RAID on raspberry pi with quad sata

  • Hi everyone,

    First of all, big thanks to everyone as I've always found a solution for my problems on the forum.
    Exept for this one...

    I've just received my rock pi quad sata hat so happy I could try out a RAID 5 configuration. I had trouble seeing all my 4 drives (4 HDD 2.5" 1To each) but with the help of the forum I finally succeeded.

    Now here is my problem : when I try to create a RAID device, none of the hard drive appears on the devices panel. I can see them when I click on disks, and they even appear in the SMART panel. The only difference I see in the SMART panel is the status of 2 of the hard drive is grey instead of green and temperature is N/A. This is weird to me as all the drives are the same size and brand.

    I'm not sure what information would be useful but I'm eager to give you some output.

    Hope we'll find a way around this.

  • This is not USB devices

    Yes it is, where or how do you believe the hat communicates with the Pi.

    Actually the Quad Sata Rockpi kit is specifically intended for that kind of setup

    No it is not, it allows you to connect 4 drives via a sata connectors.

    It uses a JMS561 which is a sata to usb bridge.

    You can set up a raid via the command line have a look on youtube there are plenty of 'gurus' on there who will use a Pi in a raid config.

  • If the HAT is not intended for this kind of setup it's yet what they suggest on their wiki

    "A complete NAS solution" does not imply a Raid, you can setup a Pi using a single drive, it's still a NAS.

    This where new users fall down, they assume that a NAS uses a Raid setup by default and that's thanks to the number hardware nas systems in the market.
