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. 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. 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. ==See also==
