The way hardlinks work is that the space for the data is not
released until the last link is removed, and all of the
files have a link under the cpool directory.  The manual
approach to that is to cd into the cpool directory and
find . -type f -links 1 |xargs rm
That is, remove the files in the pool that no longer have any
links from pc backup directories, but you can do some
damage if you get this wrong.
