Abstract
Examples include transaction management for a multi-node cluster. Some examples include generating a request log entry at an owner node that identifies a duplicate data location, tagging the duplicate data location with a requested tag, and issuing a zero-copy request that identifies the duplicate data location. In some such examples, a service node may generate a service log entry based on the zero-copy request that identifies the duplicate data location, process the zero-copy request, and tag the duplicate data location with a serviced tag. A determination may be made as to whether at least one of the owner node and the service node have failed and based on the determination that at least one has failed, the failed node may be recovered via at least one of the requested tag and the serviced tag of the duplicate data location.
