Thread: RAID1 updating MBR on second hdd

  1. RAID1 updating MBR on second hdd

    Hi,

    It's rather unfinished feature rather tahna a bug but nevertheles.
    When installing (etch, i don't know if bug occurs in lenny) using
    software RAID1 (or any other? [5,6,10]) installer only installs
    grub in the MBR of one of HDD's. I know i can manually do the second
    install later and add to grub propper lines, but i think it should be done
    automatically (while updating kernel/modules problem with automatically
    updating menu.lst also emerges). The thing is when one of hdd dies
    system should start up. Its the philosophy of RAID1, and i know that
    i can do a hardware RAID1, but not on low-end servers, in small company
    when price is the main factor.

    Regards
    Piotr Jablonski

    Indeed. This missing feature has already been reported (#391489) but no
    one ever proposed an implementation.

    In the meantime, it is possible using preseeding to install GRUB on
    multiple disks at once, with something like:
    d-i grub-installer/bootdev string (hd0,0) (hd1,0) (hd2,0)

    Cheers,
