Upgrading NV+ V2 from 4x2TB to 3x4TB
Would like to upgrade my NV+ V2 from 4x2TB to 3x4TB.
I suppose the best approach is
- full backup
- remove old disks
- install the new disks one by one and wait for resync (should be fast since disks are empty?)
- restore
Am I right?
When I remove all the disks, will the NAS need to be reinstalled like it's new or there is some guide to follow?
Thank you for your help
- Backup your data
- Verify your backup is good
- Do a Config Backup
- Power down, remove the old disks (label order). That way as a last resort you could use these disks to recover your data (not something I would rely on, but nice as a fallback in case something happens to your backup).
- Insert all the new disks
- If the disks are blank it should automatically do a factory default when you power on, otherwise you will need to do it via the boot menu
- Install any add-ons you had installed before the factory default if you still with to use them
- Restore your config backup
- Restore your data from backup
Please make sure before you start this process that you have a NV+ v2 by reading How to tell whether I have a Duo v1 or Duo v2 or NV+ v1 or NV+ v2 (the NV+ v1 supports disks up to 2TB in capacity, so it is important to confirm you have the v2).

Thank you for your so fast reply!
I have a few questions:
- I will use 3 brand new WD red 4TB disks so I suppose they will be detected as blank but, just in case, if I need to access to boot menu, do you mean this one (http://kb.netgear.com/app/answers/detail/a_id/21104)? Should I choose factory default?
- Since I will use WD red disks, should I worry about WDIDLE3 trick?
- I have some performance issue with this NAS, transfer rate is 25MB/sec (measured with nastester 1.7) via SMB. Looking at top stats while transferring file I see that smbd and m2_raid5 are eating most of the cpu. To fix this, it could be useful to skip the restore settings step and see if the stats gets better with a clean setup (even if it takes more to manually rebuild my config)? O I just reached this NAS limits?
Thanks again!

You shouldn't need to. There was a very brief period some years ago where WDC firmware used the wrong default timeout for NAS. However that was immediately fixed, and Red drive you buy now shouldn't have that issue. You can easily confirm by looking at the load cycle counts in the SMART stats.

Yes, or use the hardware manual as the guide - page 24 here: http://www.readynas.com/download/documentation/HM/ReadyNAS_Duov2_NV+v2_HW_en_19-Sept-11.pdf

If you are running 4.1.x firmware, then you have a v1. In that case, the NAS is at the performance limit (and it can't use 4 TB drives).
If you are running 5.x firmware, then your NAS should be a lot faster. It makes sense to redo the settings manually if you suspect there might be something wrong in them.
