I think you're right.  I've lost the raid every time when I pulled out 
the boot drive.

Yea, I think for these reasons I will use lvm.  I have set up a system 
as follows:

/boot raid 1 200mb 4 drives no spares (I guess this makes 4 copies of 
the data?)
2 250mb raid1 arrays over the 4 drives (2 drives each ) for swap
rest of space in 2 raid 1 arrays
lvm on top of the 2 raid1 arrays
/ 10gb on lvm
/data 50gb on lvm
/backup 250gb on lvm

rest of space left free to allow for resizing and adding of partitions 
with lvm

I will pull out a drive tommorow and see how resilient this is.  Does 
this sound like a good solution?
