问题描述
当文件完成上传时，服务器会报告：
I'm uploading a small file (8.5 Mb) to a flask test server.
When the file finishes uploading, the server reports:已经查看了以尝试查找位置Werkzeug试图写信，但不能追查。

我也检查了，它将/ var / tmp作为临时文件目录，但是这个文件夹实际上是空的，所以我不认为这是造成问题的位置。
Now, the server has plenty of free space - over 3Gb.
如何找到没有空间的设备？
This unix SE answer explains what happened.
我卸载/ tmp目录并遵循Nitesh的建议：
I unmounted /tmp directory and followed Nitesh's suggestion:
sudo umount /tmp
sudo echo 'MINTMPKB=0' > sudo /etc/default/mountoverflowtmp
现在上传正常。
这篇关于IOError：设备上没有剩余空间 - 哪个设备？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
