This sounds like node 3 is a primary node of a replicate set. If you shoot down your nodes 1 and 3 you will notice this problem. If you shoot down node 2 and 4 you will see the files being healed. BUT you should nevertheless be able to heal the data by only stat'ing the missing files on the clients - even if you cannot see them first, they should reappear after stat. -- Regards, Stephan
