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=/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 (1UL << OBJ_DEFAULT_OBJ_ORDER) And i do not find the define for OBJ_DEFAULT_OBJ_ORDER, if someone knows , please tell me. Thanks a lot. -- 谦谦君子 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
