ボリュームシステム「ルート」のディスク容量が不足しています。

Debian 7を1TBドライブにインストールし、Debianに自動的にパーティションを設定させ、LVMを選択してOwnCLoudをインストールしました。ルートディスクに空き容量がなく、空き容量が35MBしかありません。クラウドストレージにアクセスできなくなり、Apache2も再起動する必要がありますか？というメッセージが表示されるまで、すべてがうまく機能しました。自動的に起動します。 Apacheを再起動した後、クラウドにアクセスできますが、クラウドはデータベースにアクセスできません。プログラムを実行できないのは、スペース制約によるものです。このボリュームをどのように増やすことができますか？ Gpart liveの使用に疲れていますが、ボリュームを追加できません>ここに私のfdisk -lリストがあります！
