Abstract
Apparatus and method are disclosed for managing lock state information in a distributed file system. A set of data containers storing data is maintained. The data containers are striped across a plurality of volumes, where each volume includes one or more data storage devices. A metadata volume is maintained with the plurality of volumes, the metadata volume configured to include a lock state database that stores lock state information for the plurality of volumes. The lock state information is communicated between the metadata volume and the plurality of volumes.
