Abstract
Log processing provides a status message of a storage node cluster is obtained by a first node. The status message marks a master storage node of the storage node cluster. The first node can send a first write operation request to the master storage node based on the status message so that the master storage node agrees on a first write operation after agreeing on a received log with a slave storage node in the storage node cluster. The first node receives a feedback message sent after the master storage node agrees on the first write operation with the slave storage node in the storage node cluster. The feedback message includes identification information and a response to the first write operation request. The first node can send to the master storage node a target message including a current iteration identifier, and the master storage node can use the current iteration identifier to determine whether the target message is from a latest master compute node.
