Here are my df -h and df -i.
df -h
Filesystem Size Used Avail Use% Mounted on /dev/vda1 40G 40G 0 100% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 991M 4.0K 991M 1% /dev tmpfs 201M 344K 200M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1001M 0 1001M 0% /run/shm none 100M 0 100M 0% /run/user
df -i

The

Think of it as an elevator which can accommodate 9 people and has a weight limit of 1000KG. Four people get in with very heavy luggage all of them totaling close to 1000KG. Now even if there is room for more people the elevator cannot work.
So if one single file took up lots of space (like 30G) you’d still have free inodes while the disk is full.
Use the following command to find out which directory is taking up a lot of space.
This command could take a long time. After it completes drill down to the largest directory .
Example:
Keep executing the
ducommand till you find the directory that houses the large files.
