The IESG has received a request from the Network File System Version 4 WG

- 'Using DNS SRV to Specify a Global File Name Space with NFS version 4'
<draft-ietf-nfsv4-federated-fs-dns-srv-namespace-08.txt> as a Proposed
Standard
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@xxxxxxxx mailing lists by 2011-09-23. Exceptionally, comments may be
From Section 3:
"We propose the use of the DNS SRV resource record type [RFC2782] to
fulfill this function"
However, the IANA Considerations section says "None".
I suggest that the working group at least puts in a minimal effort in
filing the IANA book-keeping details.
"As with the AFSDB resource record type [RFC1183], the
client need only utter the (relatively) constant domain name for an
organization in order to locate its filesystem name space service."
RFC 5864 deprecates the use of the AFSDB RR to locate AFS cell
database servers.
There are a lot of SHOULDs in this draft. The following sentence in
Section 5 looks odd:
"NFS clients compliant to this standard MUST implement this
functionality."
Although draft-ietf-nfsv4-federated-fs-dns-srv-namespace-08 is
well-written, it is unclear to me why the SRV RR is not defined
according to RFC 2782.
From Section 3:
"In order to allow the NFSv4 servers so given to export a variety of
filesystems, those file servers SHOULD export the given domain's root
filesystems at "/.domainroot-{Name}" within their pseudo-filesystems,
where the "{Name}" is the name of the organization as used in the SRV
RR."
Given the normative references to STD 13, it would be better to align
the wording with DNS terms.
In Section 4.3:
"A further refinement is advisable, and SHOULD be deployed"
It is not possible to mandate deployment.
In Section 5:
"In either case, the result of the DNS lookup should be cached
(obeying TTL) so that the result could be returned more quickly
the next time."
There is some discussion in RFC 5864 and errata about TTLs.
