One of our newly installed boxes had a diskcrash today, luckily it was in a 2-disk softraid mirror. Both disks are sata, and I have successfully exchanged the defective drive with a new one. Raid has been resynced ok. BUT, I cannot boot from any of the two disks since the boot disk is the one that died. "grub-install /dev/sda" tells me this: "/dev/md0 does not have any corresponding BIOS drive" /dev/md0 is /boot This bug shows that this is a LONG TIME standing bug: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=55484 -HK
