First find the name of the snapshot associated with snapshot id b740 (46912) via "rbd snap ls <image-spec>", then run rebuild on that particule snapshot via "rbd object-map rebuild <image-spec>@<snap name>". Unfortunately it did not work : I can't succeed in finding the broken snaphot. I have parsed all the snaphots of all the images in a loop, where I get all the SNAPIDs. But none of these IDs is 46912 ! " Please, can you tell me how did you get this number 46912 or a link which explain that ?You wouldn't need to search all images, it's tied to image "MY_IMAGE". Have you tried "rbd snap ls --all MY_IMAGE"?
Yes : now I got the broken snapshot with the --all flag.In fact this snapshot was in the namespace "trash" that's why I couldn't find it with "rbd snap ls"
@list : the id b740 is hexadecimal, we need to convert it in decimal in order to get the id 46912
Thanks a lot for you answers and for the real good job done on Ceph ! Rafael
