Amazon FSx for NetApp ONTAP で SnapMirrorのカスケードをしてみた
移行や二次バックアップに
2023.12.27本番ワークロードのONTAPからSnapMirrorで移行するのは避けたい
こんにちは、のんピ(@non____97)です。
皆さんはオンプレミスONTAPからAmazon FSx for NetApp(以降FSxN)に以降する際に、本番ワークロードのONTAPを触るのは避けたいなと思ったことはありますか? 私はあります。
本番ワークロードに対して何か設定変更を加えたことによって、負荷がかかってしまい業務に影響があるのは避けたいところです。
おおよそ、重要なワークロードについてはSnapMirror/SnapVaultでSnapshotコピーを別のONTAPに転送していると考えられます。
そのような場面では転送先のONTAPからFSxNに対して、さらにSnapMirrorでSnapshotコピーを転送したいものです。果たしてそんなことはできるのでしょうか。
はい、SnapMirrorのカスケード構成を組むことで対応可能です。
抜粋 : How to configure SnapMirror cascade relationship - NetApp Knowledge Base
SnapMirrorのカスケードを行うことで、ソースボリュームのパフォーマンスを低下させずに、別のストレージにSnapshotコピーを転送することができます。
実際に試してみました。
いきなりまとめ
- カスケードSnapMirrorでは
snapmirror protectを使用することができない - カスケードSnapMirrorでも重複排除やaggregateレイヤーのデータ削減効果を維持できる
- 2つ目のボリュームで実行したStorage Efficiencyによる重複排除効果を3つ目以降のボリュームに維持するためには、
転送元ボリューム -> 2つ目のボリューム -> 3つ目のボリュームで2回SnapMirrorによる転送を行う必要がある - 2つ目のボリュームで実行したInactive data compressionなどaggregateレイヤーのデータ削減効果を3つ目以降のボリュームに維持するためには、
2つ目のボリューム -> 3つ目のボリュームでSnapMirrorを転送するだけでよい- ただし、転送元ボリュームのTiering PolicyがAllの場合は、aggregateレイヤーのデータ削減効果を維持できない
- カスケードSnapMirrorの中間のボリュームが使用できなくなった場合、直接転送元ボリュームから最終的な転送先ボリューム間で同期を行うことができる
- 中間ボリュームと最終的な転送先ボリューム間のSnapMirror relastionshipを削除した上で、転送元ボリュームと最終的な転送先ボリューム間でSnapMirror relasionshipの作成をし、
snapmirror resyncによる再同期が必要 - 再同期する際、共通のSnapshot以降に保持しているデータは削除される
- 中間ボリュームと最終的な転送先ボリューム間のSnapMirror relastionshipを削除した上で、転送元ボリュームと最終的な転送先ボリューム間でSnapMirror relasionshipの作成をし、
検証環境
検証環境の構成は以下のとおりです。
今回は同一FSxNファイルシステム内で完結していますが、それぞれ別のFSxNファイルシステム間でも問題なく動作します。
その際のクラスターピアリングやSVMピアリングはソースクラスターと最終的な転送先のクラスター間で行う必要はありません。直接SnapMirrorで転送するクラスター間でのみクラスターピアリングやSVMピアリングを行えば良いです。
SnapMirrorでは、SnapMirrorデスティネーションから別のシステムにデータをレプリケートできます。したがって、あるSnapMirror関係のデスティネーションであるシステムを、別のSnapMirror関係のソースとして使用できます。これは、1つのサイトから複数のサイトにデータを分散する場合に便利です。これをカスケードと呼びます。カスケードトポロジでは、プライマリクラスタとセカンダリクラスタの間、およびセカンダリクラスタとターシャリクラスタの間に、クラスタ間ネットワークを作成する必要があります。プライマリクラスタとターシャリクラスタの間にクラスタ間ネットワークは必要ありません。に、2個のホップから成るカスケード構成の例を示します。
SVMは以下の3つを用意しました。

テスト用ファイルを書き込むvol1はTiering Policy Noneで、Storage Efficiencyは無効化しています。これはファイルを作成するタイミングで重複排除や圧縮などがかかるのを防ぐためです。

