In one of my environment Orient Me suddenly stopped working and even a reboot of your Linux machine did not help. My colleague Matt Milza pointed me in the right direction to solve this issue: Check your systems disk space with df . You may be seeing that your / has run out of space:
Unfortunately there is a bug in the first release of Orient Me that will continue writing logs into
/var/lib/elasticsearch/data/elasticsearch-default/nodes/0/indices
until all space is used:
The solution is simple: Delete all content in this folder ( rm -rf * ) and restart your machine. Then Orient Me should be happily working for you again. A fix is being built.
Update: As Ben Williams pointed out, Christoph Stoettner has documented how permanently fix this issue here.
Even better is to follow the steps in https://www.stoeps.de/orient-me-elasticsearch-and-disk-space/ to ensure the Elasticsearch indices are cleaned up.
Good point! I must have missed this blog entry.
