Of course, but for the user it might be better to skip handling of this 
error and to continue with the next vnode. So he could get back at least 
the damaged volume and copy whatever is still accessible.

So John, ifdef line 3175 and recompile. If this was a single bad vnode 
your volume may come online again, otherwise it's probably lost anyway.
