One embodiment is a method that divides a cluster file system into multiple segments with each segment including one or more local counters. The method then checks for inconsistencies and corrects discovered inconsistencies in each of the local counters while the file system remains online and available for use.

Managing counters in a distributed file system

One embodiment is a method that stores metadata about files separately from directories for the files in storage devices and represents the directories as a tree structure in which entries refer to separate storage blocks that include the metadata with each of the separate storage blocks storing metadata for only a single file.

Enumerating metadata in file system directories

A system and method thereof, comprising means for: communicating through at least one computer network interface with each of (i) a plurality of providers of accountable resources, and (ii) a plurality of registrars which register clients, each client having access to accountable resources of providers, and maintain client-associated accounts therewith; generating a token verifying that a client is authenticated by a registrar; logging accountable transactions identifying a client-associated account and a transaction valuation, maintained by the registrar; and periodically accounting for the logged accountable transactions between respective registrars and respective providers; wherein a valuation of the accountable transaction is dependent at least on information conveyed in the token.

System for management of alternatively priced transactions on network

A system and method are disclosed for providing multi-node environment comprising a first node associated with a first operating system; a second node associated with a second operating system, wherein the second operating system is independent of the first operating system; a storage; and an interconnect coupling the first node with the storage and coupling the second node with the storage; and wherein the first node directly accesses the storage and the second node directly accesses the storage.

System and method for a multi-node environment with shared storage

A system for managing user accounts and controlling anonymous access to resources over data networks for a plurality of provider members in a manner to preserve the secrecy of the identity of a user who is in a home provider's user/customer base. The system includes a means for sharing non-identifying user information and charges among a plurality of service provider members, including a home provider and an outside provider, a means for enabling a user who is registered as a customer with the home provider to anonymously access the resources of the outside provider, a sharing means adapted to allow the system to permit the home provider to enable access by the user to the resources of the outside provider without requiring either personal identification or an open account for the user at the outside provider, and a verification means separate from the home provider adapted to allow the outside provider to determine the user's access privileges and criteria. The verification means may include a token and authentification server. The verification means preferably does not have access to personal identification information of the user. Preferably the verification server is separate from the provider members. In another aspect, the system includes means for enabling a user who is registered as a customer with the home provider to access the resources of the outside provider, while allowing the appearance that the resources are accessed directly from the home provider.
