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...
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
Ok I got access to the logs, there is several synchronisation messages for volume C for a few week and messages saying that a disk present in a canal generates I/O errors and that the disk should fail shortly. How do I know which disk is labelled as "Volume C" ? And if I'm not wrong about the total capacity and that the disks are in raid-0 how am I supposed to replace the failing disk by a new one ? I'll have to mount both new and old in a pc and clone the old into the new ? Is that the way it should be done ?
Thanks

If its RAID-0, you can't replace a disk w/o cloning, since there is no raid redundancy.
Both disks are likely in volume "c" (unless it is configured as jbod).
Try running vendor diags (seatools for seagate, lifeguard for western digital) in a windows PC. Label the drives by slot, as the order likely matters.
