さて、ここにいくつかの問題があります。 Linux環境が初めてで、助けが必要です。誰かが約200 GBのパーティションで構成された2.7 TBのRAIDアレイがありますが、実際には2.2 TBのように大きくする必要があります。パーティションを大きくする方法は？
そして、冗長な2.2TBパーティションがあるようです。
ディスク219.9 GBのパーティションを2.2 TBにする必要がありますが/dev/mapper/vg_orchestrator1-lv_home、そのパーティションのサイズを変更する方法、または新しいコンテンツを作成してコンテンツをコピーする必要があるかどうかはわかりません。
以下は、私が実行したいくつかのコマンドに関する情報です。
