So, basically the recommended approach is to run "find" every time a server
goes down or comes up?
How then one insures files are re-balanced on remaining servers? I mean, AFR
would just look for the next free server and it put them there?
And after the problematic server comes up again, AFR would erase the
redundant file copies from it?
