I have an action file with 7 steps. ````auto --- actions: 1: action: rollover description: >- Rollover index -logs-* options: name: active--logs #Enter alias name not index name conditions: max_age: 1d new_index: "" extra_settings: index.number_of_shards: 2 index.number_of_replicas: 1 index.routing.allocation.include.box_type: hot continue_if_exception: False disable_action: False #True 2: action: alias description: add search alias to all indices options: name: search-index-logs disable_action: False continue_if_exception: False #True add: filters: - filtertype: pattern kind: prefix value: index-logs- 3: action: alias description: >- Add alias to new index and remove active index from old index options: name: active-index-logs disable_action: False #True continue_if_exception: False add: filters: - filtertype: pattern kind: prefix value: index-logs- - filtertype: age source: creation_date #timestring: '%Y.%m.%d' direction: younger unit: days unit_count: 1 remove: filters: - filtertype: pattern kind: prefix value: index-logs- - filtertype: age source: creation_date #timestring: '%Y.%m.%d' direction: older unit: days unit_count: 1 4: action: alias description: add inactive alias options: name: inactive-index-logs disable_action: False #True continue_if_exception: False add: filters: - filtertype: pattern kind: prefix value: index-logs- - filtertype: age source: creation_date #timestring: '%Y.%m.%d' direction: older unit: days unit_count: 1 5: action: index_settings description: >- Set old indices to read-only options: disable_action: False #True index_settings: index: blocks: write: True continue_if_exception: False preserve_existing: False ignore_unavailable: True filters: - filtertype: alias aliases: inactive-index-logs - filtertype: age source: creation_date direction: older unit: days unit_count: 1 6: action: shrink description: >- Shrink old index-indices to 1 shard options: timeout_override: 300 disable_action: False #True continue_if_exception: True shrink_node: DETERMINISTIC number_of_shards: 1 number_of_replicas: 0 shrink_prefix: inactive- shrink_suffix: null delete_after: False post_allocation: allocation_type: include key: box_type value: hot wait_for_active_shards: 1 wait_for_completion: True wait_for_rebalance: False wait_interval: 30 extra_settings: settings: index.blocks.write: true filters: - filtertype: alias aliases: inactive-index-logs - filtertype: age source: creation_date direction: younger unit: days unit_count: 2 - filtertype: age source: creation_date direction: older unit: days unit_count: 1 7: action: delete_indices description: Delete inactive indexes that are more than X days old options: timeout_override: 300 disable_action: False #True continue_if_exception: False filters: - filtertype: alias aliases: inactive-fusion-logs - filtertype: age source: creation_date #timestring: '%Y.%m.%d' direction: older unit: days unit_count: 7``` The issue is that after running step 5 where the index settings are successfully updated with `index.blocks.write: True` In the shrink step the index setting changes to `index.blocks.write: False` .

Hi @fidsamuraiCrelio, I just checked the documentation in which it is mentioned that "Make Index read only". As you can see the below Shrink API document where the value is assigned as null. > **[Shrink index API | Elasticsearch Guide \[master\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-shrink-index.html)** we can't perform any write operations once index is in shrink state.

@harshbajaj16 Step 5 of my action file makes all indices older than 1 day get the setting of `index.blocks.write: True`. The issue is that when I run the shrink action(Step 6) for some reason it changes the setting to - `index.blocks.write: False` Using Curator just FYI ---

Hi @fidsamuraiCrelio , Yes understood and have seen in step 6 u have mentioned 1 day that's why it is changing the value from true to false. indices are going to shrink state with write value as false because Elasticsearch shrink operation doesn't allowed us to write on shrink indices.

@harshbajaj16 , Sorry could you explain it again? From what I understood from the doc the shrink operation will only work if we make the index read-only right? I've provided a suffix to the new index so that it will create as inactive-index-logs-(datestamp) In that case only the new index needs write permissions right? Or am I missing some important step? ---

@harshbajaj16 , Okay so I went through the documentation again. I think I understood my mistake. In step 6(shrink) in `extra_settings` I'd put `index.blocks.write: True` instead I need to put `index.blocks.write: null` is that correct? ---

Hi @harshbajaj16, I tried the new setting but it still doesn't work, our old index setting still changes from `index.blocks.write: True` to `index.blocks.write: False`. Anything else I can try? ---

@harshbajaj16 , We currently use ES 6.2.2. We're using Curator instead of ILM as that was introduced in ES 6.8+. Steps we want to take - 1. Rollover index everyday. 2. Add "search" alias on all indices 3. Remove "active" alias from rolled over index and put it on the new index. 4. Add "inactive" alias on rolled over index. 5. Change index setting of old index to block writes. 6. Shrink index. 7. Delete any indices that are older than 7 days. Let me know if you need any further details. ---
