Replacing a failed drive in an md raid1/raid10
- Check if the kernel already removed the faild drive from the arrays:
# mdadm --detail /dev/md0- If not, remove it by hand:
# mdadm /dev/md0 --remove /dev/sda1 - If in an array a partition of the failed drive is not marked as faulty, before removing run
# mdadm --manage /dev/md1 --fail /dev/sda2
- If not, remove it by hand:
- Insert a new physical disk
- Copy the partition table to the new drive from its mirror:
sgdisk -R /dev/sda /dev/sdb(fromsdbtosda)
