The program is in attachment. WARNING: USE IN AT YOUR OWN RISK, NO WARRANTIES ARE PROVIDED!!! IT MAY CORRUPT YOUR DATA!!! You need to install rados-dev and compile the program with: gcc ./upd_parent.c -o upd_parent -lrados To change ID of parent image pool you need to run it with following arguments: ./upd_parent <old_wrong_pool_id> <new_correct_pool_id> <image_pool_name> <image_name> for example (lost pool was 13, new pool is 20, image pool name is "volumes"): ./upd_parent 13 20 volumes volume-c083800d-7688-4fb8-9230-83643cbe8927 Hope, it will helps. I recommend you to try to mount fixed image read-only, copy all important data (if possible) and only after that try to boot it or run fsck.
