How can I fix my Elasticsearch cluster that won't start?
First, let's check the logs. Can you find the Elasticsearch log file and share any error messages you see?
I found a message saying 'max virtual memory areas vm.max_map_count is too low'.
This error indicates that the virtual memory limit is set too low. You can increase it by running: 'sysctl -w vm.max_map_count=262144'.
I ran that command, but the cluster still won't start.
Make sure to restart Elasticsearch after changing the setting. If it still doesn't start, check for any other error messages in the logs.
