Abstract

See full text

Various embodiments are provided for managing a global cache coherency in a distributed shared caching for a clustered file system (CFS). The CFS manages access permissions to an entire space of data segments by using the DSM module. In response to receiving a request to access one of the data segments, a calculation operation is performed for obtaining most recent contents of one of the data segments. Most recent contents are determined if ownership of the one of the data segments is possessed by a remote DSM module and the request to access one of the data segments is for shared permission and exists in the local external cache. The most recent contents are transported within the response if the response is in a remote external cache and has a valid permission for the one of the data segments otherwise reading from the one of the data segments.
