My TS-251+ died and I need to recover data from its two HDDs. The disks were set in RAID-1 configuration.
Can I just connect and mount one disk (e.g. the first) to a linux workstation? Is it possible to do that on macOS rather than linux?
Unfortunately backups are not up-to-date, so I can't use them.
Cheers

Re: Recover data from dead TS-251+ with RAID-1
I have the same problem!
I bought new nas ts464
And I installed my old drive (two drive in raid 1)
After the system rebuild the drive
The file manager only showed the public folder!!!!

Re: Recover data from dead TS-251+ with RAID-1
My guess, you did something wrong. If you have followed the NAS migration guidelines, the system should have all shares without any manual interaction.
So yes, most likely just the shares are missing.

Re: Recover data from dead TS-251+ with RAID-1
If disks are readable at a Linux (no Mac skills here) depends to configuration. If the raid1 was a pool, you are most likely cant access the data.
If the raid1 was a static volume, chances to get access are much better. QNAP did some myteries in the LVM layer which makes it nearly impossible to access data from a pool.
Actually I did never seen a thread/post where someone reports that the could retrive the data out of such a cat2 pool configuration, but many posts claiming, that the raid could be recovered, but not the LVM structure.

Re: unknown filesystem type 'drbd'.
This is what I did on my debian linux PC:
When I connect the HDD via USB, I get the following. The disk is called /dev/sdb, and the data partition is /dev/sdb3, which is automatically assembled to /dev/md1:
/proc/mdstat confirms it's RAID-1:
Unfortunately, when I try and mount it I get the error unknown filesystem type 'drbd':
Is there anything I can do?

Re: Recover data from dead TS-251+ with RAID-1
Unfortunately QNAP uses proprietary versions of some standard Linux tools. That essentially means you cannot use standard Debian Linux to mount a RAID volume that has been QNAPized.
However you may be able to repair your TS-251. Do a search on QNAP resistor fix. If you need help with the fix let me know. I have a bunch of the required 100 ohm resistors laying around.

Re: Recover data from dead TS-251+ with RAID-1
Support suggested I use R-Linux from the following link: https://www.r-studio.com/free-linux-recovery/
I tested to recover a small folder and it seems to work.
