Re: arm, both disk able to boot (raid1)


When the 1st raid disk (which is able to boot) fails, an other method to restore the system might be to mount the 2nd disk (which isn't able to boot), on the laptop and make it able to boot via chroot right?

                 If your raid1 setup is done, just update your fstab and run
        "update-initramfs -u && flash-kernel" to update the initramfs
                 with the
                 new fstab and install the initramfs to flash. I'd
        advice you to
                 have a
                 serial console in case something goes wrong.

             Thanks. I've no experience with a serial console. Tutorials
        on the
             web seems to edit also the grub files, which aren't on this
        ARM install.
             What should be done different on a ARM in comparison with this
             method for instance?
