mounting foreign root volume (multiple root volumes) causes panick - toasters

3 Jan 2003


      Does anyone know if you can mount two (or more) root volumes on one filer
and how tell it which on to boot from?
I had a filer/shelf with a corrupt vol0.  However there was user data on
there I wanted to get at.   So I mounted it on another test filer whose
root volume was named boot, but the filer now complained about having two
root volumes (boot and vol0).

I was trying to boot both as readonly so I could boot off a previous
inode on the corrupt vol0.  Anyone know if there is a way to specify
which volume to boot from when you are mounting multiple root volumes on
one filer?   I've already gotten the data in another fashion but I thought
it should be able to mount two root volumes on one filer.
