Document: draft-ietf-nfsv4-federated-fs-reqts-03
Reviewer: Pete McCann
Review Date: 2009-09-22
IETF LC End Date: 2009-09-22
IESG Telechat date: unknown
Summary: Ready, one question
Major issues: None
Minor issues:
The definition of a Replica contains the following:
Updates to replicas of the same fileset MUST appear to occur in
the same order, and therefore each replica is self-consistent at
any moment.
We do not assume that updates to each replica occur simultaneously
If a replica is offline or unreachable, the other replicas may be
updated.
However, later in the document we find this text:
N2: It is not necessary for updates and accesses to the federation
data to occur in transaction or transaction-like contexts.
Is the "federation data" just the metadata held in the NSDB, or
does it include actual file contents?
The requirement on replicas being updated in the same order seems to
imply some sort of transaction semantics among the online replicas,
no?
Nits/editorial comments:
Section 5:
replica occur simultaneously
SHOULD BE:
replica occur simultaneously.
