Sudopvdisplayのときにドライブが表示されない
私はubuntu14.04サーバーでRAID5セットアップを行います。私は24 TB WD NASドライブを持っていて、別のドライブを購入しました。しかし、pvsを使用してシステム内でそれらのドライブを見つけようとすると、3つしか見つかりません。ドライブ（私のシステムドライブと2つの追加ドライブ）。

したがって、sdcドライブはpvsに表示されません。これはRAIDを作成する前に気になることですか、それとも先に進みますか？
前もって感謝します.. ：）
pvsは物理ドライブを一覧表示せず、物理ボリュームを一覧表示します。 pvs ’出力に表示される前に、物理ボリュームを作成する必要があります。
pvcreate /dev/sdc
または
pvcreate /dev/sdc1
（ドライブをパーティション分割した場合は後者）。
