Stratis Storage

Summary

Add initial support for Stratis, a local storage management solution. This will allow initial testing and user feedback that will guide Stratis's development and stabilization.

Current status

  • Targeted release: Fedora 28
  • Last updated: 2017-12-13
  • Tracker bug: <will be assigned by the Wrangler>

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 0.5 release coming soon. COPR repo exists already (https://copr.fedorainfracloud.org/coprs/grover/stratis/) Additional work would be to adapt the existing packaging scripts to the new Rust library packaging support that is in F28. Early feedback in F28 will help us reach 1.0 for Fedora 29. Although there are clearly later opportunities for system-wide changes based on Stratis, this initial inclusion would be entirely self-contained.

How To Test

Until version 1.0, Stratis should not be used on a system with valuable data. Stratis will not be well-integrated into the boot process, nor will placing root partition on it be possible. However, Fedora users and testers can try Stratis on non-primary disks, and put it through its paces to generate bug reports and feature requests that can guide Stratis development leading up to a stable release.
