Issues changing /_cluster/settings in OpenSearch cluster hosted on AWS

Hello,

I was wondering if anyone knew a workaround for changing the /_cluster/settings in an OpenSearch cluster hosted on AWS.

What I would like to do is adjust the following settings on my OpenSearch cluster:

“cluster.routing.allocation.disk.watermark.flood_stage”
“cluster.routing.allocation.disk.watermark.high”
“cluster.routing.allocation.disk.watermark.low”

However, it seems AWS does not allow these to be changed, at least not via an http PUT request.

This error is returned when trying to make changes to these settings:
{“Message”:“Your request: ‘/_cluster/settings’ payload is not allowed.”}

Does anyone know a way to get around this? Thanks so much for your help.

hello @taeyoungk21 - welcome to the community. I’ve not been able to find how you would change these settings on the managed service either. I’ll ask around and see if anyone has ideas.
