Advice point 1; read my howto: http://wiki.tldp.org/LVM-on-RAID  If
you see anything that doesn't work, let me know so I can fix it.

	I read through it, thanks.  I'll let you know if anything you
mention is broken -although I doubt it.

Advice point 2; which my howto should mention: For boot devices you'll
probably want to use the 1.0 mdadm label format (not 1.1 or 1.2, which
are the same but change where the label is stored) for just the boot
raid 1.0 only.

Oops!  I already created a 1.2 Superblock.  Well, no biggie.  I'll just
trash it and do it over.  The /boot array is tiny, so it doesn't take long
at all to create.

 It will also mention some things you should be extra
careful about...

Like mounting the bare devices in that raid set by mistake.

	Uh... yeah.  That could be ugly.  That's why I like to have a cold
drive on the shelf configured with the entire OS.

Oh, and you'll also very likely want grub to read the /boot
filesystem, which is why it must be on a partition followed by the
raid header, instead of a partition containing a raid header and raid
protected partition.  That use is OK since grub operates read-only.

	I think I follow you, here.  IOW, partition the drive, create the md
target, and then format the RAID array, right?  Or are you saying one should
format the partition and then create the RAID array on top of it?
