我正在尝试向我的根分区添加空间，但我真的不确定最安全的方法。我读过这个主题，我可以在不卸载并重新安装 Linux（或丢失数据）的情况下调整根分区的大小吗？ 但我认为这些信息与我的系统不符。
任何帮助将不胜感激。另外，在那篇文章中，F1234K 询问有关如何阅读以学习这些内容的建议，但没有人回复。我也对有关该主题的一些学习材料非常感兴趣。
谢谢！
编辑：我应该补充一点，我的目标是从 sdb6 中取出 20 GB 并将其放入 sdb1 中。 sdb6 是 sdb2 的逻辑卷。

答案1
如果仔细操作，您可以使用gparted安全地调整分区大小。
您应该启动到实时映像，因为您无法调整已安装分区的大小，并且确保您有有效的数据备份！
答案2
值得一提的是，您也可以将大目录移动到另一个分区上（例如，通过在 /var 上安装 /dev/sdb3）。但要小心，因为如果某些数据无法访问（即，如果将它们移动到启动时未安装的分区上），系统可能无法启动。
