Computer-readable recording medium, data management method, and storage device

摘要

An internode put requesting unit detects a time-out with respect to a put request issued to the next node in the order of a multiplexing chain and notifies a put/get executing unit of the time-out. The put/get executing unit sends an error to the previous node in the order of the multiplexing chain or a client and instructs a put-failed-data synchronizing unit to synchronize data failed to be put, and the put-failed-data synchronizing unit performs a synchronization process. A primary makes other put requests wait until completion of the synchronization process. Furthermore, when having received the error, the client issues a get request to the tail end of the multiplexing chain.

1. A non-transitory computer-readable recording medium having stored therein a data management program, the data management program causing a computer functioning as a storage device storing therein the same data as other storage devices to execute a process comprising:
accepting a request to write update data of the data from either a first device, one of the other storage devices storing therein the data, or a client device; requesting a second device, one of the other storage devices storing therein the data other than the first device, to write the update data thereon; notifying the first device or client device that has requested to write the update data of writing failed due to failure occurrence when there is no reply from the second device within a predetermined time frame or when having notified of writing failed due to failure occurrence by the second device; synchronizing the data among the other storage devices storing therein the data; and returning, until completion of the synchronization of the data, an error requesting for retry on a read request.
