1) use `rbd info $pool/$image` to get object name prefix for this image (block_name_prefix field); 2) use `rados -p $pool ls | grep "^$block_name_prefix"` to generate a list of all existing objects for this image; 3) for every object from the list use `rados -p $pool stat $object` to get its size; 4) for every object from the list use `ceph osd map $pool $object` to get its location; 5) group obtained data by osd. Though I expect it will be very slow. For Filestore, instead of using `rados` and `ceph osd map` you could ssh to every osd node and use e.g. find+stat to get necessary data for all files (objects) with $block_name_prefix in their name. -- Mykola Golub _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
