Stratis 3.1.0 Release Notes

mulhern, Stratis Team

Stratis 3.1.0 includes significant improvements to the management of the thin-provisioning layers, as well as a number of other user-visible enhancements and bug fixes.

Please see this post for a detailed discussion of the thin-provisioning changes. To support these changes the Stratis CLI has been enhanced to:

• allow specifying whether or not a pool may be overprovisioned on creation
• allow changing whether or not a pool may be overprovisioned while it is running
• allow increasing the filesystem limit for a given pool
• display whether or not a pool is overprovisioned in the pool list view

Users of the Stratis CLI may also observe the following changes:

• A debug subcommand has been added to the pool, filesystem, and blockdev subcommands. Debug commands are not fully supported and may change or be removed at any time.
• The --redundancy option is no longer available when creating a pool. This option had only one permitted value so specifying it never had any effect.

stratisd 3.1.0 includes one additional user-visible change:

• The minimum size of a Stratis filesystem is increased to 512 MiB.

stratisd 3.1.0 also includes a number of internal improvements:

• The size of any newly created MDV is increased to 512 MiB.
• A pool's MDV is mounted in a private mount namespace and remains mounted while the pool is in operation.
• Improved handling of udev events on device removal.
• The usual and customary improvements to log messages.

Please consult the stratisd and stratis-cli changelogs for additional information about the 3.1.0 release.
