Is it possible to boot a Linux system that has suffered unfixable
primary superblock corruption in the root filesystem (ext2)? I know the
mount command can be supplied an alternate superblock with the sb
option, but AFAIK, the earliest this can be done is by setting the
option for the failing partition in /etc/fstab. But of course, root
must already be mounted for that to apply.
Is there any Way to specify an alternate superblock to initrd to mount
the root filesystem?
Can you boot to a live CD, fix the errant partition, and then reboot?
Finnix should do you.
Actually, the problem isn't with my system, but with that of an
acquaintance, and no, the primary superblock refuses to be fixed with
e2fsck -b executed from Ubuntu LiveCD.
Maybe you can use one of the alternate superblocks when running e2fsck
on that filesystem. After all, that is why they are there.
That's what e2fsck -b does.
