When the network topology changes you need to partition the network again to reflect the change.
You might need to re-generate the partition blobs when you partition the network.
Hope it helps!
Thanks for the reply. I tested it and indeed it needs to be re-partitioned. The only problem is if I am to add just a few data, I will need to re-partition the whole network and it takes hours to complete since I have a large network. That means the system will be unusable during the partitioning of the network.
