Actually, it doesn't matter if you make your md device out of whole disks or not, it's the attempt to find a partition table on the md device itself that is generating this message. This is a side effect of the recent kernel change to allow any block device to be partitioned and merely indicates that no partition table was found on your md device. It's normal. In fact, it might be worth suggesting that the message go away. If there's no partition table people generally know that because there are no partitioned dev files ;-) --=20 Doug Ledford GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband --------------enigCB561381489AF0B989257424 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkr7IroACgkQg6WylM+/8ZQUuACdFtg6/zp45g2f8TtxnkkCnype +9cAoI03jisBFHv8cIYaf8ej4A/AV/XM =NPW+ -----END PGP SIGNATURE----- --------------enigCB561381489AF0B989257424--
