The clients refresh their knowledge of volume location every two hours.
This can be forced with "fs checkvol".   The UUID represents the file
server, not the interface.  Once a client determines that an interface
is down it will stop using it.

If the file server supported changing its address list while running
the answer would be in two hours.  However, the file server does require
a restart in order to register a new address list.

fs checkvol will instruct the clients to ask the vldb for the new
locations of all volumes.
