Hi, I have a couple of FreeBSD 8.2-STABLE (as of 25/08) boxes. These have onboard RAID 'type' controllers. The OS is installed on 'ar0' (e.g. /dev/ar0s1d et'al). Additionally I've installed the smartmontools port - which monitors drive SMART attributes. Am I ok setting this up to access the 'underlying' devices for ar0 (which are also exposed by the OS) - e.g. as '/dev/ad12' and '/dev/ad14' - at the same time as obviously data is being read / written to '/dev/ar0' (which comprises both those disks as a RAID1 array)? Cheers, -Karl
