Consistency method based on discarded multi-metadata server metadata log

The present invention provides a server based on multivariate data discarded metadata log consistency method, the master metadata server receives metadata request, which is saved to memory, the data from the dissemination request to the server element; from the metadata server upon receiving a request to save to memory spread, master metadata server response; master metadata server after receiving a response request submitted to the log device, after completion, to submit a request from the meta data server; submit a request is received from the metadata server, submitted to the log device, answering machine and submit the request to the application and synchronizing the disk; master metadata server receives the submitted request response, synchronized and applied to disk, discarding the command sent to the data element from the server, and save a local copy discarded according to circumstances log. By introducing three communication mechanism, so that in case of damage to the system log log device, via a small copying log files, the recovery is achieved, greatly reducing the recovery time.
