摘要： The present invention provides a lock management solution in a cluster, where the cluster includes a client and a lock server, the lock server includes an interface card and a memory, the memory stores a read lock request queue recording an identifier of a client that waits for a read lock or obtains a read lock, the memory further stores a write lock request queue recording an identifier of a client that waits for a write lock or obtains a write lock, and the memory further includes a read lock allocation count and a write lock allocation identifier, where the read lock allocation count is used to record an allocated read lock, and the write lock allocation identifier is used to indicate whether a write lock has been allocated. The client communicates with the interface card of the lock server by using the RDMA protocol to perform a lock operation.
