在文件名选项卡完成后，我收到来自 bash 的错误 No space left on device。
当我试图找出是什么耗尽了我的空间时，正如类似问题所建议的那样，我对 df -ah 结果感到困惑。我的电脑有 220GB 磁盘，但似乎只使用了 66GB。
哪里有问题？ var/lib 中有很多 docker 镜像吗？我应该把它们移到其他地方吗？

答案1
嗯，看看清单。您拥有的基本分区是这两个：
Filesystem Size Used Avail Use% Mounted on
/dev/nvme0n1p7 34G 32G 0 100% /
/dev/nvme0n1p9 173G 16G 149G 10% /home
即，您有大约 170 GB 的单独空间/home，但其他所有内容（包括/var）都在 中/，而只有 34 GB。
对已安装的系统重新分区可能很困难（除非您使用 LVM，但您没有使用 LVM），但您可以尝试看看是否有一些大型数据集可以移动到/home，例如那些映像。您还可以运行从/var/whatever到 例如 的符号链接/home/var/whatever（或类似的绑定安装），以便数据在 下的预期位置仍然可见/var。
答案2
您的根文件系统已满，临时目录也已满。许多脚本和程序都需要一些空间来存放工作文件，甚至锁定文件。当 /tmp 不可写时，就会发生不好的事情。
