Taneli,



Thanks for the information.



That gives me two other questions:



(1) This is for the folks at Xensource responsible for the binary distribution
-- if md support under Xen requires the md drivers to be compiled into the
kernel, why does the binary distribution from Xensource have them built as
modules?



(2) I've tried adding mdadm to the initrd, and it complains that
/dev/md0 and /dev/md1 don't exist.  In fact, they *do* exist on the initrd
filesystem *prior* to starting udev; after udev starts I'm not positive (didn't
have much time to fiddle with it this morning).  Even running mdadm with 
--auto=yes
fails to create the device nodes.  *Should* this work?  Or is it simply not
possible to use the md drivers built as modules under the Xen kernel?



Thanks,



  -- Lars
