    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 reconstruction method is performed in a distributed storage system. A primary storage node in the distributed storage system performs EC encoding on to-be-written data to generate an EC stripe, and stores, on each storage node, each EC block in the EC stripe. When a fault occurs on some storage nodes and causes a write failure of EC blocks, the primary storage node locally stores an EC block allocated to a storage node to which the write fails and generates metadata information required for data reconstruction. After the storage node recovers from the fault, the primary storage node sends, to the storage node, the stored EC block allocated to the storage node to which the write fails and the metadata information corresponding to the EC block, so that the storage node that recovers from the fault completes the data reconstruction.

    Abstract: A data distribution method for improving performance of a distributed storage system includes: receiving, by a data distribution apparatus, a storage instruction of a user, dividing to-be-stored data that the storage instruction instructs to store, into P data segments, determining a storage node group corresponding to each data segment, and finally distributing the data segment to a primary node in the corresponding storage node group.

    Abstract translation: 一种用于提高分布式存储系统的性能的数据分配方法，包括：由数据分配装置将用户的存储指令，存储指令指示存储的存储数据分割成P个数据段，确定 对应于每个数据段的存储节点组，并且最后将数据段分配到相应存储节点组中的主节点。
