Duo V2 one disk expansion

You need to add a second 3TB disk to get expansion, or backup your data, then do a factory reset (wipes all data, settings, everything) and restore data from backup.

Oppps .... thanks for reply
Very bad news !
No way to extend existing volume (i have root and ssh open ) ?

Hi All,
I am using Ready NAS Duo v2 and since I have similar questions I would like to reconfirm what do I need to do.
I have hardly any knowledge of RAIDs and NAS.

I have bought 4TB drive to ultimately replace the 1TB which came with the device. I added it to NAS, it munched for some time and then as I understood it - created XRAID2 of size 1TB on both disks.

I believed that it would be enough to take out old disk to have the size expanded to 4TB but after several attempts it always remained at 1TB. After reading the response to this post I understood that NAS will not automatically expand the volume of larger drive to use its full capacity, is this correct?

If yes then I need to back NAS up, perform a factory reset and restore the data to larger drive from the back up - correct?

I have not fully comprehended how to make a NAS back up to the local PC from reading a manual. Can you help me out with navigating to proper option?

Would there be a problem with restoring data from back up if I change RAID modes, e.g. to JBOD of 5TB size?

Many thanks for your advice!

When you installed the 4 TB drive, XRAID2 migrated you to RAID-1. Volume size is 1 TB to match the smallest disk.

Removing the 1 TB drive then results in the volume being degraded. However it is still 1 TB. You can purchase a second 4 TB drive, and insert it in the empty (or 1 TB) slot. That will expand to 4 TB, and will be protected.

The simplest way to back up your NAS to a local PC is to drag/drop the folders on the NAS to PC folders. I suggest downloading teracopy, and using it's verification mode. It will take longer, but it ensure that everything is properly copied.

There should be no problem restoring the folders. After the reset you will need to recreate the shares (putting some of them on the 1 TB volume, and the rest on the 4 TB volume).
