Unable to create elasticserach backup on glusterfs

Elastic Stack Elasticsearch
1

I have 3-node elasticsearch cluster. I had issue where snapshots were not created. At that time I did not have shared filesystem across all three nodes. So I went ahead and used glusterfs to create shared filesystem. Now when I try to create a snapshot. I get the same error.

Input:

$ curl -X PUT "localhost:9200/_snapshot/my_backup" -H 'Content-Type: application/json' -d'
>{
>   "type": "fs",
>   "settings": {
>     "location": "my_backup_location"
>   }
> }
> '

Output:

It would be nice to get some opinion on use of glusterfs.
