i have 8 data node elk and metricbeat configured with shard 2 replica 1. most of the times all of the shard is maximum spread in 3 node . in order to max performance i trying to create index with 5 shard replica 1 and doing a reindex . but i see all primary , replica created in just 3 nodes instead of using all nodes . 1st node has 4 shard , 2nd node 5 and 3rd node 1. question is how can i ensure all my primary to be in different node so that my performance is better? out of 8 nodes 4 nodes have disk size 50% of remaining nodes . i.e 4 nodes have 1.5 tb and others have 3tb . is there problem on performance and unequal allocation ---

What is the shard count per node? Do you have shards of very different sizes? How large is the largest shard? ---

we have 15 metric indexes each 550-600gb with 2 shards 1 replica and 6 rollup indexes less than 110gb same shard/replica set up ---
