There is the vos convertROtoRW command, if you are sure that the down 
server will not come back up (and you are using the NAMEI version of the 
fileserver.)  You can also just start restoring your dumps, either to 
the other servers (if you have enough diskspace) or to a newly installed 
server on the same IP as the downed one.

In fact, you can even bring up a new fileserver only machine on a 
completely new IP and restore things there, if you intend to reinstall 
the downed one and move files back to it.
