Curator delete_indices fail

pollux · June 11, 2018, 12:48pm

Hi,

I'm aware of this topic:

I'm using ES 6.2.4 ans curator 5.5.4

My config.yml is:

client:
  hosts:
    - es1.corp.net
    - es2.corp.net
    - es3.corp.net
  port: 9200
  timeout: 30
logging:
  loglevel: DEBUG

actions.yml

actions:
  1:
    action: delete_indices
    description: >-
      Delete indices older than 30 days, metricbeat
    options:
      ignore_empty_list: True
      disable_action: False
    filters:
    - filtertype: pattern
      kind: prefix
      value: metricbeat-
    - filtertype: age
      source: name
      direction: older
      timestring: '%Y.%m.%d'
      unit: days
      unit_count: 30

This curator config is running every day in a fesh docker container. It's not working since y upgrade from 6.2.3 to 6.2.4.

client = elasticsearch.Elasticsearch(hosts='es1.corp.net')

client.indices.stats(index='metricbeat-6.2.3-2018.05.24', metric='store,docs')
{'_shards': {'total': 2, 'successful': 2, 'failed': 0},
 '_all': {'primaries': {'docs': {'count': 766735, 'deleted': 0},
   'store': {'size_in_bytes': 281425602}},
  'total': {'docs': {'count': 1533470, 'deleted': 0},
   'store': {'size_in_bytes': 563361892}}},
 'indices': {'metricbeat-6.2.3-2018.05.24': {'primaries': {'docs': {'count': 766735,
     'deleted': 0},

   'total': {'docs': {'count': 1533470, 'deleted': 0},
    'store': {'size_in_bytes': 563361892}}}}}

and (partial) debug log:

Do you have an explanation ? In advance Thanks

How was curator installed in the docker container?

We'll see a lot more if you add an empty blacklist to your logging section, as follows:

logging:
  loglevel: DEBUG
  blacklist: []

The default behavior does not show the elasticsearch and urllib3 log traffic.

I use this container in prod : https://hub.docker.com/r/bobrik/curator/

but for test I create a clean virtualenv on my machine an pip install it:

virtualenv -p python2 .venv
source .venv/bin/activate
pip install elasticsearch-curator
.venv/bin/curator --version                                                               
curator, version 5.5.4

Complete log is 306 line long, I cannot paste it here what are the relevant part ?

2018-06-11 17:02:46,617 DEBUG elasticsearch log_request_fail:110 &lt; {"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"metricbeat-6.0.1-2018.05.10","index_uuid":"_na_","index":"metricbeat-6.0.1-2018.05.10"}], "type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"metricbeat-6.0.1-2018.05.10","index_uuid": "_na_","index":"metricbeat-6.0.1-2018.05.10"},"status":404}

This indicates that there's something amiss in your cluster. Something says that metricbeat-6.0.1-2018.05.10 exists to Curator (an API call), but then when it issues another API call to delete it, Elasticsearch is responding with {"type":"index_not_found_exception","reason":"no such index". It's not there. Are all three hosts in your config.yml part of the same cluster?

  hosts:
    - es1.corp.net
    - es2.corp.net
    - es3.corp.net

If these are not all members of the same cluster, and that index is not on all members, that would result in the "not found" response. Curator round-robins the requests. The first request hits the first host, and then the delete hits the second. This is the most likely explanation of what is happening.

pollux · June 12, 2018, 7:19am

Yes all this hosts are part of the same cluster, and there is no unassigned shared that what bother me

If I retry with just 1 host it work... So Maybe it's a problem with my ES cluster and not with curator.

Thanks for your help. My first conclusion was the same as yours, but I cannot believe there are index inconsistency in the cluster. Apparently it can

EDIT: ok.... So ashame of this. One of the host got out of the cluster and I didn't notice... It didn't raise alarm in the monitoring system, so it was completely my fault... sorry.
