And how do I know all these mirror data mismatches are Swap?  does not 
each mismatch mean the mirrors disagree, which means one of them is 
wrong.  Which one?  since they aren't timestamped or checksummed (like 
vxvm, zfs do), I am playing 'data maybe'.    As someone who adminstrates 
database servers, i have a real problem with that.

btw, this is centos 5.4+latest x86_64, its primarily running postgres, 
and our inhouse java middleware apps.  and was going to be a oracle grid 
operations server.
