If I owned the equipment I would put the 4 drive raid in a bigger box
with more drives.  But I don't trust our colo to do the work.  They
also setup the mysql partition w/o LVM, idiots.

A few people have assured me that rsync'ing multiple times during and
after the db is running and then stopped will work.

I have about 1.2TB of data to move.  I have yet to be convinced that a
mysql dump and restore is worth the time.  If the rsync fails it's my
last option.

In the future a enterprise san would be great or a clustered fs.
