Looks very similar to a problem I had.  The node_up script would
crash, leaving the node in the "unavailable" state and the romfs
mounted as root. So of course you can't copy anything over.  The
solution is to fix the "extra free" bug in bpcp that cause it, and
thus node_up, to crash.  Obtain the source from the bproc srpm,
and then change clients/bpcp.c line 314 (I believe) to say
something like /* free(bp); */

Hope this helps.
