The user with full access to the system via SSH is 'root' (no quotes) not admin.

You could do a bind mount of the mounted root volume to look for what's taking up the space

# mount --bind / /mnt
# du -csh /mnt/*

Once you've found what's filling it you can identify why, deal with the situation and when you're done don't forget to do

# umount /mnt

Thanks that did help but now when i try to unmount i get this

root@ZombieNAS:/mnt# unmount /mnt
-bash: unmount: command not found

That's an easy mistake to make (speaking from experience).
