Title:
データ利用についてのマウント時間の調停
Document Type and Number:
Japanese Patent JP5636034
Kind Code:
B2
Abstract:
Systems and methods are disclosed for mount-time reconciliation of data availability. During system boot-up, a non-volatile memory ("NVM") driver (212) can be enumerated, and an NVM driver mapping (402) can be obtained. The NVM driver mapping (402) can include the actual availability of LBAs in the NVM (120,220). A file system (210) can then be mounted, and a file system allocation state can be generated. The file system allocation state can indicate the file system's view of the availability of LBAs. Subsequently, data availability reconciliation can be performed. That is, the file system allocation state and the NVM driver mapping (402) can be overlaid and compared with one another in order to expose any discrepancies.
