说明
dmraid discovers and activates software RAID sets using the Linux device-mapper. It supports various hardware RAID metadata formats including those from Intel, NVIDIA, VIA, and other motherboard RAID controllers. The tool reads RAID metadata from drives and creates device-mapper mappings that present the RAID array as a single block device. This enables Linux to work with "fake RAID" or "firmware RAID" commonly found on consumer motherboards. dmraid operates independently of the RAID controller's BIOS, allowing arrays to be used even without controller-specific drivers.
