Linux
如何在 Debian 中調整根分區的大小？
我正在嘗試向我的根分區添加空間，但我真的不確定最安全的方法。我已經閱讀了這個文章，我可以在不解除安裝和重新安裝 Linux（或失去數據）的情況下調整根分區的大小嗎？ 但我認為這些資訊與我的系統不相符。
任何幫助將不勝感激。此外，在那篇文章中，F1234K 要求提供關於良好閱讀的建議以學習這些內容，但沒有人回复。我也會對該主題的一些學習材料非常感興趣。
謝謝！
編輯：我應該補充一點，我的目標是從 sdb6 中取出 20 gb 並將其放入 sdb1。sdb6 是 sdb2 的邏輯卷。

如果仔細完成，您可以使用
gparted安全地調整分區大小。您應該啟動到實時映像，因為您無法調整已安裝分區的大小，並確保您擁有有效的數據備份！
值得一提的是，您也可以將大目錄移動到另一個分區上（例如，通過在 /var 上掛載 /dev/sdb3）。不過要小心，因為如果某些數據無法訪問（即如果您將它們移動到未在啟動時安裝的分區上），系統可能無法啟動。
