Replica diversion policy
Node n rejects replica f when Sf / Fn > t
- Sf : size of f
- Fn : remaining free space in node n
- t = tpri = .1 for k closest nodes
- t = tdiv = .05 for other nodes
If one of k closest nodes rejects, replica is diverted to least utilized node in leaf set
If that node rejects, then file is diverted
