Fixed In Version:	ceph-20.1.0-18	Doc Type:	Enhancement
Doc Text:	New Ceph Object Gateway S3 support for IBM COS accelerated archive Previously, restore operations for the S3-Cloud-Glacier type with IBM COS failed because the system passed Glacier-specific parameters intended for AWS, which were not applicable to other cloud vendors. With this enhancement, the system introduces a new `glacier_restore_tier_type` value, `NoTier`, to handle these scenarios and enable successful restores for IBM COS accelerated storage class (equivalent to AWS Glacier). For more information, see the Compatibility Matrix and Transitioning data to IBM Cloud Object Store (COS) service.	Story Points:	---

Description Vidushi Mishra 2025-05-08 13:49:49 UTC

Description of problem:


Enable support in Ceph RGW for S3 object restoration from the IBM Cloud Object Storage (COS) Accelerated storage class, which is the IBM equivalent of AWS Glacier. Ceph supports object transitions and restorations to/from AWS Glacier. However, equivalent workflows fail when interacting with IBM COS Accelerated, with the following error:

ERROR: Restore request received result: ExpeditedRetrievalNotAvailable

This RFE requests Ceph RGW to handle IBM COS Accelerated restore requests (both Standard and Expedited) gracefully and compatibly.
