Are you sure that atacontrol is in sync with the kernel ? the ioctl =20
interface changed some time ago.
At any rate UNLESS your disks are on a "write metadata" supported =20
controller, the rebuild wont  survive a boot since the metadata =20
cannot be written back to the disks. The kernel will complain to this =20=

fact if it applies to your system.
