Every 4-7 days one of my indexes get broken.
OS: Debian 9.3 4.9.0-6-amd64
curl -XGET http://hostname:9200/_cat/indices | grep red red delivered HotrN1eGQpmxTkbJN0oL0g 5 1 36618688 1476436 1.8gb 1.8gb ls /var/lib/elasticsearch/nodes/0/indices/HotrN1eGQpmxTkbJN0oL0g/ 0 1 2 3 4 _state
I have checked every of 5 indexes like this:
java -cp lucene-core-6.6.1.jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex /var/lib/elasticsearch/nodes/0/indices/HotrN1eGQpmxTkbJN0oL0g/0/index/ -verbose -exorcise
No problems were detected with this index.
Can you please suggest me something ?
The problem was in broken server. I don't know what exactly but they changed everything except disks and I have never see again such problems.
