  • Systems and methods for maintaining data integrity during a migration
    Patent number: 7770053
    Abstract: Systems and methods are provided for maintaining data integrity in the event of device write failures during a non-disruptive migration. In one embodiment, a computer-implemented method is provided. According to the method, a filter driver in a kernel may clone an application write to both a source storage device and a target storage device. The method may detect whether the cloned application write to the source storage device or the cloned application write to target storage device failed. When the cloned application write to the source storage device or the cloned application write to target storage device failed, the method may allow application reads from only one of the source storage device and the target storage device thereafter.
