  • Methods and systems for managing corrupted meta-data in a computer system or network
    Patent number: 7818609
    Abstract: A method for managing data in a computer system comprises identifying a data-set that has data unit protection that is suspected of having been corrupted, suspending a data unit protection process for the data-set; deferring re-establishing the data unit protection process for the data-set until issuance of a request for an I/O operation for the data unit; and re-establishing the data unit protection process for the data-set in response to the request and before the I/O operation is conducted. The data has a data unit protection invalidity indicator for indicating that the data-set has data unit protection that is suspected of having been corrupted; and the data unit protection process is suspended in the presence of the data-set protection invalidity indicator. Meta-data protection that is suspected of having been corrupted may be used to identify a corrupted data-set.
