Please note that you have to have free data blocks AND free inodes in the
directory tree.

I had an ext partition that ran out of inodes in the directory tree, and
couldn't write to the mounted partition, even though it was only about 20%
full at the time (lots of small files)

Also, many file systems reserve some small amount for root use only (about
1 to 5%) so your drive may look like this:

Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda8             27886048  27328327    557721  98%   /mnt/28g

And still report being out of room.
