Ready NAS NV+ (RND4425) keeps restarting
Hi All, I need help with my Ready NAS NV+, it's an old a very reliable unit that is serving me well. Though since yesterday, it keeps restarting and it finally was off when I decided to pull the ...
A PSU problem certainly can cause problems such as you are experiencing. But getting a new one to find out if that's it is risky for such an old unit. You can use a standard ATX power supply externally with an adapter cable to see if that's the problem and/or recover your data. Although the connector on the NV+ PSU is of the same type as an ATX supply, the pin-out is slightly different. So, you will need to get a 20-pin ATX extension cable and cut a couple of lines. If you find the PSU is the problem see here Inexpensive power supply replacement for legacy 4-bay Readynases for an option to replace it. You will also fnd a link to the pin-out in that thread. Replacement supplies are also available commercially, but are frankly rather expensive for resurrecting an NV+.
While there is a path to move drives from x86 based legacy systems to x86 based current ones for data recovery, there are no options for SPARC based units. But you should be able to transfer the data to a new NAS with Rsync. Even if the unit restarts in the middle, the next backup session with Rsync should start where the last one left off. So as long as it keeps being able to restart, you should eventially get to the end. Windows archive bit backup should also work so long as all the archive bits are set to start with. You could use that with a new NAS or a USB drive.
If you are not familiar with the Windows archive bit, its meaning is the opposite of what you might expect. When it is set, it means the file needs to be archived, not that it has been archived. Most Windows file operations will set it by default.
Ok, received the new power supply, installed and voilà. The NV+ is now back online (well of course it is syncing the volume). Now I'll have to figure out how to put all the cables back inside the nas (there is a lot more cables and cable length).
I also drilled some holes in the alim backplate (right under the nas fan, to allow air intake for the power supply, as this one does have a litte fan and a more traditionnal air flow : from back to front, whereas the original psu was top to top / front)
I also will set up a backup of the backup (with the usb external drive) so as to reduce downtime and also allow migration to a new NAS when the time will come.
Thank you all for your help.
Regards,
Stéphane
It is hard to get the Flex ATX PSU installed with an extension cable. The extension is helpful in dignosing the problem without messing around with the PSU, but if you make the pin swap on the supply insted of the the extension once you kow that's the fix, it will fit a lot easier. And the remaining cables can just be cut off. Shrink tubing is the best thing to use to cover the cut ends so they can't short to anything, but just stretching the insulation a bit often works as well. Tape can get messy after a while, so is best avoided.
Glad you were able to resurrect it.
The original Infrant NV supplies had that little fan, BTW.
I finally decided to not put back the PSU in the case. I have to keep the extension unit as on the PSU there is one pin that is not wired at all, and there is nothing but the plastic casing in that pin. As I do not want to spend time on this (I would have to cut the ATX connector from the PSU and solder each cable to the extension connector (also cut).
The way it is now, if the PSU ever fails again, I can change it in less that 2 sec :D
I noticed that the original PSU was missing the fan (that is there is a dedicated space for it in the PSU), they must have decided that it was too noisy and the main main was generating enough air flow to cool both disks and psu... Strange decision as I always found the NV+ extermly noisy anyway (the PSU I bought, I even wonder if the little fan is blowing as I can't hear anything from it when the NV+ fan is blowing)
What I can't figure is why do they have to not use ATX in the first place ?

The little fan on my Infrant NV does not seem to be temperature controlled, and it is quite annoyingly high pitched and loud at full speed. The one on my modified Flex ATX one is temperature controlled, and is much quieter.

They must have thought that they needed more 12V current available, and they had no need for +3.3V or -5V. They were already getting a supply without the additional connectors, so the change in pins on the retained one probably didn't add much to the cost Some drives of the time did have quite a large start-up current demand. My first NV had 4 500GB enterprise grade drives that were beasts. With more modern drives drawing less current, just cutting the 3.3 and -5 lines might be enough instead of swapping them for 12V, but I've not been willing to suggest it for permanent use.
