Hi community, I'm using Ceph version 16.2.13. I tried to set default_storage_class but seems like it didn't work. Here is steps I did: I already had a storage class name COLD, then I modify the user default_storage_class like this: radosgw-admin user modify --uid testuser --placement-id default-placement --storage-class COLD after that, user info has show correctly: radosgw-admin user info --uid testuser { ... "op_mask": "read, write, delete", "default_placement": "default-placement", "default_storage_class": "COLD", ... Then I put a file using boto3, without specify any storage class: s3.Object(bucket_name, 'testdefault-object').put(Body="0"*1000)) But the object still jump into the STANDARD storage class. I don't know if this is a bug or did I miss something? Thanks
