Also one more question - lets say intially I have one node architecture - i.e. everything on one single node and additional mount is having all the ES data (index, documents etc) which is like of 300 gigs - now lets say if I add more data nodes - so going forward it will distribute the shards to different nodes or existing data will automatically be redistributed too?
