Elasticsearch – Best practices to reboot Database on Linux

Hi Dojo,

Are there any requirements or recommendations to do a Elasticsearch Database rebooting? I have some recommendations about Cassandra but I have no information about Elastic.

Note that we’re running Elastic on Linux OS.

Hi Daniel,

It’s best to disable shard allocation before doing any reboots

(it’s going to mangle the json I’m going to put below)

Send the following to http://<cluster node>:9200/_cluster/settings

{
  “transient” : {
    “cluster.routing.allocation.enable”: “none”,
    “cluster.routing.rebalance.enable” : “none”
  }
}

You can then reboot each node in turn as required.

Replace
“none” with null (note no quotes on null)
to renable

Once your nodes have all been restarted, send a retry shard allocation HTTP POST request
http://<cluster node>:9200/_cluster/reroute?retry_failed=true

You’ll see after a few minutes any indicies with yellow status turn green

Hope that helps
Chris
