I am in the process of validating using nodes with multiple disks. I need an easy way to have a high level idea where the shards are located.
I typically use "GET /_cat/allocation?v" to show the overall disk usage.
Then use "GET _cat/indices?v" & "GET _cat/shards?v" to drill down if need to.
Is there another simple call to show which datapath a shard is located within a node?
