Diagnose Readynas Duo

Trying to start my ReadyNas Duo RND2210v2 after it probably was shut down non-gracefully (power outage). It's been stuck for 12 hours and the only LED showing is the Disc Activity LED that blinks every 5 seconds. All the other LEDs are not doing anything at all.

 

Not accessible via RAIDar. Any suggestions?

Model: RND2210v2|ReadyNAS Duo v2 2TB (2 X 1TB Desktop)

Let's start by confirming the platform/model.

 

The original Duo (called v1 here)

  • says ReadyNAS Duo on the front panel
  • runs 4.1.x firmware
  • often has labels that say v2 (and perhaps even v3)

 

The Duo v2

  • says ReadyNAS Duo v2 on the front panel
  • runs 5.3.x firmware

 

Can you let us know which version you have?

It said RND2210v2 on the bottom BUT it says ReadyNas DUO on the front and it likely runs 4.1.6.

So it's the original (called v1 here)

If you are looking at the labels, then 4.1.6 would be the firmware it shipped with.  Hopefully you updated that periodically.  The final firmware was 4.1.16.

Start by powering it down, and removing the disk(s) - labeling them by slot, so you can replace them later on.

 

The power up the NAS, and see if RAIDar finds it, and reports a "no disks" status.  The NAS uses the following LED 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.

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

 

So the NAS should also give you the "no disks detected" pattern when you do this.

 

While the disks are removed, it would be good to test them.  You need to be able to connect them to a Windows PC to do that (either with SATA or with a USB adapter/dock).  Windows won't be able to mount them, but the vendor diags will find them and can test them.  Use Seatools for Seagate disks, and either Lifeguard or WD's digital dashboard for Western Digital.  Run the full generic (non-destructive) test.

Re: Diagnose Readynas Duo

Yes, removing both disks makes RAIDar find the NAS with status "No disks detected". The web interface is not accessible. 

 

Can I remove just one of the disks to see if it's booting?

 

I have to buy something to connect the HDDs to a PC, if I find that just one of them are working - what are my options?

All that is normal (the NAS boots from the disks)

Are you running the default XRAID/RAID-1? 

Do you have a backup of your data?

 

If you are running XRAID/RAID-1, then it is possible that the NAS will boot with just disk 2 inserted (in slot 2).

Re: Diagnose Readynas Duo

If XRAID/RAID-1 is the default, then yes, probably. I've never chosen anything else, I think.

 

No backup of data (it's a NAS ffs :))

RAID is useful, but isn't enough to keep your data safe. NAS (like all storage) need to be backed up if you care about the data.

 

Hopefully we'll be able to get your data back.

Re: Diagnose Readynas Duo

Picked up on this issue now.

I bought a SATA - USB adapter, and while Seatools can't detect any hard drive - HDDScan can detect both. It seems disk 1 has many, many errors but disk 2 might be healthy.

What do you suggest I do as a next step? Is it harmless to try and start the NAS with only disk 2 inserted?

 

Edit: It seems disk 2 has no partitions according to Windows Disk Management.

If you don't have email alerts set up, you might want to take care of that after everything is up and running.  Disk errors would have resulted in you getting an email.

 


@Andy1337 wrote:

Yes, I'd try this next.  I'd put it back in bay 2 (leaving slot 1 empty).

The RAID array in the original Duo is hardware accelerated, and at least the data volume has no partition.  So I think this is normal.

Re: Diagnose Readynas Duo

Inserted disk 2 in slot 2 and it shows up in RAIDar but I can't access web interface, and I can't browse it. It shows up like this in RAIDar:

Try hovering your mouse over the various status balls - that should give you a bit more status info.

Re: Diagnose Readynas Duo

It says "RAID Level X, Not redundant. A disk failure will render this volume dead.". The first yellow dot under the disks says that disk 1 is dead (which I guess is logical, since it's not in place).

Re: Diagnose Readynas Duo

Can you ping 192.168.1.59?

 

What happens if you enter \\192.168.1.59 into the file explorer address bar?  Be careful to use the correct slash direction.

Re: Diagnose Readynas Duo

No, I can neither ping it, browse it nor access its web interface.

 

Hmm, maybe I have weird subnets honestly. The NAS used to be on 192.168.1.* network but now I moved it. Will figure out a way to fix it...

Well, it still is on a 192.168.1.x network.

 

If you changed your router address space, try changing it back temporarily.  Then change the NAS network connection to use DHCP (and optionally reserve an IP address in the router).

Re: Diagnose Readynas Duo

I fixed my network issues by connecting both my computer and the NAS to a switch and "hardcoded" my IPv4 local address to something on 192.168.1.* and then I could access it and browse it. Every file intact! 

 

Thank you so much for your help! If you ever come to Stockholm, I will buy you a nice dinner! 😉

Great.  I'd back up the files next (data is at more at risk, since one disk has failed).

I've been there a couple of times - it's a great place!  But no plans to travel right now.
