ReadyNAS Duo RND2110 v2 died recently. Help with recovering data from the drives
Hello, My ReadyNAS Duo v2 (2110 model) died recently. It powers up but is not responsive at all. It shows briefly as connected in my router config but then dissapears. It won't power off unless I...

If you meant my response - then that was for the x64 4.2 NAS, not the duo v1.
Here's the procedure for the 4.1 systems (like your Duo)

Mounting Sparc-based ReadyNAS Drives in x86-based Linux
(1) sudo su
(2) apt-get install fuseext2
(3) apt-get install lvm2
(4) modprobe fuse
(5) vgscan
(6) vgchange -ay c
(7) fuseext2 -o ro -o sync_read /dev/c/c /mntThat’s it!!!
You can now see the mounted files in the /mnt directoryAlternative Method
If you are trying to recover data from a Duo (or from a disk with only 1 or 2 disks in the array), then you may be able to recover the data using the following method:
- Connect your faulty disk to a Windows PC using a SATA to USB cable
- Download, install & run the free software R-linux ( https://www.r-studio.com/free-linux-recovery/ )
- Copy the recovered data from the faulty disk
The alternative method only works with the main disk (usually disk 1), not the parity disk. There is a linux version of R-Linux, which you could also try.
Note I did make some edits to the original blog post.

A lot of v1 users think they have a v2 (as the labeling is confusing). So we should start by confirming the platform.
A Duo v2
- runs 5.3.x firmware
- was introduced in 2011
- says Duo v2 on the front chassis
A Duo v1
- runs 4.1.x firmware
- was introduced in 2008
- says Duo on the front chassis
Which one do you have? There are instructions out there for mounting the Duo v1 disks in x86 linux systems, but I don't think those instructions will work with a Duo v2.
Given the partition sizes show you have a 4TB drive, you definately have a V2. I believe the instructions you can find for mounting an OS4.2.x drive in a Linux system will work for OS5.x, but I've never tried it.

The procedure for OS 4.2 should be
# vgscan # vgchange -a y # mount /dev/c/c /c
Though it would be safer to mount read-only using the -o ro option
Thank you for this! I am at work today but will try this when I get home. To test with, I will try to the read only flags first. Ultimately I will want to copy everything off of that drive but will save that until I get a new NAS setup and ready. Thanks again!

I'm not sure why it is showing 4TB because the drive is 2TB. Based on the reponse above you I have the v1. Unfortunately I can't log in to the console for it to confirm the firmware version but for now I will start down the path that I am working with older 4.x firmware. Thanks for the input!
