Abstract: A data storage method is used to improve storage consistency of a distributed storage system. The method includes: a primary storage node performs EC coding on a to-be-stored data segment to obtain a target EC stripe; determines in a storage node group to which the primary storage node belongs, m+k target storage nodes used to store m+k target EC blocks of the target EC stripe; sends a preparation message to the target storage nodes; receives a response message sent by a target storage node; and sends an execution message to the target storage nodes to instruct the target storage nodes to write target EC blocks that are in preparation logs.

Abstract: A data recovery method to improve storage consistency of a distributed storage system includes: receiving a recovery message from a storage node after a fault recovery of the faulty storage node; obtaining N lost erasure coding (EC) blocks of the faulty storage node through computation according to EC blocks stored by non-faulty storage nodes; sequentially sending N lost EC blocks to the faulty storage node for storage. In the process of sequentially sending the N lost EC blocks to the faulty storage node, when it is determined that for a first EC block that is to be stored by the faulty storage node, a second EC block having a same key value as the first EC block exists in the lost EC blocks, after the faulty storage node stores the second EC block, the first EC block is sent to the faulty storage node to store.

Abstract: A data processing method in a storage system and the storage system, and relates to the field of data storage technologies. A client first sends a data block in a stripe and metadata of the data block to a data storage node. The client then sends the metadata of the data block and a parity block to a parity storage node, to back up the metadata of the data block on the parity storage node. When the metadata of the data block is successfully backed up, the data block is written into a corresponding storage device based on a storage location indicated by the metadata. This reduces write operation time.

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.
