What does different between my command and your command?
my command
radosgw-admin object stat --bucket=dev --object="_shadow_test_s3.2/2vO4WskQNBGMnC8MGaYPSLfGkhQY76U.2_7"
your command
radosgw-admin object stat --bucket=dev --object="_shadow_test_s3.2/2vO4WskQNBGMnC8MGaYPSLfGkhQY76U.2_7"
they are the same
If I try use full object name, I receive error
Exemple
[root@rgw-node-2 ~]# radosgw-admin object stat --bucket=test1111 --object="current_structure_Compressor.jpg"
{ "name": "current_structure_Compressor.jpg",
"size": 51249,
"policy": { "acl": { "acl_user_map": [
{ "user": "admin",
"acl": 15}],
"acl_group_map": [],
......
[root@rgw-node-2 ~]# radosgw-admin object stat --bucket=test1111 --object="default.4380.1_current_structure_Compressor.jpg"
ERROR: failed to stat object, returned error: (2) No such file or directory
