Stratis is a user-space configuration daemon that configures and monitors existing components from Linux's underlying storage components of logical volume management (LVM) and XFS filesystem via D-Bus.

## Details

Stratis is not a user-level filesystem like the Filesystem in Userspace (FUSE) system. Stratis configuration daemon was originally developed by Red Hat to have feature parity with ZFS and Btrfs. 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.[1][2] It is built upon enterprise-tested components LVM and XFS with over a decade of enterprise deployments and the lessons learned from System Storage Manager in Red Hat Enterprise Linux 7.[3]

Stratis provides ZFS/Btrfs-style features by integrating layers of existing technology: Linux's device mapper subsystem, and the XFS filesystem. The stratisd daemon manages collections of block devices, and provides a D-Bus API. The `stratis-cli` DNF package provides a command-line tool `stratis`, which itself uses the D-Bus API to communicate with `stratisd`.
