Abstract
A method for protecting page-level metadata in a storage system is provided. The method includes providing in a page table first protection data, receiving a command to read data from a page of the storage system corresponding to the page table, and comparing first protection data to second protection data. If the first protection data is different than the second protection data, then the method includes identifying third protection data in the storage system and comparing the third protection data to the first protection data. If the third protection data is different than the first protection data, then the method includes determining that the page-level metadata is inconsistent.
