Hi list,
i've configured a raid1 and i'm trying to install grub on it. But it
doesn't work.
~# grub-mkdevicemap -n
~# cat /boot/grub/device.map
(hd0) /dev/disk/by-id/ata-INTEL_SSDSA2CW160G3_CVPR14530C6J160DGN
(hd1) /dev/disk/by-id/ata-INTEL_SSDSA2CW160G3_CVPR145101F9160DGN
~# grub-install /dev/md127
error: found two disks with the index 0 for RAID md/raidone.
error: superfluous RAID member (2 found).
error: found two disks with the index 0 for RAID md/raidone.

"$grub_setup" ${allow_floppy} ${setup_verbose} ${setup_force}
--directory="${grubdir}" --device-map="${device_map}" "${install_device}"
When i then add /dev/md127 to my device.map i got this:
~# grub-install /dev/md127
error: found two disks with the index 0 for RAID md/raidone.
error: superfluous RAID member (2 found).

Installation finished. No error reported.
But the device still does not boot. Installing grub to sda / sdb does
not work either as they do not contain any partition table. What's wrong
here?
