So I'm getting a root partition as full after some errors. Here is what I'm seeing.

    Filesystem      Size  Used Avail Use% Mounted on
    /dev/sdb1       175G  175G     0 100% /
    none            4.0K     0  4.0K   0% /sys/fs/cgroup
    udev            7.8G  4.0K  7.8G   1% /dev
    tmpfs           1.6G  1.4M  1.6G   1% /run
    none            5.0M     0  5.0M   0% /run/lock
    none            7.9G     0  7.9G   0% /run/shm
    none            100M     0  100M   0% /run/user
    overflow        1.0M     0  1.0M   0% /tmp

As you can see here. I kind of know what happened. I migrated my server to new hardware. My backup USB drive changed UUIDs. I was tired and put the wrong one. So the root drive mounted to / and /backups. When the RSYNC job ran to backup I'm sure it was one hell of a loop. I get what happened but what I can't figure out for the life of me is how to recover these files. I've since taken that part out of my /etc/fstab file. Then removed the backups directory. I've ran all kinds of things like NCDU, df -h, etc and I cannot find where these "double" files would've be. It's the only thing I can think of that may have caused this. Again I can't find these double files anywhere but my disk is showing as full so they must be somewhere....Any help or tips are appreciated.


should have shown you where the problem was.

Have you tried booting from a live usb like sysrescuecd or grml, so the system is offline, then mounting the root partition and checking with ncdu.


You could dump your whole file tree to a file, then have a look in a text editor, or even a spreadsheet at 10% zoom, to see where parts might appear to duplicated or recursive.
