Abstract: Methods and a processing system directed to a file system checker are described. A file system checker performs file system validation by validating a file system's nodes. Each node is associated with two kinds of data: metadata and referenced data. A file system checker may validate one node at a time or a group of nodes contemporaneously (e.g., in parallel). The file system checker uses a dual phase procedure. The first phase includes validating metadata. The second phase includes validating, as appropriate, node type or link count. Dual phase file system checking allows validation of a node without validating referenced data associated with downstream nodes. Where validation of a given node requires validating a downstream node, performing a first phase test on the downstream node is sufficient to validate the given node. Upon completion, the given node may be unlocked for access by external devices and users.

Abstract: A system to synchronize a database and a non-database resource includes an application to transmit a request to a service provider to perform an action. The service provider receives the request and performs the action, the action not being under commit coordination. The service provider further inserts an entry into an action-reversal table to reverse the action and makes the insertion permanent.
