Hello,

    qemu-img convert -f qcow2 Trove---mysql-5.6---2015-07-16.qcow2 -O raw
rbd:openstack-00/8205d01a-874c-44c0-b114-1c03821fcc24:conf=3D/etc/ceph/ceph=
.conf

   How can i specify the object size that rbd uses?  I found that the
qemu-image can only use the default object size. It is defined in
block/rbd.c

    #define OBJ_MAX_SIZE
<https://lxr.missinglinkelectronics.com/qemu+v2.1.0/+code=3DOBJ_MAX_SIZE>
(1UL << OBJ_DEFAULT_OBJ_ORDER
<https://lxr.missinglinkelectronics.com/qemu+v2.1.0/+code=3DOBJ_DEFAULT_OBJ=
_ORDER>
)

    If someone know how to specify the object size, please tell me. thanks
a lot.
    By the way i do not find the define for  OBJ_DEFAULT_OBJ_ORDER
<https://lxr.missinglinkelectronics.com/qemu+v2.1.0/+code=3DOBJ_DEFAULT_OBJ=
_ORDER>,
if someone knows , please tell me. Thanks a lot.
