Abstract
Configurations providing a non-zero threshold for verifying a root file system of an operating system stored on blocks of a boot storage are disclosed. In particular, the root file system is verified during a boot sequence for the operating system. For each block of the root file system of the boot storage, the subject technology verifies a respective block of the boot storage. A counter tracking a number of verification failures is incremented if the block fails verification. In some configurations, the subject technology determines whether the counter meets a predetermined non-zero threshold. If the counter meets the predetermined non-zero threshold, the root file system is marked as corrupted. A recovery mode for the operating system is then initiated. If the counter does not meet the predetermined non-zero threshold, the operating system is reset in order to verify the root file system during a subsequent boot sequence.
