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.
