***NEVER*** delete large files on an impacted filesystem, *unless* you
first zero them out, *and* insure nothing's accessing them:
$ cat /dev/null > bigfile # truncate bigfile
$ fuser bigfile # who's using bigfile?
# If and only if no processes have file open:
$ rm bigfile
...by deleting a file, you lose access to it, and are now no longer able
to (easily) truncate it, move it, rename it, or find out who's using it.
While a skilled GNU/Linux user should still be able to recover, you may
find it's easier to boot your system to close the open file.

List open files:
$ lsof /
You can also see what directories are using the most space. You want to
list directories which are part of your root filesystem, *not* those
which are separate filesystems. In my case:
$ du -sx /bin /dev /etc /initrd /lib /lost+found /root /sbin |
sort -nr | cat -n
...the latter being for readier viewing. You can then descend through
the larger directory(ies) with:
$ du -sx * .[A-Za-z0-9_]*
...which should pick up most normal and 'dot' files.
Cheers.
