Spare migration doesn't work for external metadata. mdadm skips a container with spare device because it is inactive. It used to work because GET_ARRAY_INFO ioctl returned valid structure for a container and mdadm treated such response as active container. Current implementation checks it in sysfs where container is shown as inactive. Adapt sysfs implementation to work the same way as ioctl.
