ubuntu "No space left on device" but there is tons of space
提问by Or Gal
I am getting the "No space left on device" error for pretty much anything i try to do. Even using tab to autocomplete a command!
对于我尝试做的几乎任何事情，我都收到“设备上没有剩余空间”错误。甚至使用 tab 来自动完成命令！
but when i do df -h i get:
但是当我执行 df -hi 时得到：
ubuntu@ip-10-0-2-108:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 99G 6.5G 88G 7% /
udev 3.7G 8.0K 3.7G 1% /dev
tmpfs 1.5G 184K 1.5G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 3.7G 0 3.7G 0% /run/shm
none 100M 0 100M 0% /run/user
/dev/xvdb 414G 199M 393G 1% /mnt
overflow 1.0M 1.0M 0 100% /tmp
which to me looks like there is tons of space. df -i also looks similar:
对我来说，这看起来有很多空间。df -i 看起来也很相似：
ubuntu@ip-10-0-2-108:~$ df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/xvda1 6553600 94227 6459373 2% /
udev 951353 393 950960 1% /dev
tmpfs 953649 274 953375 1% /run
none 953649 3 953646 1% /run/lock
none 953649 1 953648 1% /run/shm
none 953649 1 953648 1% /run/user
/dev/xvdb 27525120 11 27525109 1% /mnt
overflow 953649 12 953637 1% /tmp
I am on an Amazon EC2 ubuntu 12.04 instance.
我在 Amazon EC2 ubuntu 12.04 实例上。
Here are some examples of the error popping up:
以下是一些弹出错误的示例：
ubuntu@ip-10-0-2-108:~$ sudo crontab -e
/tmp/crontab.RvYjrR/crontab: No space left on device
ubuntu@ip-10-0-2-108:~$ ls /va (hit tab for autocomplete)
-bash: cannot create temp file for here-document: No space left on device
-bash: cannot create temp file for here-document: No space left on device
however the server seems to be running and everything seems to be working. what on earth is going on??
但是服务器似乎正在运行，并且一切似乎都在运行。这到底是怎么回事？？

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.
您可能已经用完了内存或其他地方的一些空间，它提示系统挂载溢出的文件系统，无论出于何种原因，它都不会消失。
Try unmounting the overflow partition:
尝试卸载溢出分区：
umount /tmp
or
或者
umount overflow
