Elasticsearch, Failed to obtain node lock, is the following location writable

Question

Elasticsearch won\'t start using ./bin/elasticsearch. It raises the following exception:

- ElasticsearchIllegalStateException[Failed to obtain n         


        

Answer 1

I got this same error message, but things were mounted fine and the permissions were all correctly assigned.

Turns out that I had an 'orphaned' elasticsearch process that was not being killed by the normal stop command.

I had to manually kill the process and then restarting elasticsearch worked again.
