CVMFS is a scalable remote filesystem service that provides read-only access to remotely hosted filesystems. It is used in the Open Science Grid, Compute Canada, and Galaxy communities.

At present, XSEDE does not provide a service for hosting CVMFS repositories. When CvMFS is used on XSEDE resources, the repositories are hosted by Open Science Grid, Compute Canada, or the research community itself (e.g., Galaxy). Hosting a repository requires a robust IT support team, which puts it beyond the abilities of many research teams who would otherwise find CVFMS valuable in their research computing work.

This activity is to create a new XSEDE capability for hosting CVMFS repositories on behalf of research teams that use XSEDE resources. The goal is to provide a new option for research teams that would like to use CVMFS in their work: have XSEDE host the repository(ies) they use.

As a "new capability" activity, the following elements should be included in the plan:

  1. A design document explaining what the capability is, what the user experience should be, and how it will be implemented in XSEDE.
  2. A design & security review, in which important support and security issues are raised and resolved.
  3. Development of new XSEDE documentation, software packages or installers, and support processes as detailed in the design document.
  4. Additions to XSEDE's software & services registry and other information services for tracking deployment and status of the new capability.
