Understanding allocation_id

Elastic Stack Elasticsearch
1

Hi

I'm new to elastic search and I would like to know if there is any relationship between (allocation_id)
GET /_shard_stores?status=green ... ... "allocation_id": "**40ymWcrHSWSARPNdO8mLfA**"

and the directories I find in data path (/var/lib/elasticsearch/nodes/0/*****)?

Is there any reason why I should know where index'es (shard master/replicas) are stored on node's filesystem?

Thanks

Nope. All interactions should happen via APIs :slight_smile:

No, there is no relationship between allocation IDs and the paths on disk. Instead, these are the index UUIDs, which are fixed for the lifetime of an index.
