Patent ID: 7437426

Claim:
A method for handling misconfigured pointers stored on a cluster that should point to a shared-storage resource of the cluster, comprising: changing membership of a set of one or more shared-storage resources to create versions of the set; wherein the cluster includes a plurality of nodes that includes a first node; for each version of the set, generating a membership stamp that: is generated based on pointers to the one or more members of said each version, and represents the membership of said each version of the set; for each version of the set, storing in each member of said each version said each version's respective membership stamp; storing one or more pointers on the first node, said one or more pointers pointing to a certain version of the set of one or more shared-storage resources; generating a local membership stamp based on the one or more pointers, wherein said local membership reflects the membership of the certain version of the set of one or more shared-storage resource; making a comparison of the local membership stamp to the membership stamps stored in at least a portion of the certain version of the set; and making a determination of whether the one or more pointers point to all the members of the latest version of the set, said determination being based on one or more criteria, said one or more criteria being based on the comparison.
