Duo V2 one disk expansion
Hi all , I have a duo V2 with 1 disk 1Tb installed in X-RAID2. I wanted to expand and bought a brand new 3Tb disk Added the new 3Tb disk to the NAS , sync started and anded after 5 hours successfu...
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).

So I had two disks, both JBOD and separate volumes both 3TB. My 2nd Volume Disk 2 died and I replaced it with a 4TB. However, the JBOD detected it ONLY as a 3TB and created a new 2.7TB volume instead of the 3.7TB.
It did NOT auto-expand from the original settings. I have the latest software and firmware.
This software is very pathetic.
We recommend sticking with the default X-RAID2. With non-redundant volumes if a disk fails and you have no backup you may lose all your data.
You could try backign up your data, doing a factory default (wipes all data, settings, everything), choose JBOD and then restore your data from backup.
The RAID is not useful because you put in 6TB and get 3TB of usable space. I don't want to pay 2x as much for the same amount of space for a backup drive. I don't need a backup of my backup.
The whole purpose of JBOD rather than a raid stripe is that if one drive failes you lose only 1 volume, not both.
JBOD is the best configuration because one drive failed but I could use my 2nd drive for months before replacing the first.
I know I can do a factory reset but then that just means that Netgear software is defective. The whole point of having a JBOD is that you shouldn't have to do a factory reset.
As as an engineer I get asked a lot for the best companies for hardware and I am so far not impressed with the limitations of Netgear at all.
The Netgear manual website says the drive will "expand" automatically so if it doesn't does this mean the NAS hardware is defective?
