PUT /_snapshot/es_temp/snapshot_all_indices_new
{
"indices": "index1,index2" ,
"ignore_unavailable": "true",
"include_global_state": false

}

when i check snapshot status

GET /_snapshot/es_temp/snapshot_all_indices_new/_status

i am getting the following exception can u please explain me why it is coming

Exception message

{
"error": "IndexShardRestoreFailedException[[index1][0] failed to read shard snapshot file]; nested: FileNotFoundException[/shared/test/es_bkps/es_temp/indices/index1/0/snapshot-snapshot_all_indices_new(No such file or directory)]; ",
"status": 500
}

Is /shared/test/es_bkps actually a shared mount between all nodes?

hi

yes it was shared mount between all nodes.one more point here when i do individual index backup and status check it is working fine. but when i do group of indices backup and status check it is failing

4

Do you get the same error regardless to what node you issue the command?

5

yes i have two nodes in my cluster and i have tested on both nodes still getting same error

6

Can you post here the output of ls -al /shared/test/es_bkps/es_temp/indices/ from inside both nodes?

I could not reproduce your issue and your setup seems to be fine. Also, even though 1.5 is rather old and many bugs has been fixed, I could not find any relevant issue related to this error.

I suggest that you check NFS logs both the clients and also in the server and look for potential problems.
