X-Pack license expired so I thought I had uninstalled it...
root@elkstack:/usr/share/elasticsearch# bin/elasticsearch-plugin remove x-pack
-> removing [x-pack]...
ERROR: plugin [x-pack] not found; run 'elasticsearch-plugin list' to get list of installed plugins
root@elkstack:/usr/share/elasticsearch#
root@elkstack:/usr/share/elasticsearch# bin/elasticsearch-plugin list
root@elkstack:/usr/share/elasticsearch#
But if I look in Dev Tools ---
qrSYXO4 localhost 127.0.0.1 ml.machine_memory 270376742912
qrSYXO4 localhost 127.0.0.1 xpack.installed   true
qrSYXO4 localhost 127.0.0.1 ml.max_open_jobs  20
qrSYXO4 localhost 127.0.0.1 ml.enabled        true
Is there no way to remove it? Thanks!
