Yes, and if you don't get to GRUB, what do you do?
Lilo is also able to boot from different disks (MBR)
I very much prefer a Linux software raid setup myself, but you are
depending on the quirks of your BIOS if your primary boot drive dies.
We _are_ speaking about SW Raid. Once you have your bootloader, BIOS
is not anymore involved. And if this bootloader is able to boot from
another MBR, why not using this feature ;-)?
All our servers are seted up in SW Raid1 with the GRUB fallback
option: it's working very well.
I am talking about SW Raid also. Now, what happens when your BIOS fails
to read the MBR from the first mirror and doesn't try the second because
it sees the first?
I see this problem, and I do not know how to fix it without either
replacing the BIOS or installing a PCI disk controller that handles this
scenario properly.
Let me repeat, if your BIOS doesn't look hard enough for a MBR, you will
never get to the bootloader.
I'm looking for solutions, do you understand the problem I am
describing? I hope so, because otherwise you are just denying a valid
failure case.
Solutions wanted.
Mike
