敗し 
::*> volume efficiency start -vserver svm1 -volume vol1 -dedupe true -compression true -compaction true -scan-old-data true Warning: This operation scans all of the data in volume "vol1" of Vserver "svm1". It might take a significant time, and degrade performance during that time. Do you want to continue? {y|n}: y Error: command failed: Failed to start efficiency on volume "vol1" of Vserver "svm1": "-compression" option is not supported on auto-adaptive compression enabled volumes.
