Thanks for your reply, kurt.
another question, Can I bootstrap a new node when some node is in Joining state ? Or I should wait until Joining node becoming Normal ?

It's not straightforward and will likely lead to data loss/inconsistencies. This applies for all current versions.

So I wonder to know Is it ok to add more than one node to a exist cluster in 3.0.10. Thanks! Dayu
