Video server and rebuild processing control method

摘要

A video server has a table generator, a rebuild processor, and a rebuild controller. The table generator generates a management table of content data ID that specifies the content data and the write location of the content data in the storage unit where the content data are recorded. When a problem takes place in at least one of the storage devices, the rebuild processor executes a rebuild process to recover the content data of the troubled storage device. When a rebuild start request is generated by the rebuild processor, the rebuild controller controls the start and stop of the rebuild process by referring to the management table.

主权项

1. A content server having a storage unit that comprises:
a plurality of storage devices to which content data are to be written; a management table generator configured to generate a management table that records storage addresses for the content data and a state of writing the content data at the storage addresses; and a control unit configured to access the management table and control a rebuild operation for rebuilding the content data written to the storage devices based on the management table when one of the storage devices becomes damaged or troubled, wherein the control unit initiates the rebuild operation prior to writing all of the content data; wherein the control unit references the management table during the rebuild operation to rebuild the content data that are already written to the storage devices and are in the process of being written to the storage devices, but not the content data for which writing has not been initiated.
