Hi,
Recently disaster struck and I lost access to my 8 x 8TB disks on my DS
I'm looking for help to find the synology config files that contain:
Some detail:
- Through accident one of the 8 disktrays got ejected
What I tried to do:
I'm 98% sure that all data is still present and can be rescued.
I'm also quite sure that DiskDrill can do it, but I think I run into memory issues that cause DiskDrill to crash.
Why do I think that my data can be rescued:
- Running DiskDrill, I get a Windows Explorer style file list that reveals all the files. I can even stop DiskDrill from scanning and copy selected files to e.g. a network location.
Now to my synology conf question:
If I'm not mistaken the config information should be present on my disks.
All disks show the same partitioning:
/dev/sdb1 - linux raid - 2.37 GiB ( I think this is boot partition)
/dev/sdb2 - linux raid - 2.00 GiB (I think this is swap)
/dev/sdb3 - linux-raid - 7.27 TiB - label: DS2:3
I would like to find:
Any help or pointer will be hugely appreciated!!
Thanks for helping out!!

I'm looking for help to find the synology config files that contain:
- volume information
- SHR information
Some detail:
- Through accident one of the 8 disktrays got ejected
What I tried to do:
- connect all 8 x 8 TB drives to a PC running ubuntu, 18.04 and also 20.04.
- ran TestDisk but could not resolve the issue
- ran DiskDrill (windows version) using Windows 10
I'm 98% sure that all data is still present and can be rescued.

Now to my synology conf question:
- I don't have the correct information about my 8 disk configuration at hand.
- some research and memory suggests that I had 2 volumes, I think 1 volume consisted of 2 drives, and the second volume consisted of 6 drives.
- I think one volume was JBOD and the other SHR
If I'm not mistaken the config information should be present on my disks.
All disks show the same partitioning:
/dev/sdb1 - linux raid - 2.37 GiB ( I think this is boot partition)
/dev/sdb2 - linux raid - 2.00 GiB (I think this is swap)
/dev/sdb3 - linux-raid - 7.27 TiB - label: DS2:3
I would like to find:
- config file of JBOD volume
- config file of SHR volume
- identification of harddrive, meaning the number within the JBOD / SHR
Any help or pointer will be hugely appreciated!!

Code:
Recently disaster struck unfortunately.
I have a couple of DiskStations in my garage for local network storage, a 2 bay, 5 bay and 8 bay model.
A loose pending electrical cable to be installed, inadvertently struck on one of the drive doors and ejected the hard drive.
As a result, DiskStation signalled data lost. (Don't remember the exact terminology) and showed 8 disks present but without data.
My reasoning that this would be quite impossible, and that (most) data should be present, but maybe not immediately visible.
So I set out to search for solutions and found a Synology KB article describing how to use Ubuntu desktop to read data on DiskStation disks. I purchased a 6 sata port controller, and together with the on-board sata ports of a standard PC, I installed Ubuntu 20.04.1 to a small ssd, wired up an additional PSU, and connected the 8 drives of the 8 bay DiskStation.
I first used Gparted to have a quick look at the drives, and this shows one drive that has a problem.
I then set out to use TestDisk from Christophe Grenier, but did not continue that path as I don't fully know how to use TestDisk, and want to avoid causing more damage.
Now to my question:
I don't know the exact volume(s) configuration. From old screenshots I think that my DiskStation was configured with two volumes, one comprised out of two 8 TB disks and a second one comprised out of 6 x 8TB disks.
Since I can access my 8 hard drives using ubuntu, can I somewhere recover the volume configuration?
I know that one can make a backup of the configuration of a DiskStation, but I do not have this at hand.
See below image of Gparted.
Thanks a lot for helping out!
