Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] The present application provides a data verification method in a distributed storage system, and the distributed storage system may be a ceph system. Such as figure 1 As shown, in the ceph system, the file to be stored (file) can be divided into multiple objects (object), these objects can be distributed to each PG through a preset algorithm, and each PG can be distributed to each OSD middle. In this way, the objects obtained by file division can finally be stored in OSD through the organization form of PG.
[0017] In this application, in order to realize the consistency verification of some storage pools, placement groups and files in the distributed storage system, verification configuration information can be created in th...
