Default GRUB no long gives menu on boot

Greetings,

I have the following setup which worked well after performing a squeeze install:

/boot -> Software RAID5
/ -> LVM on top of Software RAID5

I lost a disk of my RAID array a few months ago and ever since
replacing it and rebuilding the arrays, I no longer get a menu of
kernels to boot from in GRUB. Instead I get a prompt.

I have tried reinstalling GRUB from a Squeeze rescue flash drive, but
there is no change.

Comments and help appreciated.

Thanks,

-mz

A suggestion. You may have lost the mbr when the disk failed. If you completely reinstalled your system oncluding reformat of drives that option should have been offered. Do you recall that occuring.

I never uninstalled grub.

There was/is a bug in grub that it cannot read a degraded RAID array.
That was biting me at one point, but I replaced the drive and rebuilt
the array.

Hmmm. If I recall correctly, I installed GRUB to the MBR on /dev/sda,
but /dev/sdc was the disk that died.

Who knows - my memory isn't that good.

I did not completely reinstall my system. I just used the Squeeze
rescue option which includes an option to reinstall GRUB.

1) You should install grub to /dev/sdc with either grub-install or grub-setup.

2) I'm surprised at the "looks for (vg_01_ziggurat-root)/boot/grub". I
would've expected a "looks for looks for (md/0/grub)".

How are you booting from the grub prompt?

Is it a regular or a rescue grub prompt?

What's the output of "ls" and "set" at the grub prompt?

This menuentry looks OK to me.

(Is "/dev/md0" a symlink to "/dev/md/0" or the other way around?)
