Now try to get the first disk to fail in such a way that it remains visible to the BIOS but it no longer works, or no longer serves the boot sector correctly, and see how that goes. That's the kind of scenario you might be willing to protect against, right? Unfortunately, in this case, it won't renumber the disks, and the system won't boot up. > md0 is /boot and everything else is on md1 (LVM).

This is exactly what you're tell grub when you change the device mapping. -- Alexandre Oliva http://www.ic.unicamp.br/~oliva/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org}
