I was looking over the src logic for doing a restore with overwrite
mode off because the docs left me unsure if restores that we currently
consider routine and undestructive could be done without specifying
overwrite mode.
Everything looked fine, except that I'm still not sure what happens in
one particular case. The setup is as follows:
Volume user.foo is requested to be restored to server volley,
partition a with overwrite mode off. A vldb entry for user.foo exists
and states that user.foo is on server mate partition f.
Does the slave check to see if the volume exists on server volley or
server mate before okaying the restore?
It looks like the code checks the volley server. It should check mate
because that's where an active user.foo volume is most likely to be.
If we wanted to be extra paranoid also checking volley would be good,
but I don't think it's absolutely necessary.
