Cluster Routing Allocation Settings

Elastic Stack Elasticsearch
1

We have a cluster of two nodes (ES 2.2), indexes have one replica so all shards are in both nodes. If we restart a node, all shards in that node are set as unasigned, we think this can be resolved with

"transient": {
"cluster": {
"routing": {
"allocation": {
"enable": "none"

but we don't understand the meaning of another parameter disable_allocation": "false"? is from another version?

how can then reset transient settings?

thanks

It won't prevent that, you will still have half of your shards unassigned.

It's the same thing, just an older variant/

That's difficult until 5.X, so you should upgrade.

Thansk for the response, can we prevent " all shards in that node are set as unasigned" in another way?
so we have no shards unassigned, or at least a big % of them?

Don't shut down the node, or add more nodes.
