I was afraid of that.
I'm not directly mounting sda/sdb in the dom0, but they are members of a
MD RAID1 that the dom0's root fs is on so... yeah, I'm hosed.
Is there any way to run a command on the dom0 from the domU?  Other than
say ssh'ing over the network.  Really what would be ideal is if there is
a way to just pass a command through to the dom0 from the domU.  Is that
even possible?
Thanks again.
