解決策

  • 場合によっては、ボリューム効率を有効にすることでこの問題を解決できます:

::> volume efficiency on -vserver <vserver_name> -volume <volume_name>

    これが失敗した場合は、

    Please contact NetApp Technical Support or log into the NetApp Support Site to create a case. Reference this article for assistance with the solution. 

    • The solution requires Diagnostic-level recovery. 
    • The use of Diagnostic commands and recovery steps is potentially disruptive and should only be used with guidance from NetApp Support.

バグ 1328903の内部回避策に従ってください:

  1. ボリューム内の重複排除メタファイルを特定します:

cluster1::> node run -node cluster1-01
Type 'exit' or 'Ctrl-D' to return to the CLI
cluster1-01> priv set diag
Warning: These diagnostic commands are for use by NetApp
personnel only.
cluster1-01*> sis ls /vol/vol
Error listing sis metafiles in aggregate for /vol/vol: Metafile does not exist
SIS metadata in flexible volume vol:
Filename Size Blocks Used
-------------------------------------------------------- ----------- -----------
dense_state_bin 0KB 1
Total files: 1. Total blocks used: 1
cluster1-01*>

  1. 上記でファイルが報告されない場合は、以下を実行する必要がある可能性があります:

cluster1::> node run -node cluster1-01
cluster1-01> priv set diag
cluster1-01*> setflag wafl_metadata_visible 1
cluster1-01*> ls /vol/vol/metadir/dense

  1. メタファイルが見つかり識別されたら、WAFLメタデータの可視性を無効にします:

cluster1-01*> setflag wafl_metadata_visible 0

  1. dense_state_binファイルをsis resetで削除します:

cluster1::> node run -node cluster1-01
cluster1-01> priv set diag
cluster1-01*>
cluster1-01*> sis reset /vol/data_vol dense_state_bin 1

  1. 重複排除メタデータを削除した状態で、ボリューム移動処理を再試行します
