    摘要: Atomic test and set (ATS) operations are carried out to perform lock operations that allow a node to acquire or release a lock to a resource of a shared file system that is stored in a data storage unit (DSU) and update its liveness information. Each ATS operation includes the step of comparing contents accessed and read through the shared file system and contents stored at a particular logical block number of the DSU. If the two contents match, updates to the contents of the lock or the liveness information are permitted.
