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 want to recover this data to the folder /home/user/backupNAS. I followed the Synology tutorial but the output of cat /proc/mdstat was this: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md2 : inactive sdb3[0](S) sdc3[2](S) sda3[1](S) 2761369344 blocks super 1.2 unused devices: <none>...
