Well, yes it stops replicating when the mindevcount is reached, but when
some servers are dead the replicator will try to replicate to maintain the
number of replica not to lower than the mindevcount, and when those
servers are back, the devcount of some files might equal to the
mindevcount + the number of dead servers ?

I'm testing on 4 servers, some files have devcount=4 while their
midevcount is only 2, when all servers are alive there are 4 replica on my
system. So, I'm a little worried if MofileFS doesn't do some cleanup.
