This is not so good: only 6 megs of free disk space.

11 megs here isn't so hot either

space is a little tight here, too


So we need to focus on those three first.  nightcrawler is the reason
you only have 5*8=40 MB free, but the other two aren't helping much
either:  Are those three the original servers?  Do they have a log
file or anything else consuming space in the pvfs2 storage-space
that's not part of PVFS2?  

Do we have a good way to reverse-map data files on disk to pvfs2
files?  If so, you could find what the largest datafiles on
nightcrawler, rouge, and wolverine were, and then free up some space
by moving them somehwere temporarily.  

I think we can figure this out.  Just might take a few rounds.
