Smile Error when create second Software Raid devices?


Hi, RHEL5 create first software raid is ok,but when create second software raid have a errors?

# mdadm --verbose --create /dev/md0 --level=5 \--raid-devices=3 /dev/sda5 /dev/sda6 /dev/sda7

This i am finish and success create first software raid device.



# mdadm --verbose --create /dev/md1 --level=5 \--raid-devices=3 /dev/sda8 /dev/sda9 /dev/sda10

When create second software raid devices than having a error some thing like " /dev/md1 not found in directory"....

I have try to remove all software raid device and recreate first raid device, and using name " /dev/md1 " still cannot, why only can using name " /dev/md0" ?
