If I make cluster with different disk space nodes for example 3 nodes one with 1TB and two with 512GB. and I did shards 3 and replica 1. How elasticsearch will distribute shards and replica on these different size nodes? What is 512GB nodes are full. How elasticsearch work in this case? Regards ---

It'll try to balance everything based on shard count, but if disk space gets too low then the watermarks will likely be hit, see [https://www.elastic.co/guide/en/elasticsearch/reference/6.1/disk-allocator.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/disk-allocator.html) ---
