Mount drive outside of Synology Box

How?

Synology individual drive use mdadm (raid array) filesystem, wich can be recognised to the md127 partition:

$ lsblk
sde                               8:64   0  3.7T  0 disk  
├─sde1                            8:65   0  2.4G  0 part  
├─sde2                            8:66   0    2G  0 part  
└─sde3                            8:67   0  3.6T  0 part  
  └─md127                         9:127  0  3.6T  0 raid1 
    ├─vg1-syno_vg_reserved_area 253:0    0   12M  0 lvm   
    ├─vg1-volume_1              253:1    0    2T  0 lvm   
    └─vg1-volume_2              253:2    0  1.7T  0 lvm

Mounting

Assuming volume registered itself automatically, we can get further information

$ pvscan
  PV /dev/md127   VG vg1             lvm2 [3.63 TiB / 0    free]
  Total: 1 [3.63 TiB] / in use: 1 [3.63 TiB] / in no VG: 0 [0   ]

$ lvdisplay vg1

Then we can mount vg1 volume

$ mkdir /media/syno-vg1
$ mount /dev/vg1/lv -o ro /media/syno-vg1
