raid on a pi 4

  • Hi. I'm running OMV 5 on a pi 4 with an external (powered) 2 TB HDD. I have several laptop drives lying around and want to run them off a 4-port powrered USB hub. Can I add them and set up raid without affecting the 2 TB drive?

  • Yes but the usual advice is don't use raid on USB drives. It's not supported through the OMV web interace so you'd have to do it via the command line. A better alternative is UnionFS/SnapRaid which is OK with USB drives and caters for drives of different sizes which is likely your case.

    Thanks. Are they available as a plugin?
