Cluster Coherent NFS

The Cluster Coherent NFS project

We are developing Linux kernel intefaces to allow stateful kernel lock managers such as the NFSv4 server and LOCKD to communicate with cluster file systems to enable exporting a multiple symetric NFS service. This site holds evolving design documents, issues, and references resulting code.

We currently have four areas of development.

• NFSv4 Open Share State
• NFS Byte Range Locking
• Cluster Coherent NFSv4 Delegations
• NFS Recovery and Client Migration
