[Pvfs2-developers] Trove DBPF error

[David Metheny]

I haven't verified with pvfs2-rm that it cleans up all the pieces that it
can get to for the file (i.e. all the valid bstreams), but pvfs2-rm does get
rid of the file so that it quits complaining.

Can we make a "-f" option do what we want with pvfs2-rm?
