Hello,
I have one node on 24 receiving zero shards, and I can't figure out why.
Nothing in the logs, cluster is green, node accepts requests.
any Idea on how to identify the problem?

Are all nodes on exactly the same version? How come it lists `1.8tb` as used disk space?

Well done, all nodes are 2.3.4 except the problematic node which is 2.3.0.
the disk used space contains elasticsearch and other log datas
I will upgrade this node and check if it solves my problem 😉
thank you
