Is it possible to have /boot on /dev/md_d0p1 in a RAID5 configuration
and boot with GRUB?

Last I checked, GRUB did not have the RAID drivers to read RAID5 before the kernel was up. It can, however boot from RAID1. Forrest ^ permalink raw reply [flat|nested] 4+ messages in thread

Only if you get yourself a PCI card with a RAID BIOS on it and attach the disks to that. The RAID BIOS hooks interrupt 13 and allows GRUB (or DOS or LILO for that matter) to see the RAID5 array instead of the individual disks. Obviously any RAID card will do, it doesn't matter whether it has a CPU to do the RAID calculations or not (known as fake-RAID and ataraid if it doesn't). ^ permalink raw reply [flat|nested] 4+ messages in thread
