In order to list all logical volumes (LVM) in Linux you can issue the below command:

$ lvscan
  ACTIVE            '/dev/mysql-vg/swap_1' [31.88 GiB] inherit
  ACTIVE            '/dev/mysql-vg/root' [27.94 GiB] inherit
  ACTIVE            '/dev/mysql-vg/var' [833.64 GiB] inherit

#linux #lvscan #lvm #logical_volume
