Maybe you should ask Redhat?? It's a little bit more complex than that. The mdadm package in rhel is responsible for boot up bring up of md raid arrays, and between rhel5 and rhel6 we changed boot loaders, changed init scripts, changed over to doing udev incremental assembly, and a host of other things. I have resisted the urge to put mdadm 3.x on rhel5 because it behaves differently and the particular quirks of mdadm 2.6 might or might not be relied upon by those boot scripts. So, my latest build for rhel5 is mdadm-2.6.9-3. Now, whether or not even just that much of an update would work with something as old as rhel5.3 with its (I'm sure) not updated mkinitrd or initscripts is another question. --=20 Doug Ledford GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband --------------enigE02A6B77585767410282A67F Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5FY3cACgkQQ9aEs6Ims9gjMgCeJRQiIuVgJHbthrZ+eNXTbICh bocAoNRW/nspEqLhv91BMZMPml3MqdtB =HDzv -----END PGP SIGNATURE----- --------------enigE02A6B77585767410282A67F--
