This shepherd writeup is for the following collection of I-Ds:
and is authored by Spencer Shepler - document shepherd.
(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)? Why
is this the proper type of RFC? Is this type of RFC indicated in the
title page header?
(2) The IESG approval announcement includes a Document Announcement
Write-Up. Please provide such a Document Announcement Write-Up. Recent
examples can be found in the "Action" announcements for approved
documents. The approval announcement contains the following sections:
This Internet-Draft describes NFS version 4 minor version two,
describing the protocol extensions made from NFS version 4 minor
version 1. Major extensions introduced in NFS version 4 minor
version two include: Server Side Copy, Application I/O Advise, Space
Reservations, Sparse Files, Application Data Blocks, and Labeled NFS.
Working Group Summary
The journey within the working group for this document and the
technologies that it encompasses has been a somewhat longer process
than the norm. However, the results are that many of the features
have been implemented independently and the feedback has been
effectively folded back into this document. Thus the document
quality is very good and the resultant features have been constructed
thoughfully and with working group consensus.
From the above, the process, from a time perspective, has been
longer than most but represents thoughtfulness, implementation
feedback and the results have been a high quality document.
The editing and feedback has been done by experience working
group members with input from the entire community.
Overall, I, as document shepherd and working group co-chair,
am very pleased with the results.
Document Shepherd: Spencer Shepler
Area Director: Martin Stiemerling
(3) Briefly describe the review of this document that was performed by
the Document Shepherd. If this version of the document is not ready
for publication, please explain why the document is being forwarded to
I have reviewed the document in-whole and have been involved as reviewer
throughout the process of document/protocol development.
(4) Does the document Shepherd have any concerns about the depth or
breadth of the reviews that have been performed?
I have no concerns about the breadth or depth of review.
(5) Do portions of the document need review from a particular or from
broader perspective, e.g., security, operational complexity, AAA, DNS,
DHCP, XML, or internationalization? If so, describe the review that
The area of the document that would need cross AD review (and has received
some pre-review input already) are for security. Specifically in
the areas of the Server-Side Copy feature and for the introduction
of the Labeled Security. From the I-D's security considerations section:
NFSv4.2 has all of the security concerns present in NFSv4.1 (see
Section 21 of [RFC5661]) and those present in the Server Side Copy
(see Section 4.10) and in Labeled NFS (see Section 9.7).
Note the reliance and introduction of RPCSEC_GSSv3. This document will
need to be considered along with this document for a complete review
by the IESG and broader IETF community.
As noted in the intro to the shepherding writeup, the following three
document should be coordinated for review given their dependencies.
(6) Describe any specific concerns or issues that the Document Shepherd
has with this document that the Responsible Area Director and/or the
IESG should be aware of? For example, perhaps he or she is uncomfortable
with certain parts of the document, or has concerns whether there really
is a need for it. In any event, if the WG has discussed those issues and
has indicated that it still wishes to advance the document, detail those
The document shepherd has not outstanding concerns.
(7) Has each author confirmed that any and all appropriate IPR
disclosures required for full conformance with the provisions of BCP 78
and BCP 79 have already been filed. If not, explain why.
(8) Has an IPR disclosure been filed that references this document?
If so, summarize any WG discussion and conclusion regarding the IPR
(9) How solid is the WG consensus behind this document? Does it
represent the strong concurrence of a few individuals, with others
being silent, or does the WG as a whole understand and agree with it?
There is solid working group consensus for these documents.
(10) Has anyone threatened an appeal or otherwise indicated extreme
discontent? If so, please summarise the areas of conflict in separate
email messages to the Responsible Area Director. (It should be in a
separate email because this questionnaire is publicly available.)
No, there are no known discontent with respect to these documents.
(11) Identify any ID nits the Document Shepherd has found in this
document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts
Checklist). Boilerplate checks are not enough; this check needs to be
(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type reviews.
(13) Have all references within this document been identified as
either normative or informative?
(14) Are there normative references to documents that are not ready for
advancement or are otherwise in an unclear state? If such normative
references exist, what is the plan for their completion?
Normative references are in a known/good state and ready to move forward.
(15) Are there downward normative references references (see RFC 3967)?
If so, list these downward references to support the Area Director in
the Last Call procedure.
(16) Will publication of this document change the status of any
existing RFCs? Are those RFCs listed on the title page header, listed
in the abstract, and discussed in the introduction? If the RFCs are not
listed in the Abstract and Introduction, explain why, and point to the
part of the document where the relationship of this document to the
other RFCs is discussed. If this information is not in the document,
explain why the WG considers it unnecessary.
These I-Ds/proposed standards are additive to existing work for NFSv4.
(17) Describe the Document Shepherd's review of the IANA considerations
section, especially with regard to its consistency with the body of the
document. Confirm that all protocol extensions that the document makes
are associated with the appropriate reservations in IANA registries.
Confirm that any referenced IANA registries have been clearly
identified. Confirm that newly created IANA registries include a
detailed specification of the initial contents for the registry, that
allocations procedures for future registrations are defined, and a
reasonable name for the new registry has been suggested (see RFC 5226).
IANA section is aligned with document.
(18) List any new IANA registries that require Expert Review for future
allocations. Provide any public guidance that the IESG would find
useful in selecting the IANA Experts for these new registries.
(19) Describe reviews and automated checks performed by the Document
Shepherd to validate sections of the document written in a formal
language, such as XML code, BNF rules, MIB definitions, etc.
Verified XDR provided in documents is appropriate and aligns
with XDR syntax and standards.
