What file system is LVM?

In short though, lvm breaks up a disk, kind of like partitions, those partitions are then formatted with a filesystem like ext4. LVM is therefore not a filesystem, it is a volume manager. The ‘pv’ in the commands stands for ‘physical volume’, the ‘vg’ for ‘volume groups’ and the ‘lv’ for ‘logical volume’.

How are logical volumes created in a LVM system?

A Logical Volume is the conceptual equivalent of a disk partition in a non-LVM system. Logical volumes are block devices which are created from the physical extents present in the same volume group. You can use command lvcreate to create a logical volume in an existing volume group. File systems are built on top of logical volumes.
