there is no official support for xfs in RHEL5, so that is not an option.
Besides, I'm talking about a drop of >150mb/s to ~10mb/s read performance
when cracking the 2.2T size. This is clearly not in the ext3 (or FS for
that matter) magnitude of performance issues. Also, numbers stay the same
when dd'ing on the raw device (LUN).
