So you are replacing the OSS_MASTER2 machine with a new machine and
assigning it the same IP address as OSS_MASTER2?  (i.e. why don't you

machine?

Well, if you duplicate the IP address faithfully, it should work.  Can
you supply the output of dmesg after you have mounted the client and
done a "df -h" on it?
