RAID on partitions, with boot disk

    Hello.


    I tried to search for this, but I didn't found a reply.


    I have the following configuration (manually created)


    /dev/sda1 15 GB Boot disk with OMV
    /dev/sda2 200 GB
    /dev/sdb1 15 GB
    /dev/sdb2 200 GB


    I'd like to create a RAID 1 between /dev/sda2 and /dev/sdb2, but when I try to do it, I don't see the partitions (nor the disks), listed there.
    Can I create such a RAID in OMV?


    Thanks for your help.

    you have to create id manually as OMV does not allow and manage any data on your boot device (sda).


    Beware, this can destroy everything, if you do it wrong or make a typo in it.


    You can create a raid on those partitions like that:

    Code
    mdadm --create --verbose /dev/md0 --level=1 /dev/sda2 /dev/sdb2
mdadm --detail --scan >> /etc/mdadm/mdadm.con


    After rescanning you should see a RAID array within the OMV GUI.

    Everything is possible, sometimes it requires Google to find out how.
