We followed this 
https://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html,
but it does not mention that change bootstrap for seed nodes after the rebuild.


Thanks,

You might want to follow DataStax docs on this one: 
 
For adding a DC to an existing cluster: 
https://docs.datastax.com/en/dse/5.1/dse-admin/datastax_enterprise/operations/opsAddDCToCluster.html
 
For adding a new node to an existing cluster: 
https://docs.datastax.com/en/dse/5.1/dse-admin/datastax_enterprise/operations/opsAddNodeToCluster.html
 
 
briefly speaking, 
adding one node to an existing cluster --> use auto_bootstrap 
adding a DC to an existing cluster --> rebuild 
 
You need to check the version of c* that you're running, and make sure you pick 
the right doc version for that. 
 
Most of my colleagues miss very important steps while adding/removing 
nodes/cluster, but if they stick to the docs, they always get it done right. 
 
Hope this helps

 auto_bootstrap for seed node
 
    
 

 
 
 
Dear All, 
 
For adding a new DC ,we need to set auto_bootstrap: false and then run the 
rebuild,finally we need to change auto_bootstrap: true,but for seed nodes,it 
seems that we still need to keep bootstrap false? 
Could anyone please confirm? 
 
Thanks, 
Peng Xiao
