Amazon FSx for NetApp ONTAPにおけるSnapMirrorのTemperature Sensitive Storage Efficiency (TSSE) の挙動を確認してみた
SnapMirrorをする前にTSSEを効かせることが望ましい
2023.11.26SnapMirrorの転送先ボリュームで転送完了後に追加の重複排除や圧縮などが効くのか気になる
こんにちは、のんピ(@non____97)です。
皆さんはSnapMirrorの転送先ボリュームで転送完了後に追加の重複排除や圧縮などが効くのか気になったことはありますか? 私はあります。
SnapMirrorを使うことで、転送元ボリュームのStorage Efficiencyによる重複排除や圧縮などのデータ削減の効果を維持したまま転送することが可能です。
それでは、その転送先のボリュームで追加の重複排除や圧縮はできるのでしょうか。
KBには転送先と転送元がTSSEの場合は追加の重複排除や圧縮が効くとは明記されていません。
- SnapMirrorは、デスティネーションに追加の形式の圧縮が適用されないかぎり、ソースのストレージ効率（重複排除、圧縮、コンパクションなど）を維持します。ただし、温度対応のStorage Efficiencyは除きます
次の表に、ソースボリュームとデスティネーションボリュームのStorage Efficiencyの組み合わせと転送結果を示します
- 重複排除（D）-インラインまたはバックグラウンド/ポストプロセス
- アダプティブ圧縮（CA）-インラインまたはポストプロセスです
- 二次圧縮（cs）-インラインまたはポストプロセスです
- 温度依存Storage Efficiency（TSSE）- ONTAP 9.8以降（AFF プラットフォーム）
追加の重複排除や圧縮ができるのであれば、以下記事で紹介しているように「重複排除を効かせた状態で移行をしたい。ただ、ほとんどのデータをキャパシティプールストレージに持っていきたい」という要望がある場合において役立ちます。
具体的には、現行ファイルサーバーがONTAPである時、現行ファイルサーバーから1台目のAmazon FSx for NetApp ONTAP(以降FSxN)へSnapMirrorを使うことが可能になります。もし、追加の重複排除や圧縮が効かない場合はいくら1台目のFSxNで寝かせていても時間の無駄となってしまいます。
実際にSnapMirrorの転送先ボリュームで追加の重複排除や圧縮が効くのかどうか確認してみました。
なお、FSxNにおけるTSSEの仕様はなかなか安定していません。突如として叩けなかったコマンドが叩けるようになったり、見えなかった情報が見えるようになったりします。検証結果は2023/11/21時点のONTAP 9.13.1P5時点のものです。今後挙動が変わる可能性も十分にあるため、参考にする際はご注意ください。

