Expand ReadyNAS 422 from one 4TB drive with second 2TB drive

[OldManAndHisNAS]

I have existing ReadyNAS 422 at firmware 6.10.6 with one 4TB drive X-RAID JBOD.

Would like to add a second drive.  It is a 2TB drive.

Thought I could add to the 2nd slot for 6TB of total JBOD capacity without any RAID protection.

I can't see that it will let me do this.  

Is this limitation of Netgear or am I doing something wrong?

Thanks!

I think you can (though it's been a while since I played with this).  BTW, one risk when you span two drives w/o RAID protection is that when either drive fails you will lose all the data on both.  So it's not a setup that I recommend.

You need to first turn off XRAID - if there is a green bar on the XRAID control, click on it to switch to flex raid.

Then you can expand the volume by creating a second RAID group on the 2 TB disk, and concatenate the two groups.

If you can't figure out how to expand it, you can create a second volume on the smaller drive, and move some of your shares there.

You do need to turn off XRAID to accomplish that.

can you give me some points on how to do this without turning off XRAID?

thank you.

It cannot be done with XRAID enabled.  

XRAID will

1. ignore any drive smaller than 4 TB
2. Give you RAID-1 mirroring with any drive 4TB or larger (with no increase in capacity).
