Elasticsearch: Node suddenly stops working with no shards available exception
0
I have a single node elk installation which was working fine up until I discovered that kibana was unable to connect to elasticsearch.
systemctl status elasticsearch
● elasticsearch.service - Elasticsearch
Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2018-12-28 14:21:33 EET; 5min ago
Docs: http://www.elastic.co
Main PID: 1193 (java)
Tasks: 87
Memory: 3.0G
CPU: 5min 39.675s
CGroup: /system.slice/elasticsearch.service
├─1193 /usr/bin/java -Xms2g -Xmx2g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+AlwaysPreTouch -Xss1m -Djava.awt.headless=true -Dfile.encoding=
└─1548 /usr/share/elasticsearch/modules/x-pack-ml/platform/linux-x86_64/bin/controller
but here is a gist with the exceptions;
for some weird reason after a restart the node seems to recover.
How can this behavior be explained?

Can you successfully run any requests against Elasticsearch? Like maybelocalhost:9200/_cat/nodes?

Looks like the node with ELK installed experienced a crash and all shards have been unassigned. The shards re-assigned once the node was healthy again most likely fixed by the restart. Check in the logs if you see errors concerning ELK crash

Looks like the node with ELK installed experienced a crash and all shards have been unassigned. The shards re-assigned once the node was healthy again most likely fixed by the restart. Check in the logs if you see errors concerning ELK crash
