磁盘空间被占用和丢失

772

我的根驱动器有 143.9 GB 的空间。我有一个 60GB 的 vbox vdi 和操作系统，它应该是另一个 30 GB...给我留下 54GB 的可用空间。

问题：
今天早上我随机收到根驱动器的“磁盘空间已满”错误消息。

我立即删除了一些旧日志的演出......但是比那个空间吃掉（未释放）我仍然得到错误......

我找不到 54GB 的磁盘空间。

找到问题了……又是一个“鬼坐骑”……

我启动进入 LiveUSB 会话并运行上述命令来检查我的磁盘...所有命令都表示磁盘“正常”但已满。

仍在 liveUSB 会话中时，我通过 nautilus 挂载了我的磁盘，但在终端中我再次运行

（作为我在 liveUSB 会话中的06ed954b-3750-49d3-b02d-43943788697f挂载根分区。/

这49G /media/ubuntu/06ed954b-3750-49d3-b02d-43943788697f/media/user/external_drive 是不可能的，因为我没有在 liveUSB 会话期间安装它。

所以我rm -rf /media/ubuntu/06ed954b-3750-49d3-b02d-43943788697f/media/user/external_drive

很快！

49GB 的空间已经归还给我，我终于可以完成一些真正的工作了。

因此，在不推荐的硬重启后，似乎有两种可能的“幽灵挂载”类型。

我在这里遇到的“路径错误”幽灵挂载，现在是“磁盘空间”幽灵挂载（请注意，我的脚本都没有吓坏，因为即使“幽灵坐骑”存在）

在 liveUSB 会话中，gparted 和其他应用程序现在确认我的可用磁盘空间。

磁盘空间被占用和丢失

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
