Please don't post images of text, they are impossible to search for later and cannot be read by those of us using screen readers (and tbh this one is almost impossible to read even for sighted readers). Instead please share the contents of the logs and config files, formatted using the `` button so it looks as you are seeing it. ---

It's better, though not perfect. At least I can see it now. Use the `` button and check the preview window: ```nohighlight preformatted text ``` I don't think this message is what Elasticsearch reported, I think you've edited it and now it doesn't make sense. Would you share the actual logs that Elasticsearch reports without editing? ---

```auto an election requires at least 2 nodes with ids from [bYUUn1SOTpmtXK3NcjEuCw, RKYlzwmcSyyK3YoV8T5YJw, ru42fueKTYWDuaUhgGkXuQ] an election requires 2 nodes with ids [ru42fueKTYWDuaUhgGkXuQ, mRFp_9x1T4ea_2KHEUzdyQ] an election requires 2 nodes with ids [QhLl9zbgQt6mQku_yLTqNw, ru42fueKTYWDuaUhgGkXuQ] ``` I see at least 5 node IDs here, which means either you have 5 nodes or else you have wiped the data paths of some nodes causing them to generate new IDs. If you did lose the contents of the data path then this cluster is broken, the simplest fix is to wipe everything and start from the beginning again. ---
