問題

  • 自動削除が原因でボリュームでSnapshotが削除されています:

<Date> [<Node_Name>: snap_helper: wafl.volume.snap.autoDelete:info]: Deleting Snapshot copy '<Snapshot_Name>' in volume '<Volume_Name>' to recover storage

  • ボリュームSnapshotの自動削除 は次のように設定されています:

::> volume snapshot autodelete show
state=on, commitment=try,
trigger=volume,
target_free_space=20%,
delete_order=oldest_first,
defer_delete=user_created,
prefix=(not specified),
destroy_list=none

  • ボリュームのスペース使用量が「ターゲットの空きスペース」を超過しました: 

    <Date> [<Node_Name>: wafl_spcd_main: monitor.volume.nearlyFull:error]: Volume <Volume_Name>@vserver:<vserver UUID> is nearly full (using or reserving X%% of space and y%% of inodes).
