CHECK 1OTHER 52

`V2` の `linked-clone` ボリュームでは、旧方式から新しいアーキテクチャへの切り替えに伴って扱いが変わります。`v1.12.0` 以前に作成したボリュームを使用している環境では、アップグレード後の操作範囲に影響します。

影響確認 (1)

  • breakingV2 の linked-clone ボリュームをレガシー扱いに変更

    v1.12.0 以前に作成した V2 の linked-clone ボリュームがある場合に適用されます。

    v1.12.0 以前に作成された V2 の linked-clone ボリュームは、v1.12.1 からレガシーとして非推奨になります。新しい linked-clone アーキテクチャは旧方式と互換性がないため、アップグレード後に実行できる操作は切り離しと削除に限られます。
