ReadyNAS NV+ v2 disk addition questions
I have an NV+ v2 running a 2TB X-Raid volume over 2 2TB physical disks (so effectively RAID1). One of the disks is failing so I want to do a straight-swap for a new 2GB disk. What is the procedure ...

Just remove the old drive (NAS running) and insert the new one.

Two issues here...
First, you need to be certain that you have a v2, since the older v1 can't handle drives > 2 TB.
An NV+ v2 runs 5.3.x firmware. If you are running something else (4.1.x or 4.2.x) then you don't have a v2. The labels are confusing... So if you aren't running 5.3.x, then post back and tell us what you are running.
Second, if you are running X-RAID you will need to do a factory reset, and set up the NAS in flexraid. That is destructive, so you'd need to reconfigure the NAS and restore the data from a backup. If that's an issue, then expand the existing volume instead.
Hi - it's definitely a V2 (running 5.3.13).
If I expand the existing 2TB X-Raid (2x 2TB physical) with a new physical 4TB disk... how much additional capacity will be created? (I'm assuming not 4TB).
If I choose to go through the re-build route, what is the best way to backup the current x-raid volume. Can this be done directly over the USB port on the unit?

The capacity rule is "sum the disks and subtract the largest". So adding a 4 TB drive would expand the volume by 2 TB. Adding another 4 TB drive would expand it by 4 TB.

You can use the USB port, or you can back it up over the network (say to a USB drive attached to a PC). I don't know which is faster with the v2. On the v1 it's no contest - the USB performance is very poor, so backing up over the network is much faster. If you do back up over the network, I suggest using software that can verify. Teracopy is one option, there are others.
Disks can fail during expansion too, so I recommend doing a backup either way.
Thanks for all your help with this.
Final question for you. If I go down the rebuild route, what's the order of play when I bring the system back up. Should I start with the two 2TB disks in and set it to Flex-RAID, then once it's configured those, add the 4TB disk in and it will auto-create a 2nd volume?
