Check out the lvm command, more specifically (as root or with sudo):
lvm vgs
lvm lvs
lvm pvs
Using my laptop as an example (username and hostname scrubbed):
[12:07 PM] user @ laptop [~] $ sudo lvm vgs
VG #PV #LV #SN Attr VSize VFree
vg_laptop 1 3 0 wz--n- 297.89G 0
This one shows your volume groups.
[12:08 PM] user @ laptop [~] $ sudo lvm lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
lv_root vg_laptop -wi-ao 60.51G
lv_swap vg_laptop -wi-ao 5.67G
lv_vm vg_laptop -wi-ao 231.71G
This one shows the logical volumes and which volume group it is
associated with.
[12:08 PM] user @ laptop [~] $ sudo lvm pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 vg_laptop lvm2 a- 297.89G 0
And finally, this one shows where the volume group is on the disk and
what size/format it is.
