Unnable to list snapshots in Elasticsearch repository

KA3AXCTAH · April 27, 2021, 5:57pm

I have an Elasticsearch snapshot repository configured to folder on NFS share, and i'm unable to do list snapshots because of strange errors

curl -X GET "10.0.1.159:9200/_cat/snapshots/temp_elastic_backup?v&s=id&pretty"

{
  "error" : {
    "root_cause" : [
      {
        "type" : "parse_exception",
        "reason" : "start object expected"   
      }
    ]
    "type" : "parse_exception",
    "reason" : "start object expected"
  },
  "status" : 400
}

What version are you running?
What is the output from POST /_snapshot/temp_elastic_backup/_verify?

KA3AXCTAH · April 28, 2021, 7:14am

i'm using 7.4.1 version
and here is output

im create another vm and install the latest version of ES (7.12.1) and get this error

dadoonet · April 28, 2021, 8:29am

You need to remove the > characters.

KA3AXCTAH · April 28, 2021, 8:46am

excuse me, from where?

dadoonet · April 28, 2021, 9:14am

From here

KA3AXCTAH:

curl -X PUT "localhost:9200/_snapshot/old_anthill_efk_nopci?pretty" -H 'Content-Type: application/json' -d'

> {

>   "type": "fs",

>   }

> }

> '

KA3AXCTAH · April 28, 2021, 9:55am

fixed

dadoonet · April 28, 2021, 10:05am

So did you exactly run that?

curl -XPUT "localhost:9200/_snapshot/old_anthill_efk_nopci?pretty" -H 'Content-Type: application/json' -d '{
   "type": "fs",
   "settings": {
     "location": "/opt/elasticsearch-backup/efk-anthill-nopci-14.03.2021",
     "compress": true
   }
}'

Or something else?

KA3AXCTAH · April 28, 2021, 5:19pm

yeah! i run this on the new machine, and it throws error

KA3AXCTAH · April 29, 2021, 9:46am

and i have another snapshot repository ( separate dir on NFS share) that thorws this error when i'm try to list snaps
and error the same as

dadoonet · April 29, 2021, 11:44am

So you are probably doing something which is not exactly that but I can't tell...
May be do a screenshot?

Here is what I have when I run this exact command locally:

{
  "error" : {
    "root_cause" : [
      {
        "type" : "repository_exception",
        "reason" : "[old_anthill_efk_nopci] location [/opt/elasticsearch-backup/efk-anthill-nopci-14.03.2021] doesn't match any of the locations specified by path.repo because this setting is empty"
      }
    ],
    "type" : "repository_exception",
    "reason" : "[old_anthill_efk_nopci] failed to create repository",
    "caused_by" : {
      "type" : "repository_exception",
      "reason" : "[old_anthill_efk_nopci] location [/opt/elasticsearch-backup/efk-anthill-nopci-14.03.2021] doesn't match any of the locations specified by path.repo because this setting is empty"
    }
  },
  "status" : 500
}

Which is expected. But at least my request is correct.

KA3AXCTAH · April 30, 2021, 6:04am

This errors happens because you don't specify

path.repo setting in your elasticsearch.yml file

dadoonet · April 30, 2021, 6:39am

I know that.

I'm just showing you that the request is correctly parsed and then it fails.

In your case, the request can not be read correctly.

KA3AXCTAH · April 30, 2021, 6:40am

Sorry for my bad english, this is my scenario
I have 6 node elasticsearch cluster for logs, and i have a cronJob that executes snapshots all of my indicex to NFS share ( Folder on NFS ) so when i'm try to list snapshots this error appears

curl -X GET "10.0.1.159:9200/_cat/snapshots/temp_elastic_backup?v&s=id&pretty"

{
  "error" : {
    "root_cause" : [
      {
        "type" : "parse_exception",
        "reason" : "start object expected"   
      }
    ]
    "type" : "parse_exception",
    "reason" : "start object expected"
  },
  "status" : 400
}

and on this cluster if i
POST /_snapshot/temp_elastic_backup/_verify
it will execute for hours and no reply

but i create another fresh vm and install elasticsearch ( 7.4.1 version on it) and registered this repo on this vm
so register completed without errors, the next step is verify this repo

curl -X POST "localhost:9200/_snapshot/temp_elastic_backup/_verify?pretty"

{

  "nodes" : {

    "WNjRRRJXTuajOXHp542R9w" : {

      "name" : "loges-prod-15-uv03"

    }

  }

}

so as you can see the snapshot verifies without errors, the next step is to list snapshots

curl -X GET "localhost:9200/_cat/snapshots/temp_elastic_backup?v&s=id&pretty"

{

  "error" : {

    "root_cause" : [

      {

        "type" : "parse_exception",

        "reason" : "start object expected"

      }

    ],

    "type" : "parse_exception",

    "reason" : "start object expected"

  },

  "status" : 400

}

same error appeared...

dadoonet · April 30, 2021, 7:00am

The first error is weird.

curl -X GET "10.0.1.159:9200/_cat/snapshots/temp_elastic_backup?v&s=id&pretty"

Does not have any body to parse. So I don't see what is happening.

Could you share the full elasticsearch logs?

KA3AXCTAH · April 30, 2021, 7:35am

Here is the logZ

Nothing wrong here. Is there any reason why I can see blank lines in every single post you are posting?

Could you run again:

curl -X GET "10.0.1.159:9200/_cat/snapshots/temp_elastic_backup?v&s=id&pretty"

And do a screenshot and attach it here?
