Filesystem retention not working

Grafana Loki
1

Hello,

I want to purge all chunks older than 31 days in loki so I set this config

schema_config:
  configs:
    - from: 2020-10-24
      store: boltdb-shipper
      object_store: filesystem
      schema: v11
      index:
        prefix: index_
        period: 24h

storage_config:
  boltdb_shipper:
    active_index_directory: "/var/lib/loki/boltdb-shipper-active"
    cache_location: "/var/lib/loki/boltdb-shipper-cache"
    cache_ttl: 24h 
    shared_store: filesystem
  filesystem:
    directory: /var/lib/loki/chunks

compactor:
  working_directory: "/var/lib/loki/boltdb-shipper-compactor"
  shared_store: filesystem

chunk_store_config:
  max_look_back_period: 0s

table_manager:
  retention_deletes_enabled: true
  retention_period: 31d

version: 2.4.1
but this is not working.
Did I forget something to set ?

Hi,

Did you wait for deletion, there is a relevant discussion in Github i suggest you have a look at it first :

Hope it helps.

Good Luck

actually starting in version 2.4.0 it’s necessary to update the configuration to purge old data, by

  • defining the retention period in section limits_config
  • activate the retention in section compactor

which gives

 compactor:
  retention_enabled: true
limits_config:
  retention_period: [30d]

this is explained in the upgrade document I did not know about

Hello，The chunks are deleted or not? I’m having a problem with full disk space

Same here, getting disk space issue with loki 2.4.1. Did you got the solution
