ReadyNAS NV+ v2 disk addition questions

Question

I have an NV+ v2 running a 2TB X-Raid volume over 2 2TB physical disks (so effectively RAID1).&nbsp; One of the disks is failing so I want to do a straight-swap for a new 2GB disk.&nbsp; What is the procedure for this?
&nbsp;
After that I have an additional 4TB disk that I want to add to the enclosure as a seperate volume (so it doesn't get pulled into the existing X-Raid volume).&nbsp; What is the procedure for this?
&nbsp;
Thank you!
&nbsp;

&nbsp;

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

Two issues here...
&nbsp;
First, you need to be certain that you have a v2, since the older v1 can't handle drives &gt; 2 TB.&nbsp;&nbsp;
&nbsp;
An NV+ v2 runs 5.3.x firmware.&nbsp; If you are running something else (4.1.x or 4.2.x) then you don't have a v2.&nbsp; The labels are confusing... So if you aren't running 5.3.x, then post back and tell us what you are running.
&nbsp;
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.&nbsp; If that's an issue, then expand the existing volume instead.

Hi - it's definitely a V2 (running 5.3.13).&nbsp;
&nbsp;
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).&nbsp;
&nbsp;
If I choose to go through the re-build route, what is the best way to backup the current x-raid volume.&nbsp; Can this be done directly over the USB port on the unit?

&nbsp;

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

&nbsp;

You can use the USB port, or you can back it up over the network (say to a USB drive attached to a PC).&nbsp; I don't know which is faster with the v2.&nbsp; On the v1 it's no contest - the USB performance is very poor, so backing up over the network is much faster.&nbsp; If you do back up over the network, I suggest using software that can verify.&nbsp; Teracopy is one option, there are others.
&nbsp;
Disks can fail during expansion too, so I recommend doing a backup either way.

Thanks for all your help with this.
&nbsp;
Final question for you.&nbsp; If I go down the rebuild route, what's the order of play when I bring the system back up.&nbsp; 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?

&nbsp;

In flexraid mode it shouldn't auto-create anything. When you insert the 4 TB drive, you'll have to select it and manually create the second RAID volume.
&nbsp;
That said, on the v1 NAS I've found that sometimes the system ended up with RAID-1 when I triggered FlexRAID (though I wanted jbod).
&nbsp;
But you want the 2x2TB to be RAID-1 anyway, so that's not a concern in your case.&nbsp; Still, you could start with the single 4 TB disk.&nbsp; Then add the remaining two, and create a RAID-1 volume with them. Both approaches will work.
&nbsp;
After you start the factory reset, you have a 5-10 minute window to trigger flexraid mode from RAIDar.&nbsp; You'll need to use RAIDar 4.3.8 - RAIDar 6.x doesn't work for this.
