I have been able to setup a RAID-0 array with a single disk with no problems. However, adding more than one disk into the array causes grub to generate this error when trying to setup grub: Filesystem type unknown, partition type 0xfd I have tested the following options: RAID-0, 1 drives: OK RAID-0, 2 or more drives: FAIL RAID-1, 2 or more drives: FAIL RAID-5, 3 or more drives: FAIL and to install grub I use the following: grub --no-floppy grub> device (hd0) /dev/hda grub> root (hd0,0) grub> setup (hd0) grub> quit This all used to work ok with LiveCD v2004.0. From looking at the grub ebuild the current grub-0.94-r1 ebuild seems to be lacking the debian raid patch. is this still required for supporting the 0xfd autodetect raid filesystems?
I've just found that support for RAID-1 has been added to grub-0.95, so were part way there. Any idea on how to get it working for RAID-5?
ok, found a work round for this (I think). I'm setting my /boot partition to be a RAID-1 and the rest to be RAID-5. In theory that should make sure the boot information is on all disks and that RAID-5 will still work. will test it out.
