リストアしたらSSDが圧迫されてしまう
こんにちは、のんピ(@non____97)です。
皆さんはAmazon FSx for ONTAP(以降FSxN)のボリュームのバックアップ運用難しすぎないか?と思ったことはありますか? 私はあります。
以下記事で紹介しているように、FSxNファイルシステムに書き込む場合は一度SSDに書き込まれます。これはリストアする際も同じで、ボリュームのTiering PolicyがAllであっても、必ずSSDに書き込まれます。
この影響により、SSDの空き容量に対してバックアップ対象のデータが非常に大きい場合は、そのままFSxNファイルシステムにリストアするととSSDの枯渇は避けられません。回避方法としてはボリュームを細かくして分割して、SSDの大きさを超えないように設計したり、一度別のFSxNファイルシステムにリストアしてから、そこからSnapMMirrorで転送するというアプローチが求められました。ここの言及は以下記事でも言及されています。
今回、アップデートにより、バックアップからリストアする際にバックグラウンドでキャパシティプールストレージに階層化されるようになりました。
When restoring a backup, all the data is first written to the SSD storage tier before the service begins tiering data to the capacity pool storage according to the tiering policy you set for the restored volume. When restoring a backup to a volume with a tiering policy of All, a periodic background process tiers the data to the capacity pool. When restoring a backup to a volume with a tiering policy of Snapshot Only or Auto, data is tiered to the capacity pool if the SSD utilization for the file system is greater than 50%, and the cooling rate is determined by the tiering policy’s cooling period.
(以下機械翻訳)
バックアップをリストアする場合、サービスがリストアされたボリュームに設定した階層化ポリシーに従って容量プール ストレージへのデータの階層化を開始する前に、まずすべてのデータがSSDストレージ階層に書き込まれます。ティアリング ポリシーが［すべて］のボリュームにバックアップをリストアする場合、定期的なバックグラウンド プロセスによってデータが容量プールにティアリングされます。階層化ポリシーが［スナップショットのみ］または［自動］のボリュームにバックアップをリストアする場合、ファイルシステムのSSD使用率が50%を超えるとデータは容量プールに階層化され、冷却率は階層化ポリシーの冷却期間によって決定されます。
これはバックアップの使い勝手が非常によくなりそうです。
実際に試してみました。
いきなりまとめ
- バックアップからリストアする際にバックグラウンドでキャパシティプールストレージに階層化するうになった
- ただし、Tiering Policy Allであっても、SSDに一切書き込まれないという代物ではない
- バックアップからリストアしたボリュームのTiering PolicyをAllにする場合、圧縮を維持できない
やってみた (Tiering Policy All)

その前にボリューム、aggregate、Storage Efficiencyの状態を確認しておきましょう。Tiering PolicyはNoneでStorge Efficiencyは有効にしています。

Effective Total Footprint 6.91GB 1%SSDとキャパシティプールストレージの使用量のCloudWatchメトリクスは以下のとおりです。9:40ごろにリストアを開始し、緑色の線がSSD使用量、赤色の線がキャパシティプールストレージ使用量です。
以前は以下のようにリストアが完了したタイミングでSSDからキャパシティプールストレージに階層化されていました。アップデートにより、この階層化がバックグラウンドでかかるようになったことが分かります。一方で、直接キャパシティプールストレージに書き込むような代物ではないので注意が必要です。
抜粋 : リストアしたAmazon FSx for ONTAPのボリュームのデータは必ずプライマリストレージに書き込まれる件 | DevelopersIO
SnapMirrorの転送先ボリュームのTiering PolicyがAllの場合は圧縮されるのか
先ほどの検証で一点気になるのはリストアされたボリュームはキャパシティプールストレージ上のデータが圧縮されていないという点です。aggregateやボリュームの情報を確認すると、FSxFabricpoolObjectStoreが41.42GBとリストア前後と比較して非常に大きいです。(リストア前は1.34GB)

2 entries were displayed.71.56GBと圧縮はまたしても効いていなさそうです。一方でバックアップからのリストアとは異なり重複排除は維持してくれるので、物理消費量はその分抑えられています。
SSDとキャパシティプールストレージの使用量のCloudWatchメトリクスは以下のとおりです。11:20ごろにリストアを開始し、緑色の線がSSD使用量、赤色の線がキャパシティプールストレージ使用量です。
SSDの消費量はバックアップからリストアするよりも抑えられていますね。また、今回の検証ではリストア時間とSnapMirrorの転送時間は大きく変わりありませんでした。
Amazon FSx for NetApp ONTAPのバックアップの使い勝手が改善されました
ボリュームのバックアップからTiering Policy Allでリストアする際にバックグラウンドでキャパシティプールストレージに階層化されるようになったアップデートを紹介しました。
Amazon FSx for NetApp ONTAPのバックアップの使い勝手が改善されましたね。ただし、SSDを圧迫するリスクは相変わらず抱えたままです。SSDの空き容量を極力少なくしたいのであれば、SnapMirrorを使ったバックアップをお勧めします。
この記事が誰かの助けになれば幸いです。
