i use raid1 inside my xen guests and if i need to resize the domu fs i remove 
one disk, grow it, re-add it and rebuild the raid1. Same for the other disk. 
Then i resize the raid1 and then i can online resize the fs. I do this since 
2006 and it works without problems, only bad thing is the complete rebuild of 
the raid1, but you don't have to reboot your domu!
