Hi,
I had to do this a while ago, basically you have to mark the disk as failed (if not already) and than remove it from the array
mark as failed > mdadm --fail /dev/md0 /dev/sdaX
remove from array > madmad --remove /dev/md0 /dev/sdaX
Partition your new disk to your needs and then add it to the array using mdadm again
mdadm --add /dev/md0 /dev/sdbX
to check the status of the array
mdadm --detail /dev/md0
Hope this gives you a starting point.

Dear all, I'm not used to handling software raid. I've inherited a server which has raid 10 set. one of our disks failed, and it's to be replaced today. My question is; any hint how to add this new disk to the existing raid array ? first thought is :- Create identical partitions as other disks in the array i'd like to add it to.- add it to raid. Though i'm extremely worried of messing things up and wiping all my data. Any hint would be appreciated _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
