Will groub ever be able to boot RAID1 (from any disk in the array by default) ? I hate when something that works get's replaced with something "smart". And I still havent seen an answer to why grub is so great, to me it seems like it doesn't really work as booting pretty much is the main attaction in boot loaders.
It will boot RAID1 - or more accurately it will boot from an underlying partition. You just have to do the install command manually because it doesn't figure out the underlying devices that make up up the md device.
No one-liners here. But there's that two-liner in the above referenced article ;-)
Well a two-liner for each disk that has to be typed into the grub thingy, no fun when running RAID1 with 2 spares, can't this be put into a script?
I agree that it would be nice if this were automatic, but with grub at least you only have to do it once so it's not a real showstopper. With lilo you had to repeat the install at every change to the config, kernel or initrd. There is also an issue in automating this regarding where the alternates appear in case the boot disk(s) fail. With scsi and most failure modes, the subsequent drives shift up as far as bios and the /dev/sd? devices are concerned. With IDE, they keep their original bios and /dev/hd? names but most failures will also take out any drives sharing the same controller and prevent booting until you physically remove the bad one anyway. I'm not sure what to expect with SATA.
