問題

  • FlexVol または FlexGroup 構成ボリューム上のスナップショットには、論理 ID 0 が表示されます。
  • このシナリオでは、論理ID 0のスナップショットはSnapMirror関係のソースボリューム上に存在します。
  • 論理ID 0のスナップショットがWAFLガベージコレクションの前に転送されると、無効なスナップショットが原因でSnapMirrorのスケジュールされた更新が失敗する可能性があります。  エラーの例:

Failed to complete transfer of snapshot [snapshot ID] to destination [sm_dest_SVM:dest_vol] because the destination is prepared for the transfer of a different snapshot. Run "snapmirror resync" or "snapmirror abort -hard" to cleanup the checkpoint and issue the operation again.
Failed to start transfer for Snapshot copy [snapshot name].(Failed to start transfer.(Snapshot access error(Replication engine error)))

  • スケジュールされた更新が失敗した場合は、手動による介入が必要です (回避策のセクションを参照)。
