NonRAID - unRAID storage array compatible kernel driverNonRAID is an fork of the unRAID system's open-source md_unraid kernel driver for supported kernels, but targeting primarily Ubuntu 24.04 LTS, enabling UnRAID-style storage arrays with parity protection outside of the commercial UnRAID system. Unlike in UnRAID, where the driver replaces kernels standard md driver, the NonRAID driver has been separated into it's own kernel module ( md_nonraid ). It's important to understand that many things related to automatic detection etc mentioned in the UnRAID storage management docs: https://docs.unraid.net/unraid-os/manual/storage-management are handled by the commercial UnRAID system, and not by the array driver component. Superblock fileArray state is kept in a superblock file, that is stored outside the array and read by the driver when the driver module is loaded. before starting the array, which causes the driver to not consider parity disks as invalid when creating an array, and thus skipping needing reconstruction.
