  • Mechanisms for reproducing storage system metadata inconsistencies in a test environment
    Patent number: 10108537
    Abstract: Mechanisms for recreating a first inconsistency in storage system metadata encountered by an installation module during a software installation process on a first computing device are provided. A test computing device accesses on a remote storage device inconsistent storage system metadata associated with the first computing device. The inconsistent storage system metadata includes a plurality of storage system metadata segments, location information that identifies corresponding locations of the respective storage system metadata segments on at least one storage device of the first computing device, and length information that identifies corresponding lengths of the respective storage system metadata segments. For each respective storage system metadata segment of the plurality of storage system metadata segments, the respective storage system metadata segment is stored at the corresponding location on a first test storage device of a test computing device.

  • Offline debugging using a replicated operating environment
    Patent number: 9720808
    Abstract: A debugging system receives traceback data representing logging of a system error of a target system. An operating environment of the target system is replicated by creating a virtual machine (VM) having characteristics represented by the state data representing an operating state of the target system. An analysis is performed on the traceback data within the VM to simulate the system error.
