Hi Gaël,
What command are you running to format the image?
Is it persistent? After the first formatting attempt fails, do the
following attempts fail too?
Is it always the same set of sectors?
Could you please attach the output of "rbd info" for that image and the
entire kernel log from the time that image is mapped?
Thanks,
Ilya
