  • Disk synchronization
    Patent number: 10809939
    Abstract: Embodiments of the present disclosure relate to a system, a computer program product and a method for synchronizing data between a source disk and a target disk in a cluster by performing synchronization between a source disk and a target disk, the synchronization being performed while a plurality of application I/Os on a plurality of nodes in a cluster are configured to access the source disk; and wherein a coordinator and a plurality of workers in the cluster are configured to manage copying data from the source disk to the target disk.
    Type: Grant

  • Disk synchronizing
    Patent number: 9965215
    Abstract: In one aspect, a method, includes designating a range of memory in a source disk to synchronize with a target disk, receiving blocks of data that have changed in the source disk and were cloned to a target disk, marking the blocks of data as synchronized and copying data in portions of the range that are not marked as synchronized in the source disk to the target disk.

  • Disk synchronizing
    Patent number: 9007706
    Abstract: In one aspect, a method includes performing synchronization between a source disk and a target disk. The performing includes reading data, in a first read, with a first size from a source disk, writing the data from the first to a target disk, reading data, in a second read, with the first size from the source disk, determining if the data from the first read is equal to the data from the second read, reducing the first size if the data from the first read is not equal to the data in the second read and repeating the reading data in the first read, the writing, the reading data in the second read and the determining.
