ReadyNAS Data Recovery - VMware recovery tool
Description
This topic contains links to linux VMware images (Debian / Ubuntu) that have been modified to enable you to access your ReadyNAS duo HDDs from any machine with a USB plug and a SATA to USB cable.
Advantages:
* VMware player be downloaded freely
* Can run in both existing linux / MS Windows (XP,Vista etc) operating system without any further modification
Disadvantages:
* Requires a SATA to USB cable
* Mac users will need to find another program to run the VMware files
Background
At some point your ReadyNAS Duo unit is going to stop working (which hopefully will be long and far into in the future) and there may be a point where you'll need to rely on your external backups.
While it's a good strategy to ensure you (and your family / clients) have a good disaster recovery process (having external off-site backups, checking the backups, knowing how to restore from backups etc), in some cases the backups might not work or the backups aren't available to you.
Due to the architecture of the ReadyNAS Duo (more specifically the 16KB blocksize of the partitions), you cannot simply pull out the hard disks, place them into a standard windows / linux pc, then copy all your files across to another computer or storage device.
Unfortunately there are no windows drivers that can properly access the drives and the process to configure a linux pc is complex (see viewtopic.php?f=25&t=24861&hilit=16+blocksize for further background on this)
The following VMware images contain all required patches to read your HDDs in linux just by entering a few terminal commands.
VMplayer Link
To get started, you will need to download a version of VMplayer for your operating system Win/Linux (Mac not directly supported yet), this can be found

VMware Linux Image with Ext2Fuse
acmtn Debian release - tested ok, reports are that it works fine except for files greater than 4GB)
http://www.readynas.com/contributed/dek ... ebian5.zip
acmtn VM login info (username/password): root/rootadmin, vmuser/vmuser1
(please read the forums for more details on how to use this vmware )
_vito Ubuntu release - currently being tested, enables you to use the HDDs directly plugged into your pc without the need for a SATA to usb cable.

dekkit Debian release - tested, a number of issues.
my initial attempt that helped start this thread has been found to have quite a few issues and may not work for you, but can be found here if you would like to try:
http://www.readynas.com/contributed/dekkit/VMwareDebian5.0%20-%20ext2Fuse.rar
dekkit VM login info: User: vmplanet pass: vmplanet.net
the acmtn version at this stage appears to be getting more reliable results for users. Unfortunately, I have not had time improve on my original dekkit release due to time constraints but if you would like to try please post your results.
Dekkit release Notes:
* You will need 8GB of free disk space once you have uncompressed the image
* You will still need to execute some of the terminal commands to mount the drive (take precaution so you don't accidently blow away your data)
* This VMware can access other windows file shares and can also be configured to host windows shares (see the docs for debian for more info on this)
* To uncompress the file use WinRar: http://download.cnet.com/WinRAR-32-bit/ ... 07677.html or for non-windows platforms try: http://www.rarlab.com/download.htm
* This image is a work in progress (WIP) so please post all errrors !!!!!.
Dekkit release Usage- this may apply to the other versions (eg acmtn
Login to the OS
Access the terminal and enter the following once the HDD has been attached (take note that your /dev/c may differ):
modprobe fuse
vgscan
vgchange -ay c
mkdir /mnt/lvm
ext2fuse /dev/c/c /mnt/lvm
there is a delay in output but then ..
"/dev/c/c is to be mounted at /mnt/lvm
fuse-ext2 initialized for device: /dev/c/c
block size is 16384"
Dekkit Release Acknowledgements
The original VMware image was found http://www.vmplanet.net/node/85 (before the various patches were applied - so feel free to drop them a donation), if you can improve this image by way of a script to make it even easier to use for us 'non-linux users' then please do so and share it back with the rest of us

What RAID type did you have on your Duo?
I wonder if this would work with X-RAID?
The Duo is a 2 disk NAS so using X-RAID or RAID-1, all the data would be on disk 1. I don't think on the Duo it'd matter whether X-RAID or RAID-1 is used.
Recovery a three disk or greater X-RAID array could be more complicated.mdgm wrote:

I wasn't sure if the proprietary X-RAID format could be understood by R-Studio.mdgm wrote: Recovery a three disk or greater X-RAID array could be more complicated.
It does look a little complicated but it sounds like once you figure out the RAID parameters you can save the profile for future use.
Below is a 3 disk RAID 5 example...

So long as it can read EXT3 volumes using the 16k block size, it should be fine with using disk 1 from two disk X-RAID array.fbmachines wrote: mdgm wrote: Recovery a three disk or greater X-RAID array could be more complicated.

I guess so. If someone has used parameters to successfully recover data of a 3 or 4 disk X-RAID array it would be good if he/she could post them.mdgm wrote:

It looks like it can, so that's good news.mdgm wrote:

Agreed.- From past two weeks i've been unsuccessfully trying different things, just found this thread today and have already tried following:
1) RStudio, i've tried this recovery tool but i can't find any of my files on readynas hdd, is there specific process for it?
2) I've also tried acmtn debian vmware and have reached to stage where it says "block size is 16384" but it doesn't show anything after that. Where can i see the my readynas files/folders? Also is there a same process to mount my another usb hdd where i want to copy my readynas data? Plz help me i've zero knowledge of Linux :(

As mentioned in the earlier posts, you need to have 2 x root terminal windows open:
Terminal 1 - to mount the filestructure of the ReadyNAS drive
Terminal 2 - to navigate around the ReadyNAS filestructure and copy required files (you may need to google some basic linux commands - its similar command line in Windows)
Once you get access to your files, could you help assist the rest of the reads of this thread by taking time to document your exact steps (any screenshots would also be fantastic) - this would be great input into eventually developing a guide for new users who's lost access to their data.- Has anyone considered, or attempted to use the methods to mount nv+/duo drives on a pro, via virtual box ?
ie, take nv+ drives, put in usb cases, all drives into a usb hub, connect to pro, get an applicable VM up in virtual box on the pro, mount the x-raid array ?
I think it would be pretty awesome to see done.
even better would be getting the all the required packages running directly on the pro and mounting (via usb) the x-raid drives directly without a VM. - It would be awesome and I have thought a bit about this before, but haven't actively tried to do it. It should work as you should be able to get the VM to see the USB drives. It sounds like a good idea. I guess the challenge would be in trying to transfer the data from the disks onto the Pro without needing to send the data over the network. You would need all disks to be working fine from the X-RAID array except for the parity disk (doesn't matter if this is working fine or not).
- Hi Guys,
I need some help. I have a D-Link DNS-323 and I bought a ReadyNas DUO to replace it. I had too many troubles with D-Link and because of that I decide to switch them.
So I removed one disk from 323 and insert it into the readynas. I choose FlexRaid 0 with 500GB and left another 500GB to build a RAID 1 volume with both disks. After I copied the files from 323 to neadynas, I move the last disk to readynas.
Then my problems started. The first volume fail (not the disk), I tried to reboot, then readynas remove the partition information from the second disk and finally the readynas died. (So much luck)
So, I tried to move back the second disk into 323 but without success. I want to recover the information but until now I didn't got it. I'd tried the VMware recovery image and the R-Studio.
For VMware image, when I do the command vgscan, it find only the VG used on the VM.
For R-Studio, It finds many partition, but the files are cut and some of them didn't open. I tried to group all partition with 16k block into a virtual volume, but nothing different happens.
Please, I really need some help.
