Stratis 3.5.0 Release Notes

mulhern, Stratis Team

Stratis 3.5.0 includes one significant enhancement as well as several smaller improvements.

Most significantly, Stratis 3.5.0 extends its functionality to allow a user to add a cache to an encrypted pool. The cache devices are each encrypted with the same mechanism as the data devices; consequently the cache itself is encrypted.

Stratis 3.5.0 also fixes a few bugs:

• It extends the thin metadata device more eagerly, and responds to thin metadata low water mark devicemapper events. This fix was included in the stratisd 3.4.2 release.
• It makes the pool name field in the Stratis LUKS2 metadata optional; this prevents a failure to start an encrypted pool when upgrading from a previous stratisd version to stratisd 3.4.0. This fix was included in the stratisd 3.4.3 release.
• It requires a new version of the Stratis devicemapper-rs library, which contains a fix which eliminates undefined behavior in the management of ioctls with large result values. This fix was included in the stratisd 3.4.4 release.
• It requires a new version of the Stratis libblkid-rs library, which fixes a memory leak in the get_tag_value method used by stratisd. This fix is not included in any previous release.

This release also reduces the problem of repetitive log messages and modifies the D-Bus API to eliminate the redundancy parameter previously required by the CreatePool D-Bus method.

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