Problem with unassigned Shards

Elastic Stack Elasticsearch
1

Hello,

I came to work from my holidays today and have some troubles with my shards.
> {
> "cluster_name" : "elasticsearch",

Any ideas on how to fix that?

You really need to reduce that shard count, it's way too high!

However check your master logs for why.

Have a look at the pending tasks and your logs.

That being said you have a way too much shards per node IMO.

I found the problem my diskspace-watermark was too low.

How can I reduce it? I can't change the number shards once they are configured, if I remember it correct.

If you are on 5+ you can use _shrink.
