RAID1

[Marius Korthof]

Hi,

I'm trying to setup a machine with 4 x 500GB disks as a RAID1 of 2 disks and 2 spares. I run FAI 4.0.6 on Debian 7.0.  I pasted  my disk_config below; at the end of this email.  The installation fails at GRUB (see below). If I change BOOT_DEVICE to /dev/sda GRUB installs ok but host doesn't boot (error: fd0 read error at grub boot prompt). I've tried putting /boot on a separate partition outside the RAID but again the machine wouldn't boot to OS. The RAID is created fine:  "/dev/md0  457G  737M  433G   1% /target" and "mdadm --detail /dev/md0" output is as expected. Same goes for md1 (swap). Also there rest of the FAI installation finishes OK.

I'm assuming this RAID1 setup is supposed to work or is this a known problem? Any hints/fixes/workarounds? TIA