いきなりまとめ
- 転送先ボリュームがTSSEであっても、SnapMirrorの転送先ボリュームで転送完了後に追加の重複排除や圧縮を行うことは可能
- ただし、Snapshotによってデータブロックがロックされるため、物理的なデータ使用量は変化しない
- 物理的なデータ使用量を削減したい場合はSnapMirror relationshipを解除した上で、転送先ボリュームのSnapshotを削除する必要がある
- SnapMirrorで転送されたSnapshotにおいて、重複しているデータブロックがある場合は、転送完了後に重複排除の処理が動作し、即座に物理的なデータ使用量が削減される (SnapMirrorの初期転送時は動作しない)
- FSxNにおいてTSSEはデフォルトで有効
- ただし、ポストプロセスの圧縮(Inactive data compression)は無効となっている
- SnapMirrorの転送元ボリュームでTSSEが有効であれば、転送先ボリュームでTSSEを有効にしていなくともTSSEによるデータ削減は維持された状態で転送される
- ただし、転送先ボリュームでTSSEを有効化しなければ、手動でTSSEを実行することはできない
- 転送先のボリュームでTSSEを有効化するのはSnapMirrorの初期化が完了した後である必要がある
- SnapMirrorの転送先ボリュームのポストプロセスの圧縮(Inactive data compression)が有効かどうかは転送元ボリュームに依存する
- 転送先ボリュームで有効化していても、転送元ボリュームで無効化されている場合は、転送先ボリュームの Inactive data compression は無効になる
- 逆に転送先ボリュームで無効していても、転送元ボリュームで有効化されている場合は、転送先ボリュームの Inactive data compression は有効になる
- そのため、転送元ボリュームで Inactive data compression を有効にすることが望ましい
- 転送先ボリュームと転送元ボリュームの Inactive data compression の閾値はそれぞれ別の値を設定することが可能
- 2023/11/21時点の ONTAP 9.13.1P5 の FSxN の inactive-data-compression の実行間隔は24時間で固定
- 開始する時間はボリュームごとに異なる
- 確認した限り、ファイルシステムやSVM、ボリュームが作成完了した時間や Inactive data compression を有効化した時間とは関係がない
- Inactive data compression の閾値はデフォルト14日
- 設定できるミニマムは1日であるため、基本的に1日以上は転送されたデータを寝かせる必要がある
- 実行間隔である24時間を待てない場合はvolume efficiency inactive-data-compression startを実行すると、直ちに閾値で指定した日数経過したデータ圧縮処理が開始される
volume efficiency inactive-data-compression startに-inactive-days 0オプションを付与することで1日待たなくともデータ圧縮処理を開始することが可能- Tiering Policy Allのボリュームに対して
volume efficiency inactive-data-compression startを叩くことはできない
volume efficiency start -scan-old-dataを実行しても、Inactive data compressionの処理は実行されない- 別々で実行する必要がある
- SnapMirrorの転送先ボリュームでは
volume efficiency startを叩く際は-scan-old-dataのオプションを追加する必要がある
- SnapMirrorの転送先ボリュームを書き込み可能にしたタイミングで、Inactive data compressionの閾値はデフォルトのものになる
snapmirror break前にInactive data compressionの閾値をカスタマイズしている場合は注意が必要
Temperature Sensitive Storage Efficiency (TSSE) とは
Temperature Sensitive Storage Efficiency (TSSE)とはボリュームのデータのアクセス頻度に応じて圧縮レベルを変更する仕組みです。
さらにONTAP 9.8ではTSSE （Temperature Sensitive Storage Efficiency）が搭載され、書き込まれた当初はパフォーマンスを重視して8KB単位でインライン圧縮し、しばらくアクセスがないと32KB単位に再圧縮することで、より圧縮率を上げることができるようになりました。
データが書き込まれた際(インライン)と、その後(ポストプロセス)で実行されるデータ削減処理が異なります。
- データ書き込み時は以下の順番で処理が行われる
- ゼロブロック重複排除
- インライン重複排除
- インライン圧縮
- コンパクション
- ポストプロセスの重複排除と圧縮は別々のタイミングで行われる
- ポストプロセス重複排除 : Changelog が閾値(デフォルト20%)を超えたタイミング
- ポストプロセス圧縮(Inactive data compression) : 設定した閾値(デフォルト14日)経過したデータブロックをCold Dataとして判定したタイミング
こちらのTSSEの詳細な説明は別の記事にて行う予定です。
やってみる
検証環境
検証環境は以下のとおりです。
FSxNファイルシステムを2つ用意して、FSxN1からFSxN2のボリュームにSnapMirrorします。
SnapMirrorの転送元ボリュームでテストファイル作成前の状態の確認
SnapMirrorの転送元ボリュームでテストファイルを作成する前にaggregateやボリュームの情報を確認しておきます。
なお、当たり前のように権限レベルをdiagに設定していますがマネしないでください。この権限は非常に強い権限であるため、基本的にはサポートの指示を受けた時に使用するものです。今回はできるだけ低レイヤーの情報も欲しかったのでdiagで作業しています。

要点をざっとまとめると以下のとおりです。
- aggregateの空き容量は860.6GB
- 重複排除や圧縮されているデータは存在しない
- ボリュームのStorage Efficiency Modeが
efficientであることからTSSEは有効 - 以下の処理は有効
- インライン圧縮
- インライン重複排除
- ポストプロセス重複排除
- Inactive data compressionは無効
TSSEのキモであるInactive data compressionはデフォルトで無効のようです。そのためポストプロセスの圧縮は動作しません。TSSEの本来の挙動をして欲しい場合は手動でInactive data compressionを有効にしましょう。