テスト用ファイルの作成
テスト用のファイルを作成します
作成するファイルは以下の3つです。
1で埋めた1GiBのテキストファイル- ランダムブロックの1GiBのバイナリファイル
- 2のコピー
1つ目のファイルは重複排除や圧縮が効くのかどうかを確認するためで、2つ目と3つ目のファイルは重複排除が効くのかを確認するためのファイルです。
作成時のログは以下のとおりです。
$ sudo mount -t nfs svm-0058ae83d258ab2e3.fs-0ab6f9b00824a187c.fsx.us-east-1.amazonaws.com:/vol1 /mnt/fsxn/vol1 $ df -hT -t nfs4 Filesystem Type Size Used Avail Use% Mounted on svm-0058ae83d258ab2e3.fs-0ab6f9b00824a187c.fsx.us-east-1.amazonaws.com:/vol1 nfs4 16G 320K 16G 1% /mnt/fsxn/vol1 $ head -c 1G /dev/zero | tr \\0 1 | sudo tee /mnt/fsxn/vol1/1_padding_file > /dev/null $ ls -lh /mnt/fsxn/vol1/ total 1.1G -rw-r--r--. 1 root root 1.0G Dec 22 01:46 1_padding_file $ sudo dd if=/dev/urandom of=/mnt/fsxn/vol1/urandom_block_file bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 6.25093 s, 172 MB/s $ sudo cp /mnt/fsxn/vol1/urandom_block_file /mnt/fsxn/vol1/urandom_block_file_copy $ ls -lh /mnt/fsxn/vol1/ total 3.1G -rw-r--r--. 1 root root 1.0G Dec 22 01:46 1_padding_file -rw-r--r--. 1 root root 1.0G Dec 22 01:47 urandom_block_file -rw-r--r--. 1 root root 1.0G Dec 22 01:47 urandom_block_file_copy $ df -hT -t nfs4 Filesystem Type Size Used Avail Use% Mounted on svm-0058ae83d258ab2e3.fs-0ab6f9b00824a187c.fsx.us-east-1.amazonaws.com:/vol1 nfs4 16G 3.1G 13G 20% /mnt/fsxn/vol1
Storage Efficiencyを無効化しているので、重複排除は行われず3.1GB消費されていることが分かります。
ファイル作成後、ONTAP CLIからボリュームやaggregateの情報を確認します。

重複排除は行われていないようです。ただし、Space Saved by Aggregate Data Reduction: 1017MBであることからaggregateレイヤーで何かしらのデータ削減が行われていそうです。Storage Efficiencyを無効にしているため、圧縮やコンパクションも効いていつもりですが何でしょうか。

svm2にvol1_dstというボリュームが作成されています。転送元ボリュームであるvol1はStorage Efficiencyが有効ですが、こちらのボリュームはStorage Efficiencyが無効になっています。
また、Space Saved by Aggregate Data Reductionは1.99GBと1GB弱増えていました。このことからSnapMirrorがaggregateレイヤーでのデータ削減効果を維持してくれていることが分かります。

vol1_dst で Inactive data compressionを実行
svm2のボリュームであるvol1_dstでInactive data compressionを実行します。
重複排除よりも先に圧縮したのは、圧縮効果をわかりやすくするためです。仮に重複排除後に圧縮をすると、1で埋め尽くしているテキストファイルは重複排除によりほとんどのデータが削減されてしまい、圧縮が行われたのか分かりづらくなってしまうのではないかと考えます。

注目すべきポイントはIncompressible Data Percentage: 66%になっているところです。これは全体の66%のデータを圧縮できなかったという意味です。3GiB書き込んだうちの2GiBがランダムなデータブロックのバイナリファイルです。そして、以下記事でも確認しているとおり/dev/urandomで生成したランダムなデータブロックのバイナリファイルはInactive data compressionではほとんど圧縮できません。
そのため、おそらく1で埋めたテキストファイルは圧縮済みで圧縮しなかったのではないかと推測します。

Space Saved by Aggregate Data Reductionの結果は変わっていませんが、volume show-footprintのAuto Adaptive Compressionが1.01GBとなっています。
このことから元々aggregateレイヤーで圧縮が行われていたと推測されます。
vol1_dst で Storage Efficiencyを実行
次にsvm2のボリュームであるvol1_dstでStorage Efficiencyを実行します。

重複排除量が1.89GBとなっていますね。
ただし、Total Physical Usedが4.25GBから4.41GBに僅かならが増えています。そのため、重複排除したデータブロックは物理的には解放されていないことが分かります。

重複排除が効いているとvol1_dstから転送しているにも関わらず、vol1_dst_dstでは重複排除が一切効いていないようです。
vol1_dst_dst上のSnapshotを確認すると、vol1、vol1_dst_dstと全く同じものでした。vol1_dstとvol1_dst_dstのSnapMirror relationshipのSnapMirror policyはMirrorAllSnapshotsです。こちらのSnapMirror policyにはsm_createdのルールが存在しています。

