Linux – AWS EC2 – No Space Left on Device

amazon-web-serviceslinux

I have an EC2 instance and when I log in I get 

mktemp: failed to create file via template '/tmp/.colorlsXXX': No space left on device

However when I do df -h I see

Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      7.8G  4.2G  3.5G  55% /
devtmpfs        812M   16K  812M   1% /dev
tmpfs           828M     0  828M   0% /dev/shm

Doing df -i gives me

/dev/xvda1     524288 524288      0  100% /
devtmpfs       207790    414 207376    1% /dev
tmpfs          211891      1 211890    1% /dev/shm

What's going on here?

You have exhausted all of the inodes available on your filesystem. You likely have a directory somewhere with a metric crap-ton of tiny files. You'll need to locate that directory and remove some of the files.

To search which folder of your server is eating the inode limit, you can run this command:

find . -xdev -type f | cut -d "/" -f 2 | sort | uniq -c | sort -nr
