ReadyNAS DUO unreachable and doesn't seem to boot anymore
Hi all, I tried to troubleshoot the problem using this guide : http://www.readynas.com/download/documentation/support/ReadyNAS-LED.pdf but I don't understand which LED of the NAS correspond to th...
Does it match any of these codes?
LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by an 1s delay, followed by a number of slow blinks. The number of slow blinks will be the error code.Try installing linux reader on a windows PC ( http://www.diskinternals.com/linux-reader/ ), and see if it can find content on disk 1. Its fine to connect that disk to the PC with a USB adapter.
Current error codes:
1 - Vendor mismatch
2 - No disks detected
3 - Bad contents on root partition of disks
4 - Flash error
5 - Unsupported RAID configuration
It is important not to remove/insert your disks into the NAS with the NAS powered up (the NAS could wipe the data on reinsertion). And you should lable the drives by slot number before removing them.
While in the PC you should test the drive with vendor diags (seatools for seagate, lifeguard for western digital).
Hi,
Thanks for your answer.
I don't think I've seen such a pattern when powering up. As I mentioned, I've never seen the "backup" led light on since the problem occurred.
I'll check that as soon as I can get back to the NAS and if no error code is matched I'll try to retrieve the data to another disk (probably in a few days).
Hi,
I tried again to boot the NAS, the power led blinked fast and then began pulsating while the ACT led was blinking all along.
At the end I have the power LED pulsating, both LED for disks ON and nothing else aside from the ACT blinking fast sometimes.
Still answers to PING but the web interface is not accessible,a shame since it could be a powerful debugging tool but could mean that the OS doesn't start properly which lead me to think that the disks are okay, while the network interface still boots properly.
I'll try to open up the NAS to get to the disks and see if I can retrieve the data. In any case, does it mean that there is no way to get the NAS working again ?
The led codes are so useless that I can't even figure out if the solution is simple like changing the SODIMM memory. It seems that the NAS was quite clogged with dust which might have led to a overheat.
Thanks for your help.
Hi again,
I plugged the disk 1 into the computer, windows sees the partitions but I can't access to it (seems windows cannot mount this format by itself).
One thing that surprised me when I took a look at the disk is that it is a 2TB and the NAS has 4TB of storage which makes me think that the disks are mounted in RAID-0 (which is totally weird for a backup device, I don't understand why the guy who configured it made it that way).
So I guessed the disks are ok since I could see the partitions but I'm not very confident in trying to plug the two disks into a pc so that I can mount them in RAID-0 so I put it back in the NAS and reboot it.
Now I see the NAS in the network, and can access the web interface, which is a very surprising to happen now but the web interface is really slow, I didn't manage to access the logs yet (a warning appeared at login saying to check the logs for errors).
I was told that sometimes the NAS takes a very long time to boot because it is upgrading, how can I know this is happening ?
More questions to come soon if someone is available to help me out.
Thanks.
The codes I posted only apply after the bios POST passes, so it is quite possible that there is a system board or memory failure.
There are two very different duo models - so we do need to sort which you have. There's a guide here: http://www.rnasguide.com/2012/01/09/how-to-tell-whether-i-have-a-duo-v1-or-duo-v2-or-nv-v1-or-nv-v2/
Odds are that you have a v1 (simply because it was in production longer).
Assuming that is the case: Window certainly can't read the disk format. If this were the default XRAID you could get the data from the data disk from windows with linux reader. ( http://www.diskinternals.com/linux-reader/using linux reader )
If it is raid-0 you can mount it from an x86 linux system, there is a guide here you could try: http://jim-st.blogspot.com/2012/07/mouning-readynas-drives-on-x86-systems.html