そのため、「SnapMirror時にSnapshotを作成してくれるのかな?」と思ったのですが、そういう訳ではないようです。
これはSnapMirrorの転送元ボリュームのボリュームタイプがRWではなく、DPであるためです。DPのボリュームでSnapshotを作成しようとすると、以下のようにエラーになります。
::*> snapshot create -vserver svm2 -volume vol1_dst -snapshot test.2023-12-22_0459 -snapmirror-label test Error: command failed: Snapshot copies can only be created on read/write (RW) volumes
Space Saved by Aggregate Data Reduction: 2.98GBとSnapMirror前後で1GB増加しています。そのため、SnapMirrorのカスケードにおいてもaggregateレイヤーのデータ削減効果は維持されると考えて良さそうです。
また、無効だったInactive data compressionは有効化されていますね。
カスケードSnapMirrorの再転送
テスト用ファイルの追加
カスケードSnapMirrorの再転送をしてみましょう。
下準備としてテスト用ファイルを追加します。
作成するファイルは以下の3つです。
aで埋めた1GiBのテキストファイル- ランダムブロックの1GiBのバイナリファイル
- 2のコピー
1つ目のファイルは重複排除や圧縮が効くのかどうかを確認するためで、2つ目と3つ目のファイルは重複排除が効くのかを確認するためのファイルです。
作成時のログは以下のとおりです。

vol1_dstの重複排除量が1.89GBから3.47GBと約1.6GB分増えています。
vol1での重複排除量が約800MBであるので、それを差し引いても800MBほど追加の重複排除が発生しています。これはurandom_block_file2とurandom_block_file2_copy間、もしくはa_padding_file内で重複排除が行われたものと考えられます。
追加の重複排除が行われたのはvol1_dstのtest.2023-12-22_0533のサイズが893.2MBであることからも推測できます。
また、Space Saved by Aggregate Data Reductionが3.96GB から4.92GBと1GBほど増加していました。

vol1_dst_dstの重複排除量が3.83GBとvol1_dstとおおよそ同じ値になりました。
つまりはカスケードSnapMirrorで2つ目のボリュームで実行したStorage Efficiencyの結果を転送先ボリュームでも維持できることが分かります。
また、Space Saved by Aggregate Data Reductionは4.96GBから5.89GBと1GB増加していました。
既にSnapMirrorで転送したファイルと重複している場合に重複排除が効くのか
svm のボリュームのTiering PolicyをAllに変更
あまりカスケードSnapMirrorと関係ありませんが、既にSnapMirrorで転送したファイルと重複している場合に重複排除が効くのかを確認してみます。
ボリューム内にあるファイルをコピーした際に重複排除が行われないようにvol1のTiering PolicyをAllに変更します。

Space Saved by Aggregate Data ReductionはTiering前後で変わっていませんね。そのため、Tieringをしてもaggregateで実行されたデータ削減の効果が維持されていることが分かります。
この処理は以下のアップデートによるものです。文章だけ見ると「キャパシティプールストレージ上で追加の圧縮をかけられるようになった」ように認識してしまいそうですが、「キャパシティプールストレージに階層化するタイミングで圧縮するようになった」というものです。

重複排除量が3.89GBから4.96GBと1GB増加していました。
このことから既にSnapMirrorで転送したファイルと重複している場合に重複排除が効くことが分かります。
Space Saved by Aggregate Data Reductionは変わりありませんでした。このことからキャパシティプールストレージ上のaggregateのデータ削減効果は、SnapMirrorで転送すると失われると考えられます。

重複排除量が5.08GBとなっています。問題なく重複排除量が維持されていますね。
加えてvol1_dst_dstのStorage Efficiencyのprogressが更新されていることからSnapMirrorで転送されたデータに対して重複排除が行われたことが分かります。
また、Space Saved by Aggregate Data Reductionは7.77GBから8.36GBと600MBほど増加しています。
svm と svm3 のボリューム間のSnapMirror
SVMピアリングの追加
次にsvm と svm3 のボリューム間のSnapMirrorを試します。
以下NetApp公式ドキュメントに記載の通り、カスケードSnapMirrorの中間のボリュームが使用できなくなった場合、直接転送元ボリュームから最終的な転送先ボリューム間で同期を行うことができるようです。
Bのボリュームが使用できなくなった場合は、CとAの間の関係を同期することでAの保護を継続できます。ベースライン転送を新たに実行する必要はありません。再同期処理が終わると、AはBを迂回してCと直接ミラー関係を持つことになります。ただし、再同期処理を実行するときは、再同期によってSnapshotコピーが削除され、カスケード内の関係の共通Snapshotコピーが失われる可能性があることに注意してください。その場合、関係には新しいベースラインが必要になります。
次の図に、ミラー-ミラー カスケード チェーンを示します。
実際に試しみましょう。
まずは、svmとsvm3間のSVMピアリングを追加します。

