Upgrade to 6.5 - snapshot error: Gateway Time-out

[humalog]

Hi guys,

i would like to upgrade Elasticsearch (6.4), Kibana (6.4) and Logstash (6.4) to version 6.5.

I found 2 links how to do the upgrade (it's my first upgrade at all), Rolling upgrades and Elastic Stack 6.3 Upgrade Guide. I decided to use the Elastic Stack 6.3 Upgrade Guide.

I am at point 1, back up your data. I added path.repo to my elasticsearch.yml, all works. Now when i want to make my first snapshot i get following error:

Snapshot:

PUT /_snapshot/my_fs_backup/%3Csnapshot-%7Bnow%2Fd%7D%3E?wait_for_completion=true

Error:

{
  "statusCode": 504,
  "error": "Gateway Time-out",
  "message": "Client request timeout"
}

I read smth. about Load Balancer in front of ES cluster, but i have no idea how to handle this.

My question is now, should i change my upgrade to Rolling upgrades and don't make a snapshot or is there an easy way to solve this error?

Best regards

My bad,

when i started the snapshot, my device run out of space. I will try to update with Rolling upgrades topic.
