Claim 14:
15. A method, comprising:
allocating, by a master metadata volume node, different storage clusters contained in one or more data volumes of one or more different data volume nodes to a first file by dividing the first file between the different storage clusters;
generating and assigning, by the master metadata volume node, a sequence number to each corresponding storage cluster, each different storage cluster being associated with a different corresponding sequence number, the sequence number for a storage cluster being changed by the master metadata volume node prior to the corresponding storage cluster being reallocated;
providing, by the master metadata volume node, the assigned sequence numbers for the different storage clusters to the one or more different data volume nodes containing the different storage clusters, respectively;
receiving, by the master metadata volume node, a file access request from a client for the first file; and
providing, by the master metadata volume node, the client an identification of one or more different storage clusters allocated to the first file, 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.
