NAS suddenly fell off the network - Case#19430473
I've tried to find a similar situation as mine, but nothing is quite the same. My NAS suddenly fell off the network this morning. One minute it was there, and the next it was gone. It seems as though it lost its IP assignment from the router and can't get a new one assigned to it. I've tried connecting direct to the device without any success. I've reset the router to factory standards without any success. I've swapped out Ethernet cables without any success. RAIDar won't see the device, and I can't browse to the device either.
After an initial soft-boot, the power LED was blinking in patterns (4 slow blinks....3 slow blinks...repeat), but now after a couple of hard-boots to test direct connectivity, it has decided to be a steady burn. The activity light does blink about every 5 seconds but no status lights on either disk. I don't know what version of firmware it was running. Honestly, the device has been sitting on the network running like a champ for nearly 2 years, so I don't remember the last time I logged into the front view to look at any settings.
Any suggestions are greatly appreciated. At this point, I am completely out of ideas.
Thanks in advance!!

- Check your purchase date, if your Duo is two years old it should still be under warranty.
The light patterns for the duo are found here: http://home.bott.ca/webserver/?p=324 Though if both blinks were slow, it doesn't quite fit.
Anyway, it sounds like you haven't checked the disk drives. So I would power down and test them in a PC with vendor tools (seatools for seagate, lifeguard for western digital).
If you have a spare SATA drive, you can try booting up the Duo with only that drive installed, and see if it initializes normally. If it does, that is a clear indication that you've lost a drive. Note this test is destructive (anything on the drive is lost). - Thanks for the quick response. I haven't tested the drives yet, as I was hoping to hear something from Netgear that would point me in that direction. However, it's been nearly 24 hours and I haven't heard anything from them :(
I feel as though I've tried everything conceivable. I even eliminated my DSL modem/router as the access point and installed an old router that I had in the basement with no success. The device just never seems to get past the boot-up stage. The fans are running at full speed as though it's waiting for the next step.
I'll give Netgear a little more time to respond and then proceed with some more diagnostics on my own. The hard thing is that even if the drives do pass Seatools diagnostics, I'm still waiting on Netgear to agree with the diagnosis and initiate a warranty repair/replacement on the hardware.
I'll keep updates posted here as they come in. - You've basically ruled out everything except the disks and the duo chassis as far as I can tell.
Did you buy the unit diskless? If so, you might as well test the drives, as you would need to replace them yourself if they failed. - I bought it with a single disk and added a second shortly after. Fortunately, if the disks did fail I recently did a back up of everything that was critical. That would make most of this data backed up in 3 different places (I learned my lesson the last time I had a drive fail).
I'll keep you posted
3 copies in different places is my threshold also. I've lost data (pre-nas) when I found I couldn't read older files backed up on a USB drive. Of course you don't find out that the backup is bad until the primary fails... Since I've raised the bar to 3 copies I haven't lost any data, though I have had some device failures.randmpark wrote: ...That would make most of this data backed up in 3 different places (I learned my lesson the last time I had a drive fail)...
My Duo lost everything after a power failure a while back, and I had to rebuild the array from scratch (and also bought my first UPS, which is another lesson learned). I've also had some individual disk failures in my Pro and my PCs. But so far, at least one copy has survived intact.- Exactly the same thing happend to my ReadyNAS Duo 2220 last evening. It suddenly went off the network and won't boot.
As with your unit my also have fans running but is stuck in the boot-up procedure, no indicators active at all except for the power indicator.
I have two HDD which were pre-installed when I purchased the unit. HDD failure seems unlikely, at least both drives at the same time, or the ReadyNAS fails to deliver in RAID 0 mode with one disk failing (or would it fail if one disk fails?). I've had no power failure so I suspect some hardware failure in the ReadyNAS unit itself.
It will be interesting to find out how to get support from Netgear on this, my hopes are not very high :(
I'll post here again if I find out what the source of failure is.
It works out better if people open their own threads (even when the symptoms are similar). Otherwise the information gets tangled up, and it is harder to respond properly.dalstrom wrote: Exactly the same thing happend to my ReadyNAS Duo 2220 last evening.

If you have 2 disks in a single raid-0 volume, then the entire volume is lost when a single disk fails. Also, HDD failures are the most common hardware problem, so even if you are not suspecting them it makes sense to rule them out early in the troubleshooting.
You can open up a support case at support.netgear.com.- I received a message from Netgear and after I asked a followup question, I quickly received a phone call from a tech who helped me diagnose the problem and determine if the NAS chassis was the issue or if it was a drive problem. Without any drives in the chassis, the NAS was able to successfully boot up. :) We installed disk one and attempted a boot-up which was unsuccessful. :( I removed disk one and successfully booted up with only disk two installed. :) I was able to download the entire log file and upload it to the case at netgear.com. The tech was quickly able to determine that disk one had a critical error that was preventing the NAS from completing the boot-up process. Because the drive came as part of the initial NAS install, it was still under warranty, so Netgear issued an RMA. :D I will ship the drive off tomorrow and wait to receive my replacement drive.
- Good, I'm glad support was able to sort it out (and that your data is all intact!)
