Welcome! It could help if you explain what you did exactly to get in that situation. Here it seems that 2 versions are mixed together. ---

Hi, We just shutdown the VM and increase the disk because /var/log/elasticsearh is 100% full.. after that we found that ther service didn't start. # systemctl status elasticsearch ● elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Fri 2020-01-10 13:51:50 PST; 24min ago Docs: [http://www.elastic.co](http://www.elastic.co) Process: 4637 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -p ${PID\_DIR}/elasticsearch.pid --quiet (code=exited, status=1/FAILURE) Main PID: 4637 (code=exited, status=1/FAILURE) Jan 10 13:51:47 elastic01 systemd[1]: Started Elasticsearch.

Pretty sure that something else happened. Like an upgrade which was wrongly executed. ---

Could you share the full elasticsearch logs please? Please format your logs. Paste the text and format it with \ icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer. ---

You have a mix of 2 elasticsearch versions. You should reinstall correctly elasticsearch but keep the `data` dir and the `config` dir. ---
