Abstract: A log processing method, and a related device and system are disclosed. The method includes: obtaining a status message of a storage node cluster (S301), where the status message marks a master storage node (241) of the storage node cluster; sending a first write operation request to the master storage node (241) based on the status message (S302), so that the master storage node (241) agrees on a first write operation after agreeing on a received log with a slave storage node (242) in the storage node cluster (S304); and receiving a feedback message that is sent after the master storage node (241) agrees on the first write operation with the slave storage node (242) in the storage node cluster (S306), where the feedback message includes identification information and a response to the first write operation request, and the identification information is used to indicate the agreed log.
