Hello!
Why after change directory elasticsearch data path, service failed to start.
I change path in elasticsearch.yml to my directory. I make chown elasticsearch to directory and set chmod 777, but whithout changes...
I changed the path.data: /opt/logs in elasticsearch.yml.
After changes i can't start service and i have this error -

ExecStart=/usr/share/elasticsearch/bin/elasticsearch -Des.pidfile=${PID_DIR}/elasticsearch.pid -Des.default.path.home=${ES_HOME} -Des.default.path.logs=${LOG_DIR} -Des.default.path.data=${DATA_DIR} -Des.default.path.conf=${CONF_DIR} (code=exited, status=1/FAILURE)

# This is correct

Anyway, why do you mix your data and logs?

path.data: /opt/logs

looks a wrong directory IMO.

But the problem is:

Feb 03 17:15:01 graylog elasticsearch[12512]: # There is insufficient memory for the Java Runtime Environment to continue.

I'm not mix them, just create directory with name logs)) Ok, can are you explain me please, right steps for change data path in elastic?
