We want to implement the shrink index API on our cluster. A pre-requisite is that all shards in the to-be-shrunk index must reside on the same node. Currently, this is not the case.

What is the simplest way to move all shards in an index to the same node?

Thanks!

Welcome to our community! 😃

[Index-level shard allocation filtering | Elasticsearch Guide [8.7] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.7/shard-allocation-filtering.html) and use `index.routing.allocation.require.ip` and then add in the IP of the host (or use `hostname`).

However if you issue a shrink request, Elasticsearch should handle the re-allocation for you.

In the v7.17 docs. the shards all residing on the same node is stated as as a prerequisite, not something that "Elasticsearch will handle for you". I am about to create a task to create this prerequisite. Should I not do so?

Thanks.
