Overview
The document describes the process of enabling the replication of CVMFS spaces across OSG and EGI CVMFS infrastructures. The aim of this procedure is to ensure that the CVMFS replication addresses real use cases and that the VO managing the CVMFS area is supported by resource centres both in OSG and EGI.
Definitions
Please refer to the EGI Glossary for the definitions of the terms used in this procedure.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", “MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
Entities involved in the procedure
- VO representative (VOR): person who is responsible for initiating the replication process.
- OSG CVMFS Manager (OSGM): person or team who is responsible for the operations of the CVMFS services for the OSG infrastructure
- EGI CVMFS Manager (EGIM): person or team who is responsible for the operations of the CVMFS services for the EGI infrastructure
VO registration
Requirements
VO can ask to replicate the CVMFS areas used in one of the two infrastructures if they have sites supporting the VO in both EGI and OSG. The sites should already support CVMFS.
Steps
- Actions tagged VOR are the responsibility of the VO Representative.
- Actions tagged OSGM are the responsibility of the OSG CVMFS Manager.
- Actions tagged EGIM are the responsibility of the EGI CVMFS Manager.
| Responsible | Action | Prerequisites, if any | ||
|---|---|---|---|---|
| 1 | VOR | Submit CVMFS replication request The VOR opens a GGUS ticket specifying the name of the VO in EGI, and |
The VO must be supported by more than one site in EGI, the sites should already support CVMFS in the execution environment. | |
| 2 | EGIM | Validate the request The EGIM must validate the request, with the support of EGI Operations Support checking that the VO is supported in the EGI infrastructure. The result of the validation is reported in an answer to the ticket. |
