ReadyNAS Duo V1 - does not boot [SOLVED]
Hi all!
Please stay with my rather long description - I know it's a bit long;
In short, my Duo started to act up. It didn't start first, so after some pondering I realised that by taking out disc two it booted but still it was not normal. Admin pages or SSH wasn't accesable.
Anyway as I could get access to the files using AFP I started to move all files to a second NAS with intention of reformatting the discs and doing a factory install. While doing this after a while the Duo froze. So after a reboot I could move yet some files, it froze after some gigs, reboot and repeat ...
After several reboots I could not transfer a single file, it froze immediately.
The data share was not full, I had approx 300Gig of 2TB free. I managed to copy about 70% of the important files.
I read that it should be possible to mount the partitions directly so I took out disc two, put it in a hdd-chassis and tried to read the files directly from the disc using the application EXT2FSD but all it saw was one single partition labelled RAW. It found no way of interpreting the partition so I put the disc in the DUO-tray.
Since there might be something fishy with disc two I had a look at disc one. It had four partitions, first a EXT2 probably with the system itself (I had a look in read-only mode) then two smaller RAW partitions and a larger 1.5 TB RAW partition.
EXT2FSD could not read the RAW partitions. I boot my MacPro using a Linux Live CD and while the ext2 partition was readable the other three partitions was not even visible. I gave up the idea of reading the disc directly.
With disc one in place the DUO do not boot at all (Flashing Blue LED for 2 hours) so I reinstalled the system from firmware (Reboot button , release after 5sec flash) . The unit does not boot but flashes the blue LED. A repower did not help.
I booted from a 4.1.14 USB (power button four flashes). Still the blue LED. A repower did not help.
So I have a non-booting DUO unit, maybe a ”factory reset” will wake it but I really do not want to reformat the disc until I have as much as possible of my precious data.
I'm open to any advice here - thanks in advance!

- At this point (since the NAS is not accessible at all, and the data may be at risk), the best thing you can do is to contact support. If you are out of warranty, you can get their one-time fee or use online submission.

http://support.netgear.com/general/contact/#tab-call - Thanks - I'll contact them. Yes I'm out of warranty since maybe five years but it still is worth it.
Anyway in various posts here I found links to two other filesystem (EXT2/3/4) readers for Windows which I will try aswell. - Linux Reader works on disk 1 (http://www.diskinternals.com/linux-reader/). Disk 2 (the "parity disk") doesn't actually have a data partition (though the data is there), so you can't easily extract its data.
- The Linux Reader worked great!
I belive I understand a bit more on how the filesystem works in the DUO. The third partition on disc one holds 'links' to physical files living in the RAW partitions on disc one and two.
It takes some time though to find the folders, rescue to and then move to where they can be used.
Not all files did existed, sadly, so they could be extracted from the DUO-disc but a while lot more is saved than earlier.
I'm much happier now ;)
