Raid 0 on controller, one volume, still 2 drives in Storage

[Catalin Enache]

hi there. Sorry for noob question: I created one volume (raid 0) in Hp Smart array 120i but still, in Freenas 9.3 storage I see two separate disks which can be configured in Mirror or Stripe. Is freenas completely ignoring the HP Smart Array configuration? Thanks

I'm guessing smart array is fake raid.

Why on earth would you want a hardware raid for Freenas disks? Have you read any of the documentation or warnings?

Actually its not fake. i forgot to mention that the main data storage is already on a Z1 raid (IBM M1015). I created a second hardware raid for other reasons (HP Microserver gen 8 is lowering its fan when sensing a raid config on its 120i controller).

If the disks are presented to the OS as separate disks then it's fake raid.

Any type of RAID occurring between the disks and the motherboard, ANY type of RAID (fake, real, red, blue, up, down) that's not controlled by FreeNAS, is a terrible accident waiting to happen with FreeNAS and/or ZFS.

well...It might be something wrong in the config, but for sure its a raid controller embedded in motherboard

Anyway, I will just set it back to AHCI

Just because it's built into the motherboard doesn't mean it isn't fake raid. Every fake raid I have used have been built into the motherboard

It's fakeRAID: http://h18013.www1.hp.com/products/...arraycontrollers/dynamicsmartarray/index.html

HP Dynamic Smart Array is a RAID solution combining a storage host bus adapter (HBA) and proprietary software components.

Also, I can't help but be reminded of obligatory xkcd.
