I am in the process of setting up a private, permissioned Quorum blockchain with Istanbul consensus for simple use cases. When I specify the number of validators when generating the genesis file it works as expected.

But how can I add validators dynamically? For example I have generated genesis file with two validators and it is up and running. Now if I want to add a new node as validator how I should configure? If I use the same genesis file and added new node's enode address to permissioned-list it is connecting successfully but getting unsealed signature error. Do I need to modify the genesis file extraHash field for new nodes?
