This is what is picked up eg on my machine I have 4 disks in a RAID5 thus: md3 : active raid5 sdd4[3] sdc3[2] sdb2[1] sda1[0] 1465151808 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] So the raw partitions are sda1 sdb2 sdc3 sdd4 If I look at sda: # fdisk -l /dev/sda Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 60801 488384001 fd Linux raid autodetect That's where the "fd" needs to be. -- rgds Stephen
