Hello Elastic

We have a cluster of 30 machines and each index has 1 replica. So we can tolerate 1 VM taken down. But we have to repair 2 VMs now. We have a day ahead of us. Is there a way to move all shards from the 2 VMs to the rest of the cluster? Any command?

I think [https://www.elastic.co/guide/en/elasticsearch/reference/6.2/allocation-filtering.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/allocation-filtering.html) could be what you are looking for.

if i exclude two machines? will the cluster go red?

i.e. { "transient" : { "cluster.routing.allocation.exclude.\_ip" : "ip1,ip2" } }

It'll start to move shards off those two nodes, but it shouldn't go red.
