A distributed storage block device recovery method

The invention relates to the technical field of distributed data storage, in particular to a distributed storage block device recovery method. The method comprises the following steps: step 1, exporting metadata on each storage node; 2, classifying and archiving the metadata on each storage node according to the id of the block equipment; Step 3, copying the metadata of the same id on all the storage nodes to the same directory; and 4, merging the metadata. According to the invention, the problem of block device recovery when the distributed cluster breaks down is solved. 本发明涉及分布式数据存储技术领域，尤其是一种分布式存储块设备恢复方法。本发明的方法包括如下步骤：步骤1：导出每个存储节点上的元数据；步骤2：在每个存储节点上根据块设备的id将元数据归类存档；步骤3：将所有存储节点上同一个id的元数据拷贝至同一个目录；步骤4：将元数据进行合并。本发明解决了分布式集群故障时的块设备恢复问题。
