About this guide

This guide describes the integration, installation and configuration of Microsoft Windows environments and SUSE Enterprise Storage using the Windows Driver.

SUSE Enterprise Storage 7.1 is an extension to SUSE Linux Enterprise Server 15 SP3. It combines the capabilities of the Ceph (http://ceph.com/) storage project with the enterprise engineering and support of SUSE. SUSE Enterprise Storage 7.1 provides IT organizations with the ability to deploy a distributed storage architecture that can support a number of use cases using commodity hardware platforms.

4 Support

Find the support statement for SUSE Enterprise Storage and general information about technology previews below. For details about the product lifecycle, see https://www.suse.com/lifecycle.

If you are entitled to support, find details on how to collect information for a support ticket at https://documentation.suse.com/sles-15/html/SLES-all/cha-adm-support.html.

4.1 Support statement for SUSE Enterprise Storage

To receive support, you need an appropriate subscription with SUSE. To view the specific support offerings available to you, go to https://www.suse.com/support/ and select your product.

The support levels are defined as follows:

L1

Problem determination, which means technical support designed to provide compatibility information, usage support, ongoing maintenance, information gathering and basic troubleshooting using available documentation.

L2

Problem isolation, which means technical support designed to analyze data, reproduce customer problems, isolate problem area and provide a resolution for problems not resolved by Level 1 or prepare for Level 3.

L3

Problem resolution, which means technical support designed to resolve problems by engaging engineering to resolve product defects which have been identified by Level 2 Support.

For contracted customers and partners, SUSE Enterprise Storage is delivered with L3 support for all packages, except for the following:

  • Technology previews.

  • Sound, graphics, fonts, and artwork.

  • Packages that require an additional customer contract.

  • Some packages shipped as part of the module Workstation Extension are L2-supported only.

  • Packages with names ending in -devel (containing header files and similar developer resources) will only be supported together with their main packages.

SUSE will only support the usage of original packages. That is, packages that are unchanged and not recompiled.

4.2 Technology previews

Technology previews are packages, stacks, or features delivered by SUSE to provide glimpses into upcoming innovations. Technology previews are included for your convenience to give you a chance to test new technologies within your environment. We would appreciate your feedback! If you test a technology preview, please contact your SUSE representative and let them know about your experience and use cases. Your input is helpful for future development.

Technology previews have the following limitations:

  • Technology previews are still in development. Therefore, they may be functionally incomplete, unstable, or in other ways not suitable for production use.

  • Technology previews are not supported.

  • Technology previews may only be available for specific hardware architectures.

  • Details and functionality of technology previews are subject to change. As a result, upgrading to subsequent releases of a technology preview may be impossible and require a fresh installation.

  • SUSE may discover that a preview does not meet customer or market needs, or does not comply with enterprise standards. Technology previews can be removed from a product at any time. SUSE does not commit to providing a supported version of such technologies in the future.

For an overview of technology previews shipped with your product, see the release notes at https://www.suse.com/releasenotes/x86_64/SUSE-Enterprise-Storage/7.1.

5 Ceph contributors

The Ceph project and its documentation is a result of the work of hundreds of contributors and organizations. See https://ceph.com/contributors/ for more details.

6 Commands and command prompts used in this guide

As a Ceph cluster administrator, you will be configuring and adjusting the cluster behavior by running specific commands. There are several types of commands you will need:

6.1 Salt-related commands

These commands help you to deploy Ceph cluster nodes, run commands on several (or all) cluster nodes at the same time, or assist you when adding or removing cluster nodes. The most frequently used commands are ceph-salt and ceph-salt config. You need to run Salt commands on the Salt Master node as root. These commands are introduced with the following prompt:

root@master # 

For example:

root@master # ceph-salt config ls

6.2 Ceph related commands

These are lower-level commands to configure and fine tune all aspects of the cluster and its gateways on the command line, for example ceph, cephadm, rbd, or radosgw-admin.

To run Ceph related commands, you need to have read access to a Ceph key. The key's capabilities then define your privileges within the Ceph environment. One option is to run Ceph commands as root (or via sudo) and use the unrestricted default keyring 'ceph.client.admin.key'.

The safer and recommended option is to create a more restrictive individual key for each administrator user and put it in a directory where the users can read it, for example:

~/.ceph/ceph.client.USERNAME.keyring
Tip
Tip: Path to Ceph keys

To use a custom admin user and keyring, you need to specify the user name and path to the key each time you run the ceph command using the -n client.USER_NAME and --keyring PATH/TO/KEYRING options.

To avoid this, include these options in the CEPH_ARGS variable in the individual users' ~/.bashrc files.

Although you can run Ceph-related commands on any cluster node, we recommend running them on the Admin Node. This documentation uses the cephuser user to run the commands, therefore they are introduced with the following prompt:

cephuser@adm > 

For example:

cephuser@adm > ceph auth list
Tip
Tip: Commands for specific nodes

If the documentation instructs you to run a command on a cluster node with a specific role, it will be addressed by the prompt. For example:

cephuser@mon > 

6.2.1 Running ceph-volume

Starting with SUSE Enterprise Storage 7, Ceph services are running containerized. If you need to run ceph-volume on an OSD node, you need to prepend it with the cephadm command, for example:

cephuser@adm > cephadm ceph-volume simple scan

6.3 General Linux commands

Linux commands not related to Ceph, such as mount, cat, or openssl, are introduced either with the cephuser@adm > or # prompts, depending on which privileges the related command requires.

6.4 Additional information

For more information on Ceph key management, refer to Section 30.2, “Key management”.
