ReadyNAS Duo v2 fast flashing backup LED
Hello to all experts, Newbie on this forum, I now find myself in a desperate position and need help. Having searched the forum, I have found two threads that I have been trying to use as solutio...
StephenB,
Many thanks for your super-fast reply! :smileyhappy:
Well, I have tried tried to boot with disks installed and boot with no disks - no difference! Does not work! :smileysad:
So, it must be the chassis.
Thanks for notifying me on the risk buying used stuff - made me think that maybe the R-linux suggestion will be better in the end.
I'll buy a SATA-USB and check that the disks work... then I assume I can offload the data (old hard-disk => PC => new NAS with new hard-disk over LAN) to a new NAS via my PC using this cable?

Are you sure?
You won't be able to access the web ui w/o disks, because the OS is installed onto the disks. Also, there will still be blinking leds (telling you there are no disks). But you can ping the NAS if you can find the IP address in your router's device list, and RAIDar should be able to find it even if it's not in the router's device list.

If the data volume is still intact, R-linux will let you offload it. Personally I'd get a USB drive along with the SATA-USB, and off-load it locally. But you should be able to offload it directly to the new NAS. You might need to map the NAS network share to a drive letter.

Nope! Both disks installed.
ping = Destination host unreachable.
raidar = RAIDAR did not find a NETGEAR-storage in the network.
The backup led is flashing fast.
The disk leds are not lit at all.The DuoV2 doesn't power down with a long hold of the power button like most ReadyNAS. So that you have to remove power to re-boot is not a sign of anything wrong. While the other symptoms are, it still sounds like bad flash memory. But, the memory chip could be bad, not just the contents.
When you say a USB recovery "didn't work", what do you mean? The NAS can be quite picky about the USB drive used. So if nothing happened, it may be that you need to try another. If it appeared to work but didn't solve the problem, that's probably the chassis. Figuring out whether the recovery seems to be working is a lot easier if the USB drive has an access LED. If it just blinks briefly, then it just didn't try, either because the drive isn't compatible or because the hardware is beyond recovery.
In choosing a USB drive, older is better. Never use a USB3 device. 8GB or smaller is going to work more often. And there can be only one partition (some have a hidden one).
As for a replacement NAS, your old caddies will work in the new one, so don't let that be a constraint if you are going to trash the Duo anyway. I agree with StephenB that the Ultra2 is a step up from what you have. IMHO Netgear wasted a lot of effort on the Duo and NV+ V2's. The OS was inferior to the predecessor Intel version that runs on the Ultra (though, perhaps, a bit less daunting to the home user).
If you want to upgrade the Ultra to OS6, it is the slowest NAS that will run OS6, so I'd avoid running apps or virus protection on it. It is also best to update the RAM to 2GB. But there are still advantages to running it. Besides having a more up to date OS, you will then later be able to migrate the drives to a native OS6 device without having to go through the data recovery and transfer again, should the NAS die or you just decide to upgrade.
The DuoV1 is a huge downgrade, especially since it is limited to 2TB drives max. If you are looking for a used DuoV2, then the photo of the rear is a good place to check to make sure it really is a V2. The V1 (in all of it's iterations) has a smaller fan and a recess where the power supply connects. Compare that to the back of your unit and you'll see.
OK! Thank you!
I'll see if I can get hold on an older USB-stick and give it a second try! :- )

The disk leds are not lit at all.See what happens when you power up the NAS with both disks removed (and no USB drives connected). Some disk failures can make the NAS unbootable.
StephenB, powered up the NAS with both disks removed and various USBs connected + powered up the NAS with both disks removed and no USB connected. No difference - the backup LED continues to flash fast and the NAS does not boot :-(
Sandshark, tried five different USBs from 256MB to 8GB with the following three files loaded:
usbrecovery.v1.0.T1marvellRAIDiator-arm-5.3.13
usbrecovery.v1.0.T1marvellDuov2uImage-recovery
usbrecovery.v1.0.T1marvellinitrd-recovery.gz
No difference - the backup LED continues to flash fast and the NAS does not boot :-(
Sad as it seems - the NAS and the chassis has a hardware fault and is beyond hope...
I have in the mean time tried the R-linux with a SATA-USB cable and learned the my files and data can be found on the hard disk! :-)
So, tomorrow I'll order a new NAS with new disks... maybe I'll try another brand this time! Heard that the brand that starts with syn- and ends with -ology have good reviews! :smileyvery-happy:
To both of you - Thank you! Excellent help and ideas received! Much appreciated.
