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?)

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. -mz -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Re: GRUB no long gives menu on boot
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.
