When using "rbd create ... --image-format 2" in some cases this CMD is rejected by EINVAL with the message "librbd: STRIPINGV2 and format 2 or later required for non-default striping" But, in v0.61.9 "STRIPINGV2 and format 2" should be supported [root@rx37-3 ~]# rbd create --pool SSD-r2 --size 20480 --order 16 --image-format 2 --stripe-unit 65536 --stripe-count 4 t2 rbd: create error: (22) Invalid argument 2014-03-11 14:39:03.885185 7f15bc170760 -1 librbd: STRIPINGV2 and format 2 or later required for non-default striping [root@rx37-3 ~]# ceph -v ceph version 0.61.9 (7440dcd135750839fa0f00263f80722ff6f51e90) Any hints ?
