Before running the 'make savedefconfig' step, make sure to have the ceph required configuration enabled, either by writing the config options directly in the .config file or by running; ./scripts/config --module CEPH_FS ./scripts/config --module CEPH_LIB ./scripts/config --enable CEPH_FSCACHE ./scripts/config --enable CEPH_FS_POSIX_ACL then the remaining make savedefconfig mv defconfig arch/x86/configs/my_defconfig (make sure that they are configured before compiling the respective ersions). The rest remains the same in the procedure, but you need to make sure the ceph support is enabled in the config you use. Hope this help, Regards, Salvatore