要点は以下のとおりです。
- aggregateの空き容量は859.5GBとわずかに減少
- Tiering Policy All であるため、SSD(Performance Tier)の使用量は1.21GBしか増えていない
- 代わりにキャパシティプールストレージ(FSxFabricpoolObjectStore)の使用量は5GB増えている
- 重複排除や圧縮されているデータは存在しない
- Last Operation Beginの時刻が変動していないことから、重複排除や圧縮などTSSEの処理自体が行われていない
- Inactive data compressionは動作していない
重複排除や圧縮を効かせずにキャパシティプールストレージにデータを移動することができました。
次に、作成したテスト用ファイルを9個コピーします。
コピーする際は一つひとつキャパシティプールストレージに流し切ったことを確認してコピーするのではなく、4多重で並列に行います。

要点は以下のとおりです。
- aggregateの空き容量は859.5GBと変わらず
- 5GiBのファイルを9つコピーしたため45GiB増えている論理的なサイズは50GBになっている
- Tiering Policy All であるため、SSD(Performance Tier)の使用量は255.3MB
- 代わりにキャパシティプールストレージ(FSxFabricpoolObjectStore)の使用量は29.59GBに増えている
- 重複排除によって20.66GBデータが削減されている
- 圧縮によるデータ削減は発生していない
- Inactive data compressionのステータスがFAILUREとなっている
- ステータスが無効であるため、動作していないだけで処理の開始を行おうとしたと想定
Tiering Policy AllのボリュームでTSSEを手動実行
次に手動でTSSEを動作させます。
ほとんどのデータがキャパシティプールストレージです。TSSEはFabricPoolのローカル(FSx for ONTAPでいうところのプライマリストレージ)のみサポートしています。
Temperature-sensitive storage efficiency
Beginning in ONTAP 9.8, temperature-sensitive storage efficiency (TSSE) is available. TSSE uses temperature scans to determine how hot or cold data is and compresses larger or smaller blocks of data accordingly — making storage efficiency more efficient.
Beginning in ONTAP 9.10.1, TSSE is supported on volumes located on FabricPool-enabled local tiers (storage aggregates). TSSE compression-based storage efficiencies are preserved when tiering to cloud tiers.
試しに、既存のデータに重複排除や圧縮などが効くようにvolume efficiency startの-scan-old-dataを指定した上でコマンドを叩きます。
ドキュメント通りならデータ削減量は変わらない想定です。
せっかくなので、Inactive data compressionが連動して動作するかもチェックします。
事前準備としてInactive data compressionを有効にします。

Change logが37%と20%を超えていたからか、既にTSSEの処理が走っていました。
実行結果を確認しても重複排除や圧縮の効果は変わりありませんでした。念の為もう一度volume efficiency start -volume vol1 -scan-old-dataを叩きましたが、結果は変わりありませんでした。
ということで、やはりキャパシティープールストレージのデータブロックに対して追加のデータ削減効果を得ることはできないようです。
手動でInactive data compression
手動でInactive data compressionもしてみましょう。
::*> volume efficiency inactive-data-compression start -volume vol1 Error: command failed: Failed to start inactive data compression scan on volume "vol1" in Vserver "svm". Reason: "CA tiering Policy is all"
「Tiering Policy AllであるためInactive data compressionのスキャンは開始に失敗した」とエラーになりました。
SnapMirror relationshipの作成
SnapMirror relationshipの作成をします。
SnapMirrorの詳細な説明は以下記事をご覧ください。
まず、クラスターピアリングをします。

Compressionだけでなく、Inline DedupeやInline Compressionも無効になっていますね。
Storage Efficiency Modeも-で、そもそもState: Disabledとなっています。
また、Inactive data compression の情報を確認することはできませんでした。
手動でTSSEを有効化できるか確認してみます。
::*> volume efficiency modify -volume vol1_dst -storage-efficiency-mode efficient -inline-dedupe true -data-compaction true Error: command failed: The "-storage-efficiency-mode" parameter is only supported on RW volumes.
DPボリュームでは-storage-efficiency-modeをすることはできないようです。
以下KBにも転送先ボリュームでTSSEを有効にする必要がないと記載されているので、このまま検証を進めます。
ONTAP のリリースおよびプラットフォームでサポートされている場合、SnapMirrorデスティネーションボリュームでTSSEを有効にするための手順は必要ありません

