環境

  • ONTAP 9
  • 保存データの暗号化
  • オンボードキー管理ツール

問題

  • ノードの再起動中(メンテナンス、ONTAPアップグレードなどの理由による)、ギブバック障害が定期的に報告されます:

[node2: cf_giveback: gb.sfo.veto.kmgr.keysmissing:error]: Giveback of aggregate aggr1 failed due to the unavailability of the volume encryption keys for the encrypted volumes of the aggregate on partner node node1.

  • ギブバックは、拒否権を上書きすることで手動で実行され、その後暗号化されたボリュームはオフラインになります:

[node1: vv_apply_special18: wafl.mount.transient.error:error]: WAFL: Unable to mount volume vol1, UUID 2075XXXX-XXXX-XXXX-XXXX-XXXXXXXXea91 due to Encryption key error.. Volume is taken offline due to transient errors.

  • これがアップグレード中の場合、ANDU は一時停止できます:
