Abstract
A caching method for a distributed storage system, a lock server node, and a lock client node is disclosed. When the lock server node receives a first lock request sent by the first lock client node for locking a first data stripe, if the lock server node determines that the first lock request is a read lock request received for the first time on the first data stripe or a write lock request on the first data stripe, the lock server node records the owner of the first data stripe is the first lock client node in recorded attribute information of data stripes, and returns to the first lock client node a first response message indicating that the owner of the first data stripe is the first lock client node, and instructing the first lock client node to cache the first data stripe.
