Rolling upgrade sequence of node types

Elastic Stack Elasticsearch
1

Hi, rolling upgrading from 6.1.2 to 6.2 which includes node types: master ingest, coordinator and data and I use free license for monitoring.

I encoutered 2 issues..

1- I had started with the master nodes...
Elastic complained that it could not create the .watcher index. So I reverted and and had to add extra flag to allow me to delete the watcher index...

2- After I reverted the master nodes I tried doing the data nodes first. But the data nodes complained the master nodes where NOT 6.2 and would NOT join the cluster.

Extra note: Had skipped disabling shard allocation.

Extra question: Because its a containerized enviroment. Mesos with Docker and resource contraints. I need to wipe the data node and its data volume completely so the new container can use the resources on that host. Is that ok?

2

Can you share relevant logs from these things?

Ok I'll get back...

Hi, @warkolm

Trying to upgrade again started with the master nodes...

Going from 6.1.2 to 6.2.2. I have the basic x-pack license.

I got 5 of the below message...

Is that ok?

Every time I do an action I get that message... So for example here I remove a master node and then the exceptio and then the x-pack message again.

All nodes needs to have x-pack installed. You can't do that with a rolling restart unfortunately.

I'm pretty sure I do.... Using the basic license. Is there a way to check if all nodes have it?

I'm installing using docker

FROM docker.elastic.co/elasticsearch/elasticsearch-platinum:6.2.2

And logs from one node:

I think that when you do rolling upgrade, all the masters have to switch to 6.2.2 and turn off the 6.1.2??? Once I did that the error stopped...

Yeah, that did the trick! I'm updated!
