S.O: Ubuntu 18.04 ES: 7.6.1 (Before upgrade) I tried to upgrade my ElasticStack with 3 nodes (1 master, 2 slave). Following the [Guide](https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html). And all of those steps are only on master. here my steps: ```auto curl -XPUT -u elastic:changeme "localhost:9200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d' { "persistent": { "cluster.routing.allocation.enable": "primaries" } } ' ``` ```auto curl -XPOST -u elastic:changeme "localhost:9200/_flush/synced?pretty" ``` ```auto service elasticsearch stop ``` ```auto apt-get update && apt-get install elasticsearch ``` Eventually this asked for override my `elasticsearch.yml` file, I pressed "N". And then tried to start elastic but got error: ```auto [2021-06-16T13:06:56,069][INFO][o.e.i.g.DatabaseRegistry] [master] initialized database registry, using geoip-databases directory [/tmp/elasticsearch-1576930118492589462/geoip-databases/V3a78v1XTUWzHmDr52dZBA] [2021-06-16T13:06:57,054][INFO][o.e.t.NettyAllocator] [master] creating NettyAllocator with the following configs: [name=unpooled, suggested_max_allocation_size=1mb, factors={es.unsafe.use_unpooled_allocator=null, g1gc_enabled=true, g1gc_region_size=4mb, heap_size=1gb}] [2021-06-16T13:06:57,168][INFO][o.e.d.DiscoveryModule] [master] using discovery type [zen] and seed hosts providers [settings] [2021-06-16T13:06:57,911][INFO][o.e.g.DanglingIndicesState] [master] gateway.auto_import_dangling_indices is disabled, dangling indices will not be automatically detected or imported and must be managed manually [2021-06-16T13:06:58,707][INFO][o.e.n.Node] [master] initialized [2021-06-16T13:06:58,709][INFO][o.e.n.Node] [master] starting ...

Thanks for sharing your solution! Also please note that there is no such thing as a slave in Elasticsearch 🙂 ---
