How did you uninstall grub?
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.
What's the output of

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?
menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-686' --class debian
--class gnu-linux --class gnu --class os {
insmod raid
insmod raid5rec
insmod mdraid
insmod part_gpt
insmod ext2

linux /vmlinuz-2.6.32-5-686 root=/dev/mapper/vg_01_ziggurat-root ro
quiet
initrd /initrd.img-2.6.32-5-686
}
This menuentry looks OK to me.
(Is /dev/md0 a symlink to /dev/md/0 or the other way around?)

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.
