Errno 28 设备上没有剩余空间，尽管还有空间

你好，我对 ubuntu 还很陌生，今天当我尝试打开 jupyter notebook 时出现了以下错误：

myname@My-Laptop:~$ jupyter notebook
[I 2022-08-08 07:58:41.188 LabApp] JupyterLab extension loaded from /home/myname/.local/lib/python3.8/site-packages/jupyterlab

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

我很困惑为什么会出现此错误，因为我的笔记本电脑有足够的存储空间。我使用df -h并得到以下结果：

myname@My-Laptop:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb        251G  239G     0 100% /

我怎样才能清理一些空间（不删除重要文件）以便再次打开 jupyter 笔记本？

答案1

问题不在于您的机器上是否有空间，而在于您尝试写入的特定位置是否有空间。在这种情况下，您的df输出非常清楚：您的根分区已 100% 满。这就是第一行告诉您的内容：

myname@My-Laptop:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb        251G  239G     0 100% /

并且错误会准确地告诉您 Jupyter Notebook 试图写入的位置：

[E 07:58:41.192 NotebookApp] Failed to write server-info to /home/aswirbul/.local/share/jupyter/runtime/nbserver-71.json: [Errno 28] No space left on device

该文件/home/aswirbul/.local/share/jupyter/runtime/nbserver-71.json位于/home/aswirbul/.local/share/jupyter/runtime/的子目录中/，并且该分区上没有剩余空间。由于您尝试写入，因此输出/中的其他行均不df相关。是的，您的 Windows 驱动器上有空间，但这不是您要写入的位置，因此它没有帮助。

您需要删除一些文件。我们无法告诉您删除了哪些文件，因为我们无法访问您的计算机，也不知道哪些文件是“重要”文件，但 251G 是很多Linux 系统的空间有限，所以你可能有各种各样的东西闲置着。看看这里的解决方案：没有更多磁盘空间：如何找到占用空间的内容？

当您尝试将太多文件写入目录时，您可能会收到此错误，请参阅我的回答：https://stackoverflow.com/questions/6998083/python-causing-ioerror-errno-28-no-space-left-on-device-results-32766-h/78195484#78195484即使您的文件系统有足够的空间来表示所使用的文件名，也会有最大目录大小限制。
