I'm trying to create a software RAID1.

What went wrong? Or, please point out what I missed. :confused: I've tried setting the SATA type in BIOS to either "Native IDE" or "AHCI" modes. If I set it to RAID mode, the installation says "no disks found". When I boot up, either from the CD or from ad4, I see both disks, ad4 & ad6. When I do the "atacontrol create RAID1 ad4 ad6" command and then "atacontrol status ar0", it reports that ar0 is READY, but when I reboot, it's gone. -- View this message in context: http://www.nabble.com/Help-with%3A--atacontrol-create-RAID1-ad4-ad6-tp21511186p21511186.html Sent from the freebsd-questions mailing list archive at Nabble.com.
