Abstract
A data writing and reading method and apparatus, and a cloud storage system. The data writing method includes an access node receiving a data write request, identifying domain identification information contained in the data write request when failing to obtain an available management node, and querying a pre-saved index according to the domain identification information, wherein the index includes a correspondence between a resource pool and domain identification information, identifying a target resource pool that matches the domain identification information, each resource pool including at least one storage server, determining, from at least one storage server included in the target resource pool, one of the storage servers as a target storage server, and writing data to be written into the target storage server, to ensure that the cloud storage system operates normally without additional cost when all management nodes are at fault or the management node cluster network is abnormal.
