Have a last question - from this post Is it possible to split an existent ReplicaSet? - #8 by Prasad_Saya
I followed all the instructions as described there. A new master of a new replica set started successfully. However, when I try to add another machine to the new replica set, which I previously removed from the other replica set (and, of course, I deleted the “local” database), the rs.add() command on the new master hangs, and nothing happens. I use ctrl+c to interrupt it, but rs.status() shows that the machine with the replica is in the “startup” state, but there is nothing on the replica itself.
