Abstract:
Provided is a method and system for redirecting data access requests in a clustered computing environment. A clustered namespace applied to the clustered computing environment includes multiple modules for storing and manipulating data. The clustered namespace is enabled by using a replicated storage location repository listing storage locations distributed throughout the clustered computing environment. When searching for data, pathnames to storage locations are examined and compared with values listed in the storage location repository to identify a storage location to visit. A module associated with an identified storage location is visited to satisfy a data access request. If a redirection identifier is encountered when examining the metadata of the identified storage location, then the storage location repository is examined to find the next storage location to visit to satisfy the data access request.
