Run sudo lvs to list logical volumes and sudo vgs to see volume groups with total and free space.

01Command

Command

$ sudo lvs && sudo vgs

02What it does

LVM sits between your disks and filesystems: physical volumes form volume groups, from which logical volumes are carved. lvs shows each LV's size, its VG and attributes (the 'a' flag means active, 'w' writable), while vgs summarizes VG capacity with VFree telling you how much room is left to grow. Add -v for per-device detail or use pvs for the physical-volume layer — the three reports together map the whole storage stack.

!Warning: These commands are read-only reports; but resizing or removing LVs later is destructive — always confirm the exact LV name before lvremove or lvreduce.
