Hello, I am having very strange and serious problem, which I could not have the right MD device name from /proc/partitions. I created md1,2,3,4 but it shows "md0" for all as you can see from the following "cat /proc/partitions". arm-raid# mdadm -C /dev/md1 -l1 -n2 /dev/hdb5 /dev/hdd5 mdadm: array /dev/md1 started. arm-raid# mdadm -C /dev/md2 -l1 -n2 /dev/hdb6 /dev/hdd6 mdadm: array /dev/md2 started. arm-raid#mdadm -C /dev/md3 -l1 -n2 /dev/hda5 /dev/hdc5 mdadm: array /dev/md3 started. arm-raid#mdadm -C /dev/md4 -l1 -n2 /dev/hda6 /dev/hdc6 mdadm: array /dev/md4 started. arm-raid#cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid5] read_ahead 1024 sectors md4 : active raid1 hdc6[1] hda6[0] 1024000 blocks [2/2] [UU] md3 : active raid1 hdc5[1] hda5[0] 1024000 blocks [2/2] [UU] md2 : active raid1 hdd6[1] hdb6[0] 1024000 blocks [2/2] [UU] md1 : active raid1 hdd5[1] hdb5[0] 1024000 blocks [2/2] [UU] unused devices: <none> arm-raid#cat /proc/partitions major minor #blocks name 9 1 1024000 md0 9 2 1024000 md0 9 3 1024000 md0 9 4 1024000 md0 3 0 120060864 hda 3 1 16600 hda1 Any clues? suggestions?
