=======================================================================
Technical Charter (the "Charter") for Ceph a Series of LF Projects, LLC
=======================================================================

Adopted February 12, 2026

This Charter sets forth the responsibilities and procedures for technical contribution to, and oversight of, the Ceph open source project, which has been established as Ceph a Series of LF Projects, LLC (the "Project"). LF Projects, LLC ("LF Projects") is a Delaware series limited liability company. All contributors (including committers, maintainers, and other technical positions) and other participants in the Project (collectively, "Collaborators") must comply with the terms of this Charter.

1. Mission and Scope of the Project

   a. The mission of the Project is to develop a highly scalable, open-source storage platform designed to provide unified storage for example block, object, and file systems under one platform.

   b. The scope of the Project includes collaborative development under the Project License (as defined herein) supporting the mission, including documentation, testing, integration and the creation of other artifacts that aid the development, deployment, operation or adoption of the open source project.

2. Ceph Steering Committee

   a. The Ceph Steering Committee (the "CSC") will be responsible for all technical oversight of the open source Project.

   b. The CSC voting members are initially the Project's Maintainers. At the inception of the project, the Maintainers of the Project will be as set forth within the "CONTRIBUTING" file within the Project's code repository. The CSC may choose an alternative approach for determining the voting members of the CSC, and any such alternative approach will be documented in the CONTRIBUTING file. Any meetings of the CSC are intended to be open to the public, and can be conducted electronically, via teleconference, or in person.

   c. CSC projects generally will involve Contributors and Maintainers. The CSC may adopt or modify roles so long as the roles are documented in the CONTRIBUTING file. Unless otherwise documented:

      i. Contributors include anyone in the technical community that contributes code, documentation, or other technical artifacts to the Project;

      ii. Maintainers are Contributors who have earned the ability to modify ("commit") source code, documentation or other technical artifacts in a project's repository; and

      iii. A Contributor may become a Maintainer by a majority approval of the CSC. A Maintainer may be removed by a majority approval of the CSCs.

   d. Participation in the Project through becoming a Contributor and Maintainer is open to anyone so long as they abide by the terms of this Charter.

   e. The CSC may (1) establish work flow procedures for the submission, approval, and closure/archiving of projects, (2) set requirements for the promotion of Contributors to Maintainer status, as applicable, and (3) amend, adjust, refine and/or eliminate the roles of Contributors, and Maintainer, and create new roles, and publicly document any CSC roles, as it sees fit.

   f. The CSC may elect a CSC Chair, who will preside over meetings of the CSC and will serve until their resignation, or the end of their term. In the alternative to one CSC Chair, the CSC may elect up to three co-chairs (each, a "Co-Chair") that will share the role of CSC until their respective resignation or end of term. Co-Chairs may not be all employed by a single company or group of related companies, and in the event that more than two Co-Chairs becomes employed by the same company or group of related companies ("Related Company Co-Chairs"), the CSC will decide which of the Related Company Co-Chairs will cease to serve as a Co-Chair or Co-Chairs. Term lengths for the Chair and Co-Chair positions are one year. The process for elections will be determined by the CSC and documented publicly. The CSC Chair, designated Co-Chair, or any other CSC member so designated by the CSC, will serve for a one-year term as the primary communication contact between the Project and Ceph Foundation, a directed fund of The Linux Foundation.

   g. Responsibilities: The CSC will be responsible for all aspects of oversight relating to the Project, which may include:

      i. coordinating the technical direction of the Project;

      ii. approving project or system proposals (including, but not limited to, incubation, deprecation, and changes to a sub-project's scope);

      iii. organizing sub-projects and removing sub-projects;

      iv. creating sub-committees or working groups to focus on cross-project technical issues and requirements;

      v. appointing representatives to work with other open source or open standards communities;

      vi. establishing community norms, workflows, issuing releases, and security issue reporting policies;

      vii. approving and implementing policies and processes for contributing (to be published in the CONTRIBUTING file) and coordinating with the series manager of the Project (as provided for in the Series Agreement, the "Series Manager") to resolve matters or concerns that may arise as set forth in Section 7 of this Charter;

      viii. discussions, seeking consensus, and where necessary, voting on technical matters relating to the code base that affect multiple projects; and

3. CSC Voting

   a. While the Project aims to operate as a consensus-based community, if any CSC decision requires a vote to move the Project forward, the voting members of the CSC will vote on a one vote per voting member basis.

   b. Quorum for CSC meetings requires at least fifty percent of all voting members of the CSC to be present. The CSC may continue to meet if quorum is not met but will be prevented from making any decisions at the meeting.

   c. Except as provided in Section 7.c. and 8.a, decisions by vote at a meeting require a majority vote of those in attendance, provided quorum is met. Decisions made by electronic vote without a meeting require a majority vote of all voting members of the CSC.

   d. In the event a vote cannot be resolved by the CSC, any voting member of the CSC may refer the matter to the Series Manager for assistance in reaching a resolution.

4. Compliance with Policies

   d. All Collaborators must allow open participation from any individual or organization meeting the requirements for contributing under this Charter and any policies adopted for all Collaborators by the CSC, regardless of competitive interests.

   e. The Project will operate in a transparent, open, collaborative, and ethical manner at all times.
