Am I doing something weird when I do on a ceph node (nautilus, el7):

rbd snap ls vps-test -p rbd rbd map vps-test@vps-test.snap1 -p rbd

mount -o ro /dev/mapper/VGnew-LVnew /mnt/disk <--- reset/reboot ceph node

Hi Marc, It's not clear where /dev/mapper/VGnew-LVnew points to, but in principle this should work. There is nothing weird about mapping a snapshot, so I'd suggest capturing the kernel panic splat for debugging. Thanks, Ilya