要点は以下のとおりです。
- 転送元ボリュームの重複排除や圧縮の内容が維持されている
- 転送先ボリュームのStorage Efficiency Modeが
efficientになった- ただし、ステータスはdisableのまま
- Inactive data compressionも有効になった
確かにTSSEを転送先ボリュームで有効化しなくとも重複排除や圧縮の内容が維持されています。
転送先ボリュームで手動でTSSEを実行
次に転送先ボリュームで手動でTSSEを実行します。

ポイントは以下になります。
Physical Space Used for All Volumesが29.68GBから14.66GBと大幅に減っている- ただし、
Physical Space Used by the Aggregateは30GBでほとんど変わっていない - 代わりに
Physical Size Used by Snapshot Copiesが337.0MBから15.48GBと増えている - Inactive data compression は連動して動作しない
これは、重複排除によりアクティブファイルシステム(AFS)上では参照するデータブロック数が少なくなったが、Snapshotでは変わらず重複データ分のデータブロックを保持していることによるものだと考えます。
Snapshotの情報も確認してみるとサイズは15.48GBでした。

SnapshotのサイズはおおよそAFSやSnapshotとの差分量で考えて良いと思います。今回は他のSnapshotは存在していないため、15GBは手動によるTSSEによって重複排除された影響によるAFSとの差分量であると考えられます。
ただし、Snapshotでは重複排除によって削減されたデータも保持しているため、物理的なデータ量は変わっていません。
こちらの挙動は以下NetAppのKBにも記載されています。
いいえ。 ONTAP では、アクティブなファイルシステム（ AFS ）にあるブロックにのみ効率化機能が適用されます。
TR(Technical Report)にも「Snapshot内のブロックはロックされて重複排除できない」、「スペースの節約をしたい場合はSnapMirrorを実行する前に重複排除をするべき」と記載されています。
SnapMirror creates a Snapshot copy before performing an update transfer. Any blocks in the Snapshot copy are locked and cannot be deduplicated. Therefore, if maximum space savings from deduplication are required, run the dedupe process before performing SnapMirror updates.
TR-4015: SnapMirror Configuration and Best Practices Guide for ONTAP 9.11.1
SnapMirrorの転送元がTiering Policy Noneであれば、事前にTSSEを効かせた上で転送したいですね。
SnapMirrorの転送先ボリュームでInactive data compression の動作確認
TSSEによるポストプロセス重複排除はSnapMirrorの転送先ボリュームで動作することを確認できたので、次はInactive data compression の動作確認をします。
volume efficiency inactive-data-compression modifyで1日経過したデータをCold Dataとして判定し、圧縮するように設定します。
::*> volume efficiency inactive-data-compression modify -volume vol1_dst -threshold-days 1 -threshold-days-min 1 -threshold-days-max 1
この状態で一日ほど待ってみます。

Time since Last Inactive Data Compression Scan ended(sec)が更新されていることから、気づかないうちに実行されていました。
ただし、Number of Compression Done Blocksが0であることから特に圧縮はされていなさそうです。そもそも、Number of Cold Blocks Encounteredも0であることからColds Dataと判定されたブロックが存在しない。
EMSイベントも確認しましたが、Inactive data compressionの形跡はありませんでした。

INFORMATIONAL Nblade.nfsCredCacheFlushed: When the administrator modifies the "extended-groups-limit" option or "auth-sys-extended-groups" option using the "vserver nfs modify" command, the entire credential cache is flushed that holds credentials on connections that use mixed-mode security style volumes or RPCSEC_GSS authentication or extended groups over AUTH_SYS. This makes subsequent operations on such connections slower for a short while, until the credential cache is repopulated. The value of "auth-sys-extended-groups" option is 0 (1:enabled, 0:disabled). The value of "extended-groups-limit" option is 32.

