3 Installation and Upgrade #
3.1 Installation #
3.1.1 New RBD Image Format and Feature Defaults #
With the release of SES 3, newly created RBD images now use image-format two by default.
The exclusive-lock, object-map,
fast-diff, and deep-flatten RBD
features are disabled by default to ensure kernel RBD client
compatibility. In order to use these features, they must be explicitly
specified via " rbd create --image-feature " or in
ceph.conf with " rbd default
features ".
3.2 Upgrade-Related Notes #
This section includes upgrade-related information for this release.
3.2.1 Upgrading via Crowbar not supported #

Use the supported procedure described in Section 4.1 General Upgrade Procedure of the SES3 Administration and Deployment Guide.
3.2.2 Upgrading Requires Manually Changing the Ownership #
Upgrading from SES 2.1 requires manually changing the
ownership of the directory tree
/var/lib/ceph on each cluster
node.
For detailed upgrade instructions, see Section 4.2. Upgrade from SUSE Enterprise Storage 2.1 to 3 of the SES3 Administration and Deployment Guide.
4 Technology Previews #
Technology previews are packages, stacks, or features delivered by SUSE. These features are not supported. They may be functionally incomplete, unstable or in other ways not suitable for production use. They are mainly included for customer convenience and give customers a chance to test new technologies within an enterprise environment.
Whether a technical preview will be moved to a fully supported package later, depends on customer and market feedback. A technical preview does not automatically result in support at a later point in time. Technical previews can be dropped at any time and SUSE is not committed to providing a technical preview later in the product cycle.
Give your SUSE representative feedback, including your experience and use case.
