Our elasticsearch was working fine and it was storing index on path: $DATA_DIR/nodes/$nodeOrdinal
But suddenly it's down with the below error:
java.lang.IllegalStateException: failed to obtain node locks, tried [[DATA_DIR/Cluster_E3]] with lock id ; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was )?
It's searching for the cluster named folder, which was not happend before and there are no such folder inside DATA_DIR
Elasticsearch- version 5.0.2
