The hope was due to Stratis configuration daemon being in userland, it would more quickly reach maturity versus the years of kernel level development of file systems ZFS and Btrfs. [ 2 ] [ 3 ] It is built upon enterprise-tested components LVM and XFS with over a decade of enterprise deployments and the lessons learned from System Storage ...
Basic example of an LVM head Inner workings of the version 1 of LVM. In this diagram, PE stands for a Physical Extent. Typically, the first megabyte of each physical volume contains a mostly ASCII-encoded structure referred to as an "LVM header" or "LVM head". Originally, the LVM head used to be written in the first and last megabyte of each PV ...
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. NetBSD: ZFS: Yes Yes Yes Yes Yes Yes Yes
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
