I know, that format2 in rbd.ko is supported with kernel version 3.10 and above. But, if I want to create an rbd-image only the Ceph Userland services should be involved, shouldn't it ? -Dieter BTW the kernel version on the nodes hosting the OSDs processes is 2.6.32-358.el6.x86_64 but I can also boot with a 3.10.32 kernel.
