Rescue software RAID system

[William Muriithi]

Evening,

I am curious if someone has gone through this, I have a centos 6 system
with the operating system running on RAID 1 (software based).

Sometimes over weekend, one of the drive failed. That exposed a mistake I
did when setting up the RAID. It looks like grub is pointed to one of the
disk, which unfortunately happen to be the broken one.

I have tried a bit of things that don't seem to work. My biggest hope was
to repoint grub from hd0 to hd1. I did that from the grub prompt and didn't
work. Seem to still be poking the dead drive instead of the good pair.

So I booted from a rescue CD, used mdadmin to start RAID device, mounted
the device and tried to chroot into the mount directory and don't work,
don't seem to have chroot binary in my rescue environment.

Will give it another try tomorrow but can someone see a problem with this
approach?  Or rather, how did you guys approach it?

Any advice would be highly appreciated.

Regards,
William
