A quick and dirty way to create such a mirrored array (RAID1) on a new system is to boot off the FreeBSD install CD, do a minimal scratch install, abort out of the post install questions, and at the command line issue the com- mand: atacontrol create RAID1 ad4 ad6 then immediately issue a reboot and boot from the installation CD again, and during the installation, you will now see "ar0" listed as a disk to install on, and install on that instead of ad4, ad6, etc. ............. in my case the machine showed me the ar0 to install the system on it without doing this 'quick and dirty way'. and now i get: # atacontrol status ar0 ar0: ATA RAID1 status: READY subdisks: 0 ad4 ONLINE 1 ad6 ONLINE that tells me that i actually do have RAID1 active. which means it's a software one, correct? also if you do not mind please elaborate on "MatrixRAID is one of those not-really-raid controllers that onlyprovides RAID during the boot process..." thank you...
