Which part -- the booting or the mdadm 2TiB support? The former I've
talked about on this list before. There's not much to say on the latter.
mdadm-1.6.0-2 (still current in RHEL4, AFAIK) says "Cannot get size of
/dev/sda4: File too large", e.g., when an array member is > 2TiB. I
downloaded mdadm-1.11.0.tgz from
<http://www.cse.unsw.edu.au/~neilb/source/mdadm/> (which was current at
the time), did 'rpmbuild -tb' on it, and installed the resulting RPM,
