The files appeared removed from the filesystem but the results of a `df -h /var/lib/mysql` showed that no disk space has been cleared. A `du -sh /var/lib/mysql` on the other hand says that ~ 30GB was removed.

  I think this could be caused by a problem I've described in:
http://www.mail-archive.com/ocfs2-devel@oss.oracle.com/msg02886.html

  The question is what is the right fix for this race. I describe one
possibility in
http://www.mail-archive.com/ocfs2-devel@oss.oracle.com/msg02938.html
but I got no response so far and honestly it is a bit hacky solution.
  I can write the fix if people here agree that that's the way to go.
