Openhab does not run anymore because of missing space on device.
df -h shows that /dev/root is 100% in use and i dont know why. Also i cant find out, what exactly grew this much.
It runs on Raspberry with openhabian, Openhab 3.5.
any idea?
Something has written to disk until it got full. Are you sure it’s /dev/root? I have a recent openHABian and there is no such file system.

Notice that the root of the file system appears in the last column. That might give a clue.
The following command will give the top five directories by size in <path>.
du -a <path> | sort -n -r | head -n 5
Replace <path> with the value under “mounted on” in the game returned by df that corresponds to the full file system.
