| Refers to PEs as PPs (physical partitions), and to LEs as LPs (logical partitions). Does not have a copy-on-write snapshot mechanism; creates snapshots by freezing one volume of a mirror pair.

| NetBSD from version 6.0 supports its own re-implementation of Linux LVM. Re-implementation is based on a BSD licensed device-mapper driver and uses a port of Linux lvm tools as the userspace part of LVM.  There is no need to support RAID5 in LVM because of NetBSD superior RAIDFrame subsystem.
