Add a new node

Hi

I wanted to add additional new node in different data center to existing
node (single) by changing shards to 4/5. Does this need an index rebuild ?

Any other setting/hints for cross data center (other than discovery, as we
use unicast + IP).

Thanks

David

Yes, you need to rebuild your index if you have to change the number of
shards. You can change the number of replicas on the fly, though.

Any other setting/hints for cross data center (other than discovery, as we
use unicast + IP).

I assume you don't want your shards to move around from one datacenter to
the other. If that's so, have a look at shard allocation settings:
