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

Setting auto_bootstrap on seed nodes is unnecessary and irrelevant. If the
node is a seed it will ignore auto_bootstrap and it *will not* bootstrap.

"it seems that we still need to keep bootstrap false?"
Could you shed some light on what would happen if the auto_bootstrap is
removed (or set to true as the default value) in the seed nodes of the
newly added DC?
What do you have in the seeds param of the new DC nodes (cassandra.yaml)?
Do you reference the old DC seed nodes there as well?

Re: auto_bootstrap for seed node
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.

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
