Are you running with raid1 on raw sda and sdb or are you creating
partitions and running raid on the partitions (which to me is the normal
thing to do)?

If you are running raid on the raw device, then grub-install would have to
be on /dev/md0 or whatever your raid device is.  If you have partitions,
then it would be on /dev/sda and /dev/sdb.

If you have no partitions, then doing grub-install /dev/sdb probably
broke the raid.  It's such an unusual and weird setup to not use
partitions that most people simply assume you have partitions and any
advice you get will make that assumption.  Somewhat makes it a dangerous
setup to use for that reason.

Lennnart,
Thank you for that information.  And sorry to everyone else for any wrong information I gave out.  In everything I read I didn't know grub2 would install to md0.  good to know.
