Stratis 2.1.0 Release Notes

Stratis 2.1.0 introduces support for encryption.

It supports per-pool encryption of the devices that form a pool's data tier. A pool may be encrypted, or its constituent encrypted devices may be activated, by means of a key stored in the kernel keyring.

stratisd 2.1.0

This release implements encryption support and adds several new D-Bus interfaces to administer or monitor that support.

It implements encryption support in the following way:

stratisd 2.1.0 supplies several new D-Bus interfaces:

Please consult the D-Bus API Reference for the precise D-Bus specification.

The following are significant implementation details:

We would like to thank our external contributor GuillaumeGomez for further work on metadata refactoring (stratisd issue 1573).

stratis-cli 2.1.0

This release requires stratisd 2.1.0. The user will observe the following changes:

All commands now verify that stratis is communicating with a compatible version of stratisd and will fail with an appropriate error if stratisd is found to have an incompatible version.

Usage

To create an encrypted pool, a user must first ensure that a key is placed in the kernel keyring. We strongly encourage using the commands available via the stratis key subcommand for this task. This key, which is secret, has a corresponding key description, which is public.

An encrypted pool is then created by specifying the key description when using the pool create command.

It is necessary that the correct key and corresponding key description be set in the kernel keyring in order to set up a previously encrypted pool. Setting up a previously encrypted pool requires an explicit pool unlock command from the user. This command will attempt to unlock the devices belonging to any previously encrypted pool; it can only unlock all devices if a key for every encrypted pool is in the keyring. Once the devices belonging to a previously encrypted pool have been unlocked, the pool will be set up, and can be used in exactly the same manner as an unencrypted pool.

Please consult the changelogs for additional information about the release.
