Index setting "plugins" : { "index_state_management" : { "auto_manage" : "false" } creating problem

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
1.2.4

Describe the issue:
I installed opensearch with index_management enabled. I have few indices in my cluster, all indices were in green state and i do not have this parameter
“plugins” : {
“index_state_management” : {
“auto_manage” : “false”
}
in any of the index setting.

Later i restarted opensearch ,then i got that setting in 2 of the indices.

This setting is causing problem when i rollback to Opensearch version where i disabled ISM. Those 2 indices are in red state after rollback.

Can anyone please help if there is any way we can delete this particular parameter from the index setting?

You can reset the setting to null by this:

PUT logs-2024.02.01/_settings
{
  "plugins": {
    "index_state_management": {
      "auto_manage": null
    }
  }
}

Hi @gaobinlong , i reset it and it worked. Thanks.
But without removing any policy on that index, why that parameter is showing up after i restart the pods?
Can you clarify me here?

Did you check that setting before you restart the pods? I think that setting was set when you configured ISM policy for the new created indices in OpenSearch with ISM plugin installed.

Hi @gaobinlong , i checked the setting of that index before restart, it was not there.
Is there anyway it created due to any conflict of any setting?

Hi @gaobinlong ,
If we are removing policy manually from an index, we are getting this parameter in setting of that particular index.

“plugins” : {
“index_state_management” : {
“auto_manage” : “false”
}

But if we add policy manually to that index again, still this setting is appeared, until i set it to null manually.
Why cant this parameter is removed when we reapply the policy to that index?
Can i get help here?
