Hi all,
I am currently using opensuse 12.1,
We have Raid 5 array of 8 disks. A friend of mine accidently removed a drive & place it back and also added a new disk to it(making it 9 disks). now the output of mdadm --detail is as shown below
si64:/dev # mdadm --detail /dev/md3

How do I fix this?
Please let me know if you need more info
Thank you,
