ubuntu "No space left on device" but there is tons of space [closed]
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!
but when i do df -h i get:
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

/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:
ubuntu@ip-10-0-2-108:~$ df -i

I am on an Amazon EC2 ubuntu 12.04 instance.
Here are some examples of the error popping up:
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??
Solution 1:
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.
Try unmounting the overflow partition:
umount /tmp
or
umount overflow
