hi,
i have two placement

{
        "key": "placement-1",
        "val": {
            "index_pool": "default.rgw.buckets.index",
            "data_pool": "default.rgw.buckets.data",
            "data_extra_pool": "default.rgw.buckets.non-ec",
            "index_type": 0,
            "compression": "" 
        }
    },
  {
        "key": "placement-2",
        "val": {
            "index_pool": "default.rgw.buckets.index",
            "data_pool": "default.rgw.buckets.test",
            "data_extra_pool": "default.rgw.buckets.non-ec",
            "index_type": 0,
            "compression": "" 
        }
    }

i create 2 buckets ,
s3cmd mb s3://test1 --bucket-location=default:placement-1
s3cmd mb s3://test2 --bucket-location=default:placement-2

upload 10M file to test1 and the copy test1/10M to test2/10M_copy with boto3

from boto3.session import Session
import boto3
access_key = "yly"
secret_key = "yly"
session = Session(access_key, secret_key)
url = "http://127.0.0.1"
config_dict = { 'signature_version' : 's3', 'connect_timeout': 30000, 'read_timeout': 30000}
config = boto3.session.Config(**config_dict)
s3_client = session.client('s3', endpoint_url=url, config=config)
print s3_client.copy_object(Bucket="test2", Key="10M_copy", CopySource=str('test1'+'/'+"10M"))

and then remove objs
s3cmd rm s3://test1/*
s3cmd rm s3://test2/*

and process gc

radosgw-admin gc process --include-all

and this two shadow file left and can not be remove by gc
