mdadm software RAID doesn't load at boot

  • 772

I'm using mdadm to create a raid1 mirror across two disks. I can create my /dev/md5 array perfectly using the tools, but it does not automatically reload my /dev/md5 when I restart, I need to manually recreate the array.

Am I missing something obvious here?

    make sure your partitions are of type fd: Linux raid autodetect. Also, create the /etc/mdadm/mdadm.conf file, the easiest way is with:

    mdadm --detail --scan > /etc/mdadm/mdadm.conf

    after sucessfully building the array.
