How to fix this problem?
If I use
df -i
I receive:
Filesystem Inodes IUsed IFree IUse% Mounted on
udev 218483 402 218081 1% /dev
tmpfs 220126 340 219786 1% /run
/dev/disk/by-label/DOROOT 2621440 2621440 0 100% /
none 220126 1 220125 1% /sys/fs/cgroup
none 220126 1 220125 1% /run/lock
none 220126 1 220125 1% /run/shm
none 220126 1 220125 1% /run/user
If I use
df -h
Seems to be good
Filesystem Size Used Avail Use% Mounted on
udev 1005M 4.0K 1005M 1% /dev
tmpfs 202M 340K 202M 1% /run

none 4.0K 0 4.0K 0% /sys/fs/cgroup

none 1008M 0 1008M 0% /run/shm

How to solve “IUse - 100%” ? Thank you!

df -i checks for inode usage. Inodes only represent sort of structures or objects which are written on your device, basically a metadata or pointers. Being full on Inodes usually means that you have too many files (in terms of amount, not size) written on your disk.
Perhaps you’re using some application which writes too many small log files or stores the sessions data for each visitor and doesn’t clean-up.
More on this issue and how to solve it/find the files can be found here - http://unix.stackexchange.com/questions/117093/find-where-inodes-are-being-used
Occasionally, a file will be deleted, but a process is still using it. Linux won’t release the storage associated with the file while the process is still running. You just need to find the process and restart it.
Try to locate the process.
The problematic process should be listed, then just restart it.
If this doesn’t help, then I’ll recommend trying to reboot the droplet and see what happens.
