The IESG has approved the following document: - 'pNFS block disk protection' (draft-ietf-nfsv4-pnfs-block-disk-protection-03.txt) as Proposed Standard This document is the product of the Network File System Version 4 Working Group. The IESG contact persons are Martin Stiemerling and Wesley Eddy. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-nfsv4-pnfs-block-disk-protection/ Technical Summary The NFSv4.1 protocol allows for the location of file system data to be expressed in the form of "layouts". The layout for a particular file identifies location and access information such that the NFSv4.1 client may "directly" access the data without interaction with the primary or NFSv4.1 meta-data server. In the instance of the pNFS block layout type (defined in RFC 5663) the client accesses data via traditional block storage protocols. The NFSv4.1 pNFS block enabled client, by definition, will have read/write access to the block devices of the NFSv4.1 server. This access presents a problem for the client operating environment in that identification of these NFSv4.1 pNFS block devices is not well defined. This I-D provides the needed identification by defining and documenting a GPT GUID value for pNFS block devices. By using this GPT GUID, the NFSv4.1 pNFS block server can now label the block devices under its control and thus eliminating the Working Group Summary The NFSv4.1 working group had immediate consensus for the need of the definition/documentation of an identifying mechanism for the pNFS block layout. Document Quality GPT GUID usage is well understood and implemented. This I-D provides a documentation/definition point. A central registration mechanism does not exist for GPT GUIDs. Given the use case of NFSv4.1 pNFS block devices, the documentation of the pNFS GPT GUID in an IETF RFC best suites the need of the community.
