Wondering if anyone has found a straight forward path to recover files off a Sparc based NAS. The DUO is dead and pulling the files off has been a PITA. Tried mounting in Ubuntu and using Linux reader from disc internals. Migrating their failed WHS info and the duo info (power surge took them both out) to a new Netgear 314. Thanks
 
1. How many drives are in the unit?
2. What is the RAID type?
3. When you cloned, did you get any read errors on any of the drives?

I know I'll probably get jumped on here for suggesting it, but this might be a good case to outsource to a data recovery professional, assuming that the data has any value at all.
 
Thanks for the response, it is a 2 drive duo in raid 1. No apparent issue with accessing the drives and using WD Diagnostics, everything is good.

The power surge took out the NIC. Netgear was no help with such an old unit. Drives are WD red 2TB.

I certainly know when to punt with mechanical drives issues. Hoping someone has ran across a straight forward process to access the files. Thanks
 
How was the original partition(s) setup? NTFS? FAT? I've had to deal with a couple of failed units in a similar situation. These were LaCie dual drive units where the onboard controller failed. As best I can tell these were setup using mdadm, the *nix software RAID utility. After using R-Studio to image the drives and other fiddling around I found that OS X picked up the RAID info and mounted them up properly. So give that a try.
 
Good thing is I don't need to worry about the raid. Should be a mirror image on each drive. The NAS uses the linux ext3 file system and 16k blocks as opposed to the standard 4k. I had some marginal success using linux reader but ran into some out of memory errors using that software. Tried reading it from osx and ubuntu with no joy.
 
Is this your drive or a client's? Here is how I would do it.

1. Clone both drives
2. Read raid meta data from the clones to determine the raid config on the data partition on each drive, this will show the raid setup and when each drive was last online
3. Rebuild the RAID virtually from the clones using the appropriate settings and software.

You may be having issues accessing the data because of LVM.

Good luck

Out of curiosity do you think that the *nix version for this SPARC device might present some undocumented features versus Intel versions of *nix.
