Hello,
I tried to upgrade my Elasticsearch cluster (4 nodes) from 6.3 to 6.8 and I failed. In my actual cluster (6.3), I don't have the security enable, in version 6.8 the security is free so I want to enable it. This is my Elasticsearch cluster topology :
- Node 1 : data/master node
- Node 2 : data/master node
- Node 3 : data/master node
- Node 4 : coordinating only node
This is my upgrade process ([based on Elastic documentation](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/restart-upgrade.html)) :
1. **Disable shard allocation**
2. **Stop indexing and perform a synced flush**
3. **Shutdown all nodes**
4. **Start each upgraded node**
5. **Execute "elasticsearch-setup-passwords" commands to set the passwords for the built-in-users**
But, during the step 5 (elasticsearch-setup-passwords) I obtain this following error :
> Initiating the setup of passwords for reserved users elastic,apm\_system,kibana,logstash\_system,beats\_system,remote\_monitoring\_user.
> You will be prompted to enter passwords as the process progresses.
> Please confirm that you would like to continue [y/N]y
> Enter password for [elastic]:
> Reenter password for [elastic]:
> ...
> Reenter password for [remote\_monitoring\_user]:
>
> **Connection failure to: [https://127.0.0.1:9200/\_xpack/security/user/apm\_system/\_password?pretty](https://127.0.0.1:9200/_xpack/security/user/apm_system/_password?pretty) failed: Read timed out**
>
> **ERROR: Failed to set password for user [apm\_system].**
And, in my Elasticsearch node logs, I noticed this error :
> 2019-07-19T12:00:24,051][WARN][r.suppressed] [elastic\_node\_1] path: /\_xpack/security/user/apm\_system/\_password, params: {pretty=, username=apm\_system}
> org.elasticsearch.action.UnavailableShardsException: [.security-6][0] [1] shardIt, [0] active : Timeout waiting for [1m], request: indices:data/write/update
I believe understand the error, maybe because I have disable shard allocation on my cluster and my cluster has yellow state. Why can I fix this problem?
Thank you in advance for your help.
