I have an NV+ v1 that I have started using again as a backup to my 104.
Firmware 4.1.15 T3
The problem. When I turn it on it fails at 'Booting...' the LEDs alternate between LED3 and LED1-4 which apparently means 'OS image on NAND is corrupted, please perform NAND recovery through TFTP or USB'.
However, I found just powering down with the front power button and powering on again it boots fine. But when I turn it off or it auto-shutdowns and then on again - the same thing occurs, fixed just by power cycling.
It's out of warranty. It has been upgraded with 1GB RAM (passes all 8 cycles of the inbuilt memory test) and a Noctua B9 fan.
There have been several posts here from users who started getting weird behavior with upgraded memory when they upgraded to some of the newer firmware releases.
Factory reset formats the disks causing data loss. I hope you have already backed up the data before you did the factory reset.
You may also try Skip Volume check option on the boot menu. Once you are able to log in to the admin page, check the logs. It is possible 1 disk or more have problems.
I know what a factory reset does. It didn't help anyway.
I'll try skip volume check option - is that a per boot setting or a permenant setting??
The logs don't (to me at least) indicate any problems - I have emailed them in. I have upgraded the discs to firmware CC3D as per mdgm's advice and the SMART status looks fine.
Unfortunately it's out of warranty so I doubt support would help (although tell me if i'm wrong).
It would be strange for a disk failure though for it to be so repeatable wouldn't it - whenever I turn it on from cold/autostart the first time I get the LED3 light. When I turn off and on again its fine. If I was to turn off/auto-shutdown then i'd get LED3 again.
Are there any clues in the logs I emailed in??
Is it worth trying a USB firmware flash anyway (although I think the latest version available is 4.1.12 - does this matter)??
The data on it isn't important. It's a backup of my NV+ v2 that now seems to be behaving itself. I've also just got a second hand Ultra4 that I will fill with 8TB drives in JBOD to back up the NV+ v2 and the misbehaving RN104.
I understand support charges are quite expensive, and i'm not sure what they can do that hasn't already been done - I presume I'd have to pay even if no answer is found. And given all I need to do to solve them problem really is leave it on all the time I'm not sure I can justify the cost (sorry).
I have tried a factory reset already and it didn't help. Is there anything else you can think of?? (I am picking up a spare drive tonight and will try it with just 1 in just in case it is drive related).
A failing PSU can create a lot of strange symptoms (including boot-up failures). If you are in the US you could contact the support center on that (likely would be cheaper than per-incident support). Outside the US they would likely point you to a PSU reseller, but still might be worth a try.
Or just give it up, and replace it with an RN100 series. That would be faster than the NV+, and certainly a reasonable backup choice for a duo v2. US street price for an RN102 is about $120, so that should at set a ceiling for how much time/money you should invest.
Of course there are higher-end models if you want a performance boost.
So i took a spare 2TB drive (actually one that came with my second hand Ultra4) and put it in the NV+
Boot 1: Light 3 alternating with all 4 lights - 'OS image on NAND is corrupted' - the normal error
Boot 2: as boot1 - this is unusual, normally every other boot is fine
Boot 3: Lights 1 and 2 together alternating with all 4 lights - ERR: Bad Firmware
So I put the 4 original disks back in
Boot 1: Light 3 alternating with all 4 lights - 'OS image on NAND is corrupted' - the normal error
Boot 2: Fine
Boot 3: As boot1
Boot 4: Fine
This is the normal pattern, and this is what makes me think it isn't PSU etc... it's completely predictable
So I took disc 4 out, leaving discs 1-3 of the XRAID array in.
Boot 1: Fine
Boot 2: Fine
Boot 3: Fine
So.... I thought i was on to something!!! So I put the spare 2TB disc in slot 4 - it initialised and resync'd the array last night...... then I turned it off.....
Boot 1: Light 3 alternating with all 4 lights - 'OS image on NAND is corrupted' - the normal error
Boot 1: Light 3 alternating with all 4 lights - 'OS image on NAND is corrupted' - the normal error

Boot 3: Lights 1 and 2 together alternating with all 4 lights - ERR: Bad Firmware
So I did another USB recovery with 4.1.14 - and interestingly last time I did it I got a failed... retry message on the screen before it was successfull. This time it just went through each stage without error.
3 further boots all fine.
So put original 4 discs back in.
Boot 1: Light 3 alternating with all 4 lights - 'OS image on NAND is corrupted' - the normal error
Boot 2: Kernel Panic
Boot 3: Kernal Panic
This is new!! So I pulled disc 3 of 4... and it booted. Interestingly when I then put it back in, it didn't recongise it and started a resync - so ? its bad. So i've put the spare 2TB in slot 3 and it's resyncing.
I wonder if I actually have/had 2 issues - bad disc and bad EEPROM..
I'm officially giving up! In addition have tried another different disc. Replacing other discs. Putting original 256MB memory back and doing most of the above again. Using 4.1.8, 4.1.12 and 4.1.14.
I can sometimes get it to boot 3-4 times in a row fine, but after leaving it off for a while it's always back to LED 3/1-4 flashing.
I can only assume the EEPROM is damaged, but no idea why its only every other boot that fails.
