[ceph-users] How can I get tail information a parted rados object

Hello. I'm trying to export objects from rados with rados get. Some objects bigger than 4M and they have tails. Is there any easy way to get tail information an object? For example this is an object: - c106b26b.3_Img/2017/12/im034113.jpg These are the objet parts: - c106b26b.3__multipart_Img/2017/12/im034113.jpg.2~fjrC5r_KCWMBat_4bFVtmBv9pxcVL-9.1 - c106b26b.3__shadow_Img/2017/12/im034113.jpg.2~fjrC5r_KCWMBat_4bFVtmBv9pxcVL-9.1_1 - c106b26b.3__shadow_Img/2017/12/im034113.jpg.2~fjrC5r_KCWMBat_4bFVtmBv9pxcVL-9.1_2 - c106b26b.3__multipart_Img/2017/12/im034113.jpg.2~fjrC5r_KCWMBat_4bFVtmBv9pxcVL-9.2 As you can see the object has 2 multipart and 2 shadow object. This jpg only works when I get all the parts and make it one with the order. order: "cat 9.1 9.1_1 9.1_2 9.2 > im034113.jpg" I'm trying to write a code and the code gonna read objects from a list and find all the parts, bring it together with the order... But I couldn't find a good way to get part information. I followed the link https://www.programmersought.com/article/31497869978/ and I get the object manifest with getxattr and decode it with "ceph-dencoder type RGWBucketEnt decode dump_json" But in the manifest I can not find a path to code it. It's not useful. Is there any different place that I can take the part information an object? Or better! Is there any tool to export an object with its tails? btw: these objects created by RGW using s3. RGW can not access these files. Because of that I'm trying to export it from rados and send it to different RGW.
