Hello! It doesn't look that you have created image format 1 images. I have created images in Jewel (10.2.0 and also som erlier releases) with the switch --image-format 1 and seems to work perfectly even if it's a depreciated
switch and causes warnings i have used it successfully with krbd and Ubuntu 14.04. The image format is going to stop workning i future releases as I understand så using this should probably just be used if you don't plan to use them
for production for an extended time. Regards Stefan Från: ceph-users
