I tried following the instructions at: http://people.freebsd.org/~rse/mirror/ and couldn't make it work. I ended up installing a minimal installation on one disk, reooting to the new install, doing atacontrol create RAID1 ad4 ad6, then rebooting to the install CD and installing into ar0. This seems to have worked. Is your solution better? - ------------------------------ Mike Loiterman grantADLER Tel: 630-302-4944 Fax: 773-442-0992 Email: mike@ascendency.net PGP Key: 0xD1B9D18E -----BEGIN PGP SIGNATURE----- Version: PGP 8.1 iQA/AwUBQjeMnWjZbUnRudGOEQJc9QCg2HAycZ+65GrsJsdEAdinpX/oCOIAnAxn 4jrBbh1vGKr/aNeB93+2VxrP =9Q3N -----END PGP SIGNATURE-----
