  • I uderstand everything you've said so far, but the one question nobody seems to be able to answer for me is: What happens if the parity drive fails? You explained that uRaid does NOT use striped parity, so all the parity data must therefore be contained on one drive. So if THAT drive fails, what are your options?

  • @2000jago Even Parity drive CAN be rebuilded from the info in the other drives.

  • @PoltergeistLamb But if (as stated here) parity data is not stored on the other drives in the array, how's this possible?

  • Comment removed

  • @2000jago The same way it rebuild one drive in the array.

    When parity drive fails, when you replace with a new parity drive it will be restored using the bits in all the other drives in the array. See from 1:39, Imagine that you are replacing a parity drive, this is the process of the rebuild.
