The one gotcha in this setup (other than not being able to boot from the big RAID5 arrays, since each is >2TiB) is that the version of mdadm shipped with RHEL4 does not support array members bigger than 2TiB. I had to upgrade to an upstream release to get that support.
I would be interested in hearing the details on that. I ended up hunting down all the mdadm stuff and recompiling everything from SRPMs.
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, which worked.
Heh, not the booting. 8-)
OK, so we basically did the same thing with mdadm then. I think I'm running 1.12.mumble and it seems to be up to version 2 now. I've not fiddled with it at all since the install since it was working OK and I didn't want to upset the apple cart.
