When you specify a seed in a node's configuration it's just a way to let it know how to find the other nodes in the cluster. A node functions the same whether it is another node's seed or not. In other words, all of the nodes in a cluster are functionally identical - no masters, no slaves, no seeds, etc. So, when adding a new node to an existing cluster, you should AutoBootstrap= it.

And if s= o, will a seed node newly added to an existing cluster then not take long t= ime before it actually starts getting any work to it? I mean, if it doesn't= start with moving some data to itself, it will have to wait until new data= comes in and is determined to live on that new node. > Correct? > > /Per > >