Number of Cold Blocks Encounteredは8432464であるため、Cold Dataとして判定されたデータブロックは8,432,464 × 4KiB / 1,024 / 1,024 ≒ 32.16GiB分判定されていそうです。(ONTAPのデータブロックは4KiB単位)
これは物理データ量のサイズとおおよそ一致しているので、ほぼ全てのデータをCold Dataとして判定したと考えます。
ただし、Number of Compression Done Blocksが0であることから圧縮はできていません。また、Incompressible Data Percentageを確認すると97%でした。
Inactive data compressionは32KB単位で圧縮します。通常のSecondary Compressionも32KB単位で圧縮しますが、圧縮率が25%以上なければ実際の圧縮は行いません。
重複排除がかかっている状態で転送されたのかが良くないのか、それともテストファイルが/dev/urandomで生成したファイルであるのが良くないのかどちらかが原因なような
再トライ (1回目)
テスト用ファイルの準備
再トライします。
先の検証では、重複排除がかかっている状態で転送されたためInactive data compressionによるデータ圧縮が上手くいかなかったと仮定して、今回は重複排除を効かせないようにして転送をします。
そのためファイルはコピーする際は、前にコピーしたファイルのデータがキャパシティプールストレージに流し切られてから行います。
適当に20個ほどコピーしました。

要点は以下のとおりです。
Logical Size Used by Snapshot Copies: 151.7GBやLogical Space Used for All Volumes: 100.2GBと論理サイズは増えている- ただし、
Physical Size Used by Snapshot Copies: 15.48GBやPhysical Space Used for All Volumes: 14.65GBとSnapMirrorの再同期前後と比較して物理サイズは変わっていない - SnapMirror再同期で転送されたSnapshotのサイズが180KBと非常に小さい
- つまりは、AFSとの差分がほとんどない
- 重複排除によって削減されたデータ量が35.57GBから85.57GBと、転送した50GB分増えている
これは再同期時に追加されたファイルが全て最初に転送したSnapshotに含まれるファイルと同じであるため、このように重複排除されたのだと考えます。
Snapshotで保持しているデータブロックは重複排除によって解放されないと紹介しましたが、SnapMirrorで転送されたSnapshot間で行われる重複排除ではデータブロックを解放してくれるようです。
SnapMirrorの転送先ボリュームでInactive data compression の動作確認
SnapMirrorの転送先ボリュームでInactive data compression の動作確認を行います。
重複排除によって再同期で転送したデータブロックのほとんどが重複排除されてしまったので、同じ結末を迎えるような気はしています。
SnapMirror後の重複排除が完了してから1日経っても、以下のように圧縮されたデータブロックはありませんでした。

やはり、Number of Compression Done Blocksが0となってしまい、圧縮できていません。
これはテストファイルが/dev/urandomで生成したためなような気がしてきました。
再トライ (2回目)
テスト用ファイルの作成
テストファイルを変更して再々トライします。
ボリュームはvol2と新しく用意しました。
テストファイルはAmazon Linux 2023の/usrとします。このディレクトリを10個コピーします。
コピーする際は、できるだけ重複排除が事前にかからないように前にコピーしたファイルがキャパシティプールストレージにTieringされたことを確認しながら行います。

要点は以下のとおりです。vol1_dstと変わりありません。
- 転送元ボリュームの重複排除や圧縮の内容が維持されている
- 転送先ボリュームのStorage Efficiency Modeが

- Inactive data compressionも有効になった
転送先ボリュームでTSSEとInactive data compressionの有効
転送先のボリュームでTSSEとInactive data compressionの有効化を行います。

テスト用ファイルの追加
このタイミングで転送先ボリュームで手動でTSSEやInactive data compressionをしても良いですが、SnapMirrorで転送されたSnapshot間で重複排除された時に、自動で重複排除の処理が走ったことが気になりました。
最初に転送したSnapshotと重複しないデータブロックを保持している場合についても、自動で重複排除の処理が走ろうとするのか確認してみます。
重複排除処理がかかるのであれば、再同期したSnapshot内での重複排除が効くのではないかという淡い期待もしています。
テスト用ファイルとして/etcをvol2にコピーします。
$ for i in `seq 1 100 `; do sudo cp -rp /etc /mnt/fsxn/vol2/etc"$i" sleep 5 done; cp: cannot create regular file '/mnt/fsxn/vol2/etc49/pki/ca-trust/extracted/pem/directory-hash/Autoridad_de_Certificacion_Firmaprofesional_CIF_A62634068_1.pem': No space left on device cp: cannot create symbolic link '/mnt/fsxn/vol2/etc49/pki/ca-trust/extracted/pem/directory-hash/3bde41ac.1': No space left on device cp: cannot create symbolic link '/mnt/fsxn/vol2/etc49/pki/ca-trust/extracted/pem/directory-hash/626dceaf.0': No space left on device cp: cannot create symbolic link '/mnt/fsxn/vol2/etc49/pki/ca-trust/extracted/pem/directory-hash/c559d742.0': No space left on device cp: cannot create regular file '/mnt/fsxn/vol2/etc49/pki/ca-trust/extracted/pem/directory-hash/GTS_Root_R3.pem': No space left on device
vol2のボリュームサイズを拡張していなかったのでディスクフルとなってしまいました。
vol2のボリューム情報とSnapshotの情報を確認しておきます。

