Claim 9:
10. A method, comprising:
providing, by a client computing system, a file access request to a master metadata volume node for access to a file;
receiving, by the client computing system and in response to the file access request, an identification of one or more different storage clusters allocated to the file by the master metadata volume node, and which correspond with the file access request, along with one or more sequence numbers that are associated with the one or more different storage clusters, each of the one or more different storage clusters being associated with a corresponding sequence number;
sending, by the client computing system, a data access request to a particular data volume node containing at least a first storage cluster of the one or more different storage clusters along with the corresponding associated sequence number(s); and
either, (1) receiving, by the client computing system, an indication of the data access request being granted by the particular data volume node, or
(2) receiving, by the client computing system, an indication from the particular data volume node that the data access request is denied in response to at least a first of the corresponding sequence number(s) failing to be associated with a corresponding one of the at least the first storage cluster and/or in response to a VDL (valid data length) indictor indicating data has not yet been written to the one or more storage clusters by the file.
