Hi Shashank, I think you should use "rados -p <pool_name> ls" to list all objects in <pool_name>, if there is a image in <pool_name> , like this : root at ceph0:~# rados -p testpool ls rb.0.1017.6b8b4567.000000001806 rb.0.1017.6b8b4567.000000000f32 rb.0.1017.6b8b4567.000000001b5b rb.0.1017.6b8b4567.00000000181f rb.0.1017.6b8b4567.00000000121f rb.0.1017.6b8b4567.000000000278 ...... rb.0.1017.6b8b4567 is image prefix 000000001806 is object id so the output likes this: <image_prefix>.<object_id> I wish this will be help ! best regards min chen ------------------ Original ------------------ From: "Shashank Puntamkar";<spuntamkar@xxxxxxxxx>; Date: Mon, May 26, 2014 02:24 PM To: "ceph-users"<ceph-users at lists.ceph.com>; Subject: How to get Unique object ID of object in ceph I am trying to explore the possibility to use ceph object based storage in software development and client side deployment.I configured Rados gateway.I am able to access data with filename reference using S3 API and various other s3 clients.I wish to use Object ID to access the data rather then file name.Hence I want to know about the Objet ID assignment of files/object in Ceph.Can anyone tell l how to get ObjectID of object in Ceph? Is Ceph provides unique object ID of objects?
