I would like to know how data is stored in ES when using multiple paths  
Each folder paths are RAID0. If a hard disk fails, how does ES allocate the data?

Any help is appreciated. Thank you

If any of the data paths fails (i.e. becomes unwritable) then the whole node is dropped from the cluster and its shards will eventually be rebalanced across the remaining nodes.
