摘要： A computer-implemented method for natural batching of I/O operations on a replication log may include: 1) identifying a replication log that records the order of writes within a cluster replication system, 2) determining that the replication log is unavailable, 3) queuing incoming I/O operations for the replication log in a single batch while the replication log is unavailable, 4) determining that the replication log has become available, 5) ceasing queuing of incoming I/O operations for the replication log based on the determination that the replication log has become available, and 6) grouping a plurality of I/O operations in the single batch for processing in parallel by assigning a same generation number to the plurality of I/O operations. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A computer-implemented method for shipping I/O operations to prevent replication failure may include 1) attempting to perform an I/O operation in a system configured to replicate data from a data cluster to another data cluster, 2) detecting a failure in at least part of the attempt to perform the I/O operation that threatens to fail the system's replication of data from the data cluster to the other data cluster, and, in response to detecting the failure, 3) shipping the I/O operation from a node originally responsible for servicing the I/O operation to another node to complete the I/O operation without failing the system's replication of data from the data cluster to the other data cluster. Various other methods, systems, and computer-readable media are also disclosed.
