I haven't messed with nvidia raid in a while but AFAIK it uses dm (device mapper)/dmraid to make devices for the nvidia fakeraid but the raw block device (/dev/sdX) are still accessible. There is no reason you should not be able to run smartctl on the block devices themselves while the machine is running to get smart info.

I would think if you:

cat /proc/partitions

You would see the sdX devices (raw devices) as well as /dev/mapper/nvXXXXX or whatever its naming scheme was. Again.. its been a while.

I've installed a fake raid array using Nvidia raid.

I was hoping there would be a command that I may be able to check the 4 drives behind it as it is my main backup area...

Thanks for any help!
