Unassigned Shard

I see a previous post from you about the same sort of issue here:

Unable to allocate index

Hi All, I´veen facing issue with an elasticsearch cluster, that first out of the blue, and later after a restart failed to allocate an index. The cluser has a single node atm and replication is disabled. When I check allocation status I see: GET {{elastic}}:9200/_cluster/allocation/explain?pretty&include_yes_decisions=true > { > "index": "logstash-2019.10.04", > "shard": 0, > "primary": true, > "current_state": "unassigned", > "unassigned_info": { > "reason": "ALLOCATION_FAILED…

Did you try the same diagnosis steps as before? I.e. does ls /usr/share/elasticsearch/data/nodes/0/indices/50zRNBhxT3qdJpUdS4B47Q/0/index/ show a file called _1a4.fdt but ls /usr/share/elasticsearch/data/nodes/0/indices/50zRNBhxT3qdJpUdS4B47Q/0/index/_1a4.fdt reports No such file or directory? If so there's something fundamentally wrong with your filesystem again.
