ABSTRACT:
A state management system preserves a state for a cluster of file servers in a cluster file system in the presence of load balancing, failover, and fail-back events. The system provides a file and record locking solution for a clustered network attached storage system running on top of a cluster file system. The system employs a lock ownership scheme in which ownership identifiers are guaranteed to be unique across clustered servers and across various protocols the clustered servers may be exporting. The system supports multi-protocol clustered NAS gateways, NAS gateway server failover and fail-back, and load-balancing architectures. The system further eliminates a need for a lock migration protocol, resulting in improved efficiency and simplicity.
