STATUS QUO:
I have found a filesize check here
which explains a bit more than I will explain here. Be aware that the syntax over there has changed a bit since at least regarding folder / file depth which is not “-d 1”.
du -h -d 1 /
Result is this, which I have manually formatted and resorted to make it more readable
1400M /
569M /media
483M /var
313M /usr
44M /config
13M /package
11M /root
7M /lib
3M /bin
2M /etc
1M /sbin
1M /run
76K /tmp
60K /data
52K /command
12K /home
4K /opt
4K /mnt
4K /srv
4K /ssl
4K /addons
4K /share
4K /backup
4K /lib64
0 /sys
0 /proc
0 /dev
Strange thing: if you add it up you will have a sum of just 2.847 MB but I have a 8 GB SD card and still just 0,6 GB free and I am not able to run a backup.
Yes, i have restarted the system 2 times fully.
What is wrong ?
And what about 1,4 GB of files in the root directory I can not see?
