今天早上我遇到了严重的问题。我通过 Teamviewer 远程连接到实验室中的 Ubuntu 桌面以完成机器学习模型的训练,并在一周内向我的主管展示一些结果。
在某一点上,我的脚本应该pickle
转储一些数组列表的大文件(大约 3GB),所以我让脚本运行了一夜。今天早上,我远程连接检查,发现脚本停止运行并显示一条No space left on device
消息。
我怀疑系统转储了太多tmp
文件,所以我reboot
通过终端执行,迫使系统重新启动(我的错)。
不幸的是,重新启动后,我只能看到黑屏(光标闪烁,见下图)。可能系统挂了,无法进入登录阶段,所以我看不到输入登录屏幕来输入密码。
有没有办法可以安全地重新启动系统?请问有什么帮助吗?

现在可以访问 GRUB 菜单。我选择了这个Drop to root shell prompt
选项。但是大约 5 分钟,我收到的消息如下(光标闪烁)

步骤1:
在恢复模式下,在#
提示下,执行以下操作...
sudo pico /etc/fstab
#编辑这个文件
改变这个:
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0
对此:
#/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0
Control+o然后Enter# 写出文件
Control+ x# 退出 pico 编辑器
reboot
第2步:
Either TeamViewer in, or boot to a Ubuntu Live DVD/USB, and start the Disk Usage Analyzer
application (this may be called something different on Lubuntu). A few clicks, and you can determine what's eating up your hard disk, and we can take the next step.
Disk Usage Analyzer
is accessed from the GUI, but on Lubuntu it may not be installed by default, and you don't have the disk space to install it. The Ubuntu Live DVD/USB is what you used to install Lubuntu originally. If you don't have it any more, download the Ubuntu (not Lubuntu) image and create a Ubuntu Live DVD/USB which will have Disk Usage Anayzer
already installed on it.
Step #3:
To try an clear a little disk space...
In the terminal
...
dpkg -l linux-* | grep -e ii | grep -e "-76"
You should end up with 4-5 filenames. If it's more, then stop and tell me what you see. Then do...
sudo dpkg -P put_one_filename_here
并对之前显示的 4-5 个文件名重复此操作。
您现在可以正常启动了。清理工作仍在继续。
第四步:
让我们确保您没有文件系统问题...
terminal
按Ctrl+ Alt+打开一个窗口Tsudo fdisk -l
sudo fsck -f /dev/sdXX
,替换sdXX
为您之前找到的数字fsck
如果有错误,请重复该命令reboot
