Regarding multiple posts on the current ata driver in 5.4 not supporting hardware mirroring with the Intel ICH5R and ICH6R chips ... My 2 cents is to use gmirror for software mirroring as is described in http://dannyman.toldme.com/2005/01/24/freebsd-howto-gmirror-system/ There is another method, which I have also used, that has the advantage of not needing to go into Fixit mode using the 5.4 boot CD (hence it can be executed remotely); however, it takes more typing and more reboots. It is described here: http://people.freebsd.org/~rse/mirror/ If you use the latter, note that Ralf uses ATA drives ad0 and ad1, while your SATA configuration will probably come up as ad4 and ad6. You need to make the transliteration 0 --> 4 and 1 --> 6 very carefully, especially in the line for the boot loader where ad(1,a) --> ad(6,a). This latter paper also outlines how to mirror at the slice, rather than the disk, level. One final hint: if you are playing around with gmirror on the same disks, you can get into a situation where one attempt has left gmirror information on the last sector of your disks. This will confuse gmirror, and you will have to load and use gmirror to clear it out. Read the man pages on gmirror in any case!!!
