Hi, I posted this question in -Questions about a week ago, and didn't get any replies :( I'm just trying to check - we have a number of 8.2-STABLE amd64 systems where the onboard RAID shows up as '/dev/ar0' (which we use for filesystems, i.e. /dev/ar0s1d et'al), and the underlying devices for that RAID1 array show up as '/dev/ad12', '/dev/ad14'. Is it OK to run smartmontools / smartd / smartctl against the underlying adX devices, whilst ar0 is in use? I can't see anywhere that seems to indicate it's bad - and I can't seem to find anywhere that seems to say it's Ok... Thanks, -Karl