要点は以下のとおりです。
- SnapMirrorの転送完了後にTSSEが動作している
- TSSEにより830.5MBのデータが処理対象となっている
- 転送元ボリュームの
sis-space-savedが638.9MBに関わらず、転送先ボリュームは1.39GBであることから転送先で追加の重複排除が効いていることが読み取れる - SnapMirrorの再同期前後と比較して
Total Physical Usedは大きな変動はしていない - 有効にしていたInactive data compressionが無効化されている
どうやらSnapMirrorの再同期後は自動で転送されたSnapshotに対してTSSEが効くようです。これはありがたい挙動ですね。
ただし、気になるのは「有効にしていたInactive data compressionが無効化されている」点です。
もしかしたらSnapMirrorの転送元のステータスの影響を受けるかもしれません。
実験してみましょう。
vol2のInactive data compressionを有効化します。

trueになっていますね。そのため、Inactive data compressionはSnapMirrorの転送元のステータスの影響を受けるようです。
ちなみに、MirrorAllSnapshotsのSnapMirror relastionsipでSnapMirrorの再同期を行なったため、SnapMirror relastionshipで転送されたSnapshotは削除されています。

volume show-footprintから確認できるAuto Adaptive Compressionが7.94GBとなっていますね。ということでSnapMirrorの転送先ボリュームでInactive data compressionをかけるのは可能です。
なお、そのほかのコマンドで確認できるCompressionは軒並み0になっています。
以下のKBのとおりvolume show-footprintで確認できることは知っていましたが、aggr show-efficiencyでも確認できないのは意外です。
SnapMirrorの転送先ボリュームを書き込みできるように修正
TSSEによる重複排除やInactive data compressionがSnapMirrorの転送先ボリュームで動作することを確認しました。
ただし、AFSで削減されたデータブロックをSnapshotがロックしているため、物理的な使用量は変わっていません。
そこで、Snapshotを削除してみて、確かに物理的な使用量が削減されることを確認してみます。
その下準備としてSnapMirrorの転送先ボリュームを書き込みできるように修正します。

SnapMirrorの転送先ボリュームを書き込みできるように修正した後、SnapMirrorの転送先ボリュームのaggregateやボリュームのサイズを確認しましたが、特に変わりありません。
ただし、Efficiency Policy Nameにautoが設定されているのと、Inactive data conmpressionがの閾値がデフォルトのものに変わっていることを確認できました。

SnapMirrorの転送先ボリュームでInactive data compressionの閾値をカスタマイズしていた場合は要注意ですね。
転送先ボリュームをジャンクションパスにマウントします。

マウント後、ボリューム内のディレクトリを確認します。

aggregateの空き容量が813.3GBから824.6GBへと大幅に増えています。TSSEを実行前のSnapshotがある場合、Snapshotを削除すれば物理的な空き容量を確保することが確認できました。
残りのsnapshot 削除後の状態をNFSクライアントからも確認します。

SnapMirrorをする前にTSSEを効かせることが望ましい
Amazon FSx for NetApp ONTAPにおけるSnapMirrorのTemperature Sensitive Storage Efficiency (TSSE) の挙動を確認してみました。
SnapMirrorの転送先で追加のTSSEが効くことを確認できました。ただし、Snapshotがデータブロックをロックしている関係上、TSSEによる物理的なデータ削減効果を得るには一手間費用です。
本来であれば、SnapMirrorをする前に転送元でTSSEを効かせることが望ましいです。まずはそちらができないか検討すると良いでしょう。
また、SnapMirrorのStorage Efficiencyの関係性については以下KBによくまとまっています。こちらについてもご覧ください。
この記事が誰かの助けになれば幸いです。
