Answer

This is what is officially documented when a Storage Nodes LDR service goes read-only. 

  • Read-only: When the desired state is Read-only, the LDR service moves the storage state to read-only and stops accepting new content. Note that content might continue to be saved to the Storage Node for a short time until open sessions are closed.

There is another element to this read-only state not mentioned in documentation. The LDR in a read-only state will accept purge/delete requests either driven by S3 or ILM driven purges. 

  • This will be updated in future documentation. For now, this KB exists to fill this gap.