svm2 と svm3 のボリューム間のSnapMirror relasionshipの削除
svmとsvm3のボリューム間のSnapMirror relasionshipを作成するにあたって、svm2 と svm3 のボリューム間のSnapMirror relasionshipの削除を行います。
これはONTAPの仕様上、SnapMirror relationshpの転送先ボリュームを重複する(fan-in)ことはできないためです。SanpMirror relasionshipが存在する場合、状態がBroken-offであっても以下のようにエラーになります。
::*> snapmirror create -source-path svm:vol1 -destination-path svm3:vol1_dst_dst -policy MirrorAllSnapshots Error: command failed: Relationship with destination svm3:vol1_dst_dst already exists.

重複排除量やaggregateレイヤーでのデータ削減量に大きな変化はありませんでした。再同期するにあたってせっかくデータ削減したものが削除されてしまうのかと思っていたのですが、そんなことはないようです。

また、vol1_dst_dstのStorage EfficiencyがDisableになっていました。snapmirror breakを実行してもStorage EfficinecyはEnableのままである認識です。そのため、snapmirror resyncのタイミングでDisableになったと考えます。
テスト用ファイルの追加
vol1からvol1_dst_dstで差分がある場合のSnapMirrorの動きが気になってきました。
vol1にテスト用ファイルを追加します。

重複排除量やaggregateレイヤーでのデータ削減量に大きな変化はありませんでした。
また、DisableだからかSnapMirror転送後にvol1_dst_dstでのStorage Efficinecyは実行されていないようでした。SnapMirror initializeやresync後にStorage Efficiencyを有効化した方が良いかもしれません。

カスケードSnapMirrorでStorage Efficinecyを維持できる条件を整理する
svm と svm2 のボリューム間のSnapMirror initialize
カスケードSnapMirrorでStorage Efficinecyを維持できる条件を整理したいと思います。
先ほどの検証ではvol1 -> vol1_dst -> vol1_dst_dstとカスケードSnapMirrorを2回繰り返すと、vol1_dstで実行したStorage Efficiencyの効果をvol1_dst_dstで維持することができました。
ここでvol1_dst -> vol1_dst_dstのみ転送した場合の挙動が気になりました。
まず、svm と svm2 のボリューム間のSnapMirror relationshipのinitializeを行います。
転送元のボリュームはvol1で、転送先のボリュームはvol1_dst2と新しいものを用意します。

vol1_dst2で実行したStorage Efficiencyの重複排除はvol1_dst2_dstに引き継がれていませんが、Space Saved by Aggregate Data Reductionが7.90GBから10.15GBと2.25GBほど増加しています。
また、Auto Adaptive Compressionは3.71GBと表示されています。
そのため、aggregateレイヤーのデータ削減効果はしっかりと維持できていそうです。

重複排除量もaggregateのデータ削減量も変化ありません。
また、vol1_dst2にもvol1_dst2_dstにもSnapshotは追加されていません。
そのため、Storage Efficiencyによる重複排除の最終的な転送先に反映するためにはvol1 -> vol1_dst -> vol1_dst_dstとカスケードSnapMirrorを2回繰り返す必要があるようです。

vol1_dst2_dstで重複排除が効いていますね。
そのため、Storage Efficiencyによる重複排除の最終的な転送先に反映するためにはvol1 -> vol1_dst -> vol1_dst_dstとカスケードSnapMirrorを2回繰り返す必要があることが分かりました。
vol1_dst2_dst のSnapshotを削除する
vol1_dst2_dstのSnapshotを削除していってボリュームやaggregateの使用量の変化を確認します。
SnapMirrorをカットオーバーします。

Snapshotを削除したことにより、以下のように各種値が変化していました。

3.85GBのSnapshotを削除したのに応じてボリューム、aggregateの物理使用量が減っていることが分かりますね。
NFSクライアントからも確認します。

移行や二次バックアップに
Amazon FSx for NetApp ONTAPでカスケードSnapMirrorを試してみました。
移行や二次バックアップに役立ちそうですね。特にオリジンの操作を行いたくない時には使っていきたいです。
この記事が誰かの助けになれば幸いです。
