RN104 added 6TB to a 4TB and its now raid1 how to make new volume with the 6TB drive

I was using an RN104 with a single 4tb drive till it run out of space. Now i bought a 6tb drive and forgot (or rather i didnt know) to switch to flexraid before inserting the new drive. As a result I now have a 4tb-6th raid 1 combo.

How do i seperate those volumes safely and add a diffrent volume to the nas that uses the 6tb drive?

  • You had a single disk JBOD, now it's a RAID1 on two drives. You can use tricks to make a new JBOD volume on the new drive, but you can't revert your RAID1 to a JBOD, at least from the GUI (decreasing the number of RAID devices in the volume). Search this forum, this has been discussed before. 

    Ful backup + recreating the volumes is the way to go (using the GUI anyway).

  • Once the RAID reshape started, you can't go back. I'm afraid you'll have to destroy the volume. This will wipe it, so you'll have to do a full backup first.

      Wait why? Its raid1 theoretically when i take one drive i should be able to read it in any computer. So why cant i take the 6tb and make it a separate volume?
