I had a Synology NAS that passed away leaving me with 3 BTRFS drives in a RAID configuration that I can’t read anymore.
I followed the Synology tutorial but the output of cat /proc/mdstat was
Personalities :
md2 : inactive dm-2[2](S) dm-1[0](S) dm-0[1](S)
2761369344 blocks super 1.2
unused devices: <none>
And no output for “`. So I tried mount /dev/md2 /home/user/backupNAS -o ro which gave me this:
mount: /home/user/backupNAS : can't read superblock on /dev/md2.
Also the result of lsblk output is:
root@user-desktop:~# lsblk -o size,name,fstype,label,mountpoint
SIZE NAME FSTYPE LABEL MOUNTPOINT

I hope someone can help me. I have 1.5 TB worth of data on those drives.
