r=2152

replay-single.sh now supports multiple nodes. The script must be run
on the client, but the mds, mdsfailover, and ost can all be different
nodes. If mdsfailover_HOST is set, then the MDS service  will be
failed between the two mds nodes.

uml1# PDSH="pdsh -w" mds_HOST=uml2 ost_HOST=uml3 mdsfailover_HOST=uml4
  ./replay-single.sh

It still runs on a single node as before.
