I'm going to have take the server offline again for some extended downtime.

It seems that I'm having some difficulty rearranging the data on the 
drives while all the Xen sessions are online (probably due to kernel 
bugs).  I really need to do that, as running the software RAID in a 
degraded state seems to be somewhat fragile.  There are some other 
issues to address as well.

So I'm going to take the server offline so I can rebuild things in 
single user mode.  I'm not sure how long it will take -- I'm guessing 
that it may take between 10-20 hours.  Hopefully, I can get the VMs back 
online for tomorrow.
