私のUbuntu 14.04サーバーでRAID5設定を行います。 2つの4TB WD NASドライブがあり、別のドライブを購入しました。ただし、pvsを使用してシステム上でこれらのドライブを見つけようとすると、3つのドライブ（私のシステムドライブと2つの追加のドライブ）だけが見つかります。

したがって、sdcドライブはPVSに表示されません。 RAIDを実行する前に心配する必要がありますか、それとも続行する必要がありますか？
よろしくお願いします.:)
答え1
pvs物理ドライブはリストされておらず、物理ボリュームです。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
（ドライブを分割した場合は後者）。
