System volume 'root' usage is 100%

I've got a client with a Readynas 102, I just started getting this error message in my email today, every ten minutes: System volume 'root' usage is 100 %. This condition should not occur in normal...

I think I found the problem. For some reason the 'Transmission' add-on installed the download folder in the root directory, filling up the root dir rapidly. Although in the config.json file, the download directory is /Data/Transmission/Incomplete

Weird...

    So I'm running into this. Right now I am getting emails every 10 minutes saying root is at 100%.

     

    However, df shows everything is fine. Rebooting didn't appear to help...

     

    Is there some hidden space or something??

      Did you also check inodes?  df -i

        Yea, df -i looks fine:

        root@Storage:/var# df -i

tmpfs          504422     1 504421    1% /data/home/Scott/snapshot

        So,  I did have a couple of things in /var/lib which were taking up space (squeezeboxserver, and mysql). I was able to relocate those to /apps.

         

        But now I am here (which is better):

        root@Storage:/# df -h .
        Filesystem Size Used Avail Use% Mounted on
        /dev/md0 4.0G 2.8G 898M 77% /

        and I can't figure out what is taking the space...

        root@Storage:/# du -sh /var
305M    /var

        Any other places I should look?
