How to modify the ES configuration and reboot ES cluster properly?

(Keith Tt) #1

ELK version: 5.5.1

Restart nodes one by one is terrible......

Should I refer to this guide?

That is the correct method.

Also we’ve renamed ELK to the Elastic Stack, otherwise Beats feels left out :wink:

So...If there are 10 nodes in the cluster, it possibly needs one day to restart all the nodes.

When one node is restarted, should I wait all the shards been allocated and the cluster's status recover to green? This progress spend much time...

If you are on version 5, then delayed allocation and synced shards should negate any delays.
If they aren't, then it'd be great to know more information.

Even if I disable shard allocation and perform a synced flush before I restart each node, it still spends much time to recover after I reenable shard allocation...
