Abstract
Systems. Methods, and Computer Program Products are provided for recovering transactions of failed nodes using a recovery procedure in a clustered file system (CFS). A data segment is determined that the data segment should be copied to a final storage location by validating that an ownership of the data segment is not associated with any other operational node, via a distributed shared memory (DSM) agent. The ownership of the data segment is set to a local DSM agent.
