Abstract
A distributed storage and replication system includes a MDC module, multiple IO routing modules, and multiple OSD nodes. The MDC module is adapted to configure at least two partition, the IO routing module is adapted to route an IO request to an OSD node, and the OSD node is adapted to execute storage of data corresponding to the IO request. The MDC is configured to determine a faulty OSD node, update a partition view of a partition group that includes a partition on the faulty OSD node, and send an updating notification to a primary OSD node in the updated partition view. The primary OSD node is adapted to process replication of the data corresponding to the IO request. According to embodiments of the present disclosure, processing performance, fault tolerance, and availability of consistency replication are improved.
