    Raider seemed a really cool system for something rather complicated. Thanks. I am using Ubuntu 12.04 LTS server with a 2T sda single drive. I wanted to convert it to RAID1. Everything went smoothly with the first half. It rebooted fine after switching the newly RAID-ed drive to the sda slot and the original drive to the sdb slot. I verified that the RAID drive was the boot drive with df -h and checked to see that sdb was recognized with fdisk -l. I ran 'raider --run' according to the instructions and got this error:

    root@server1:/home/dadmin# raider --run

    :: raider version 0.13.2 started
    :: Conversion to Raid
    :: RaidSync phase started...


    :: You are not running in "single user" mode.
    :: Do you want to continue without changing to single mode? (y/[n])y


    :: Detected /dev/sda as part of the new system
    :: FATAL ERROR: /dev/sdb is not connected in the correct slot.
    :: New disk must be connected to the last slot!

    I have tried connecting /dev/sdb (original non-RAID drive) in what would be sdb, sdc, and the fourth sdd, but I keep getting the same error message.

    What can I do to get the original drive mirrored with the RAID sda. Thanks

    I was able to override this error message by going to the GUI for the system http://url:10000, selecting the Hardware menu on the left, and selecting Linux RAID option. From there for each partition I selected "add partition" selecting the corresponding partition on sdb. There were two partitions md0 and md1. After mirroring md0 (the boot), I did the same for md1. It is still in process but should be successful.
