No more space available even if there is a lot

I am experiencing some weird issue lately. I am using this machine as a web server. When I try to write a file in a directory it says there is no more space. I deleted some files and it worked for a little while. After few minutes I get the problem again:

root@web1:/home# mkdir test
mkdir: cannot create directory ‘test’: No space left on device
root@web1:/home# df -h
Filesystem             Size  Used Avail Use% Mounted on
/dev/mapper/web1-root   43G  4.5G   37G  11% /
none                   4.0K     0  4.0K   0% /sys/fs/cgroup
udev                   3.9G  4.0K  3.9G   1% /dev
tmpfs                  798M  828K  798M   1% /run
none                   5.0M     0  5.0M   0% /run/lock
none                   3.9G     0  3.9G   0% /run/shm
none                   100M     0  100M   0% /run/user
/dev/sda1              228M   91M  126M  42% /boot
/dev/sdb1              197G   75G  113G  40% /home

df -i reports a partition with 100% usage:

root@web1:/home# df -i | grep 100%
/dev/sdb1 13107200 13107200 0 100% /home

Solution 1:

Like @Rinzwind and @heemayl suugested i ran out of inodes searching on google i foudn the answer ... http://www.ivankuznetsov.com/2010/02/no-space-left-on-device-running-out-of-inodes.html

this is the solution

check available Inodes

$ df -i

find which directory is having more inodes

$ for i in /*; do echo $i; find $i |wc -l; done

recursivly repeat the search until you find the problem

$ for i in /DIRWITHHIGHINODES/*; do echo $i; find $i |wc -l; done

once you found the suspect – just delete the files

$ sudo rm -rf /home/bad_user/directory_with_lots_of_empty_files

You’re done. Check the results with df -i command again. You should see something like this:

Solution 2:

I see the output shows high inode usage this seems to be the best answer thread out there. It is very extensive.
