[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
