ReadyNAS NV+ v3 PSU Failure
Hello, After just under 5 years of faithful service (I bought it in July 2012) my ReadyNAS NV+ v3 has had a sudden PSU failure, and is no longer operable. The drive has 2x2TB WD drives instal...
Hello StephenB,
Many thanks for the prompt reply, it is greatly appreciated.
I have checked the warranty on the Netgear website (by typing in the serial number) and it appears that the warranty was only for 3 years (expired in 2015), and yes I'm the original purchaser.
I have ordered a replacement power supply online, but it is a few weeks away as it is coming from overseas, and I need to get the data accessible again as soon as possible.
Thanks for clarifying the exact model, and for detailing the steps to setup the 2nd NAS.
Two questions on this process,
- My current drives are in Slots 1 and 2 (going from the left most side), do you set the scratch drive up in Slot 3 or another slot (i.e. Slot 1) ?
- After you setup the scratch drive and upgrade the firmware, and then power down the unit, do you remove the scratch drive before installing the original drives (in their original slot order) ?
Another question, say I was deeply concerned about loosing my data and only wanted to risk one drive in the migration process (leaving the remaining drive as a last ditch recovery option via an alternate method).
- Is it possible to set up the second NAS drive as you have detailed in your reply, leave the scratch drive in place (say setup in Slot 3), and move one drive only (say the drive in Slot 1, which from memory is the 'primary' drive in the existing RAID mirror) to the new NAS drive ?
- Would the two drives sync successfully without any data loss, or would the Slot 3 drive assume it is the 'primary' drive and overwrite the migrated drive ?
Just trying to understand how the process could work if you were trying to limit the potential for data loss.
Thanks again for your assistance.

GR
On the scratch disk -
- you put the scratch disk in slot 1 with NO other drives
- after the install/firmware upgrade you power down the NAS and remove the scratch disk.
- then migrate the original disks, preserving slot order with the NAS powered down.
- Then finally power up.

No, doing that would wipe disk 1.
A newly inserted disk is ALWAYS synced to the drive(s) already installed, so anything on the newly inserted disks is wiped.
What you could do is install only disk 1, and boot up. I don't see that as safer though, since if there is a disk 1 problem when you hot-insert disk 2, you'd lose all your data.

If you only have two disks installed (XRAID or RAID-1), then one approach is to connect disk 1 to a Windows PC, and install rlinux-for-windows. That should be able to read the disk, so you can copy the data off.
Another approach is to use a disk cloning program that supports sector-by-sector copy. Clone disk 1 to a new disk, and then set disk 1 aside. When you migrate to the new NAS you can migrate the cloned disk 1+ the original disk 2.
If you don't have a backup plan in place for your NAS, I suggest taking care of that after you migrate to the new one.
Hello StephenB,
Thanks again for your prompt reply, and clarifying how the mirror process works when migrating single drives at a time.
I'll follow the instructions as per your previous posts and see how I go.
I do have a backup strategy in place, but like always, failures seem to occur out of the blue and at the worst possible time !
Thanks again for your help.

For sure.
Let us know how it works out.
Hello StephenB,
Sorry for the delayed reply, it has taken several days to get my system up and running again (all OK now), as I'll now explain.
I decided to go for the ultra conservative approach with regards to sorting my system out, in that I used the 'I cannot afford to loose any of my data at any cost' approach.
This entailed several steps in the data backup, new NAS drive setup, and disk migration.
I followed the steps you outlined in most cases, with a few additions.
The steps are below:
Preparation:
- Purcahse 2 new scratch disks (2TB Segate IronWolf)
- Purchase a Dual SATA HDD Docking Station (with one button cloning feature)
Steps:
1. I downloaded RAIDar Version 4.3.8 for Windows, and installed it on a Windows 7 Pro 64-bit machine.
2. I then downloaded and saved the lastest firmware (RAIDiator) 4.1.16.
3. I then loaded a scratch disk (2TB to match the capacity of the original disks) into the new NAS drive, in the Disk 1 slot / position.
4. I then powered up the new NAS drive and let the NAS drive format the disk.This took about 30 minutes to complete. The firmware was showing up as 4.1.10.
5. I then updated the firmware to version 4.1.16.
6. I then rebooted the NAS drive and it came up (on RAIDar) showing firmware version 4.1.16. All good.
7. While the new NAS drive was formatting the scratch disk I removed one of the exiting NAS drive disks (I chose Disk 2) and made a clone of it using the remaining (2nd) scratch disk and using the Dual STA HDD Docking Station 'one button clone' feature. By the way this took about 5 1/2 hours to complete !
8. I then shutdown the new NAS drive, and removed the newly formated scratch disk, and placed it aside for safe keeping.
9. After the cloning was completed, I migrated the original Disk 1, and the cloned Disk 2, to the new NAS drive, and powered-up the new NAS drive.
10. The new NAS drive powered up OK, and ran several checks including FS (File System), and re-syncing (Mirroring). To my surprise this process took almost 24 hours to complete !!
11. At the completion of all this the NAS drive is functioning perfectly, and it seems no data has been lost. The NAS Drive is showing 'RAID level X, Redundant', with all green indicators.
12. I checked the version of the new NAS drive on RAIDar and it is showing 4.1.10 ?!
A couple of questions;
- Any reason why the version showing up on RAIDar is showing 4.1.10 and not 4.1.16 ?
- Did I miss any steps in the process ?
- I plan to swap out the old Disk 1 for the formated scratch disk in the next week or two, so that I have two new disks in the new NAS drive. Is there any special process for doing this (or is it just a simple hot-swap, and let the NAS drive re-sync the disks) ?
Thanks again for your assistance and knowledge in how to recover from a NAS Drive unit failure.
By the way I have commenced a full back-up of the NAS drive to a portable HDD, now that the new unit is running, just to make sure :-)
Regards,
GR.
