CentOS 7サーバーはLUKSと/boot。/boot/efiその後、大規模なLUKS暗号化残りのパーティション（1.8TB）に追加のパーティション分割が必要でした。 CentOS 7のインストール中にハードドライブの必要な部分をLUKS暗号化できましたが、今では大規模なLUKSパーティション内に追加のパーティションを作成することはできません。 大規模（1.8TB）LUKS暗号化パーティションにパーティションを作成するには？ これまでに試した実際の端末ログは次のとおりです。

@TomHuntの提案に従って、コンピュータにCentOS 7を再インストールしました。この時間を活用してくださいLVM大規模な 1.8 TB パーティションを含むすべての関連パーティションのパーティションタイプ。しかし、1.8TBパーティションを準備しようとすると、parted同じエラーが発生します。rm 3最新の試みの端末ログは次のとおりです。
