To see and display information about logical volumes and attributes of a logical volume like size, read/write status, snapshot information, run:
$ sudo lvs
Sample outputs:

  LV     VG              Attr       LSize  Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  root   ubuntu-box-1-vg -wi-ao---- 37.49g                                                    
  swap_1 ubuntu-box-1-vg -wi-ao----  2.00g     

OR
$ sudo lvdisplay
Sample outputs:

  --- Logical volume ---
