ReadyNAS NV+ v2 boot failure: could not mount root RAID


Transferred 4x WD30EFRX from the failed build of a ReadyNAS NV+ v1 into a ReadyNAS NV+ v2.


Upon boot the message appeared in the LCD console window

Err: could not mount root RAID drive

The machine was visible on RAIDar, was pingable, but there was not contactable via http.


Don’t care about the contents of the disks, they were formatted incorrectly on a ReadyNAS NV+ v1 anyway. I just need to get the ReadyNAS NV+ v2 up through a “normal” firstboot. Once it is on the air in HTTP then the HDD can be administrated.


Boot into the console (see instructions below)

  1. Normal
  2. Factory Default
  3. OS Reinstall
  4. Tech Support
  5. Skip Disk Check
  6. Memory Test
  7. Test Disks

Skipping the disk check (Selection 5) didn’t help; it still failed to boot.  Had to do Factory Default boot twice before it “took.”

To hard reset and reconfigure your RAID setup:

  1. Turn off the device.
  2. Use an unfolded paper clip to press in and hold the reset switch on the back of the unit, power it up and hold the reset button for 30 seconds while powering on the device until the Boot Menu prompt appears on the display, then remove the paperclip from the reset switch.
  3. Push the “Backup” button on the front panel to navigate through the menu to the Factory Default option.
  4. Press the reset button at the back with your paperclip to confirm the menu selection and proceed to that option.

The device will reset to the factory default settings, and wipe all the data on the drives.
