Changes/StratisStorage-1.0

Stratis Storage 1.0

Summary

Add support for Stratis version 1.0, a local storage management solution. This will allow further testing and user feedback that will guide Stratis's development and stabilization, and let us consider future integration into Anaconda and other more critical aspects of Fedora.

Detailed Description

Stratis is a local storage system akin to Btrfs, ZFS, and LVM. Its goal is to enable easier setup and management of disks and SSDs, as well as enabling the use of advanced storage features -- such as thin provisioning, snapshots, integrity, and a cache tier -- without requiring expert-level storage administration knowledge. Furthermore, Stratis includes monitoring and repair capabilities, and a programmatic API, for better integration with higher levels of system management software.

Benefit to Fedora

Stratis can benefit Fedora users by making it easier and less hassle to administer the system's storage devices. Making this easier is key to increasing the uptake of advanced storage features (listed above), which can further benefit the user in reduced administration headaches, increased reliability, and greater flexibility.

Down the road, integrating Stratis support into Anaconda and other management tools via its API could simplify the installation experience, and make a dnf upgrade-rollback feature much easier.

Scope

• Change owner: Stratis is currently in-development, with a 1.0 release coming soon. Stratis pre-1.0 versions are in Fedora 28 and Rawhide. Although there are clearly later opportunities for system-wide changes based on Stratis, Stratis 1.0 will be self-contained.

Upgrade/compatibility impact

Stratis 1.0 will change the on-disk metadata format, so any bleeding-edge testers of Stratis 0.5 will need to recreate pools. (The metadata format will be frozen for 1.0 so this will not be the case going forward.)

How To Test

Stratis 1.0 will be usable only for non boot or root partitions. Fedora users and testers can use Stratis on non-primary disks, and put it through its paces to generate bug reports and feature requests that can guide Stratis future development.
