REPLICA IDENTIFICATION AND COLLISION AVOIDANCE IN FILE SYSTEM REPLICATION

摘要

A unique file-system node identification (ID) is created for each newly created node in a file system repository by combining a grid identification (ID), a repository identification (ID), and a node identification (ID) to form the unique file-system node ID. The unique file-system node ID is associated with a unique association identification (ID) thereby linking the node from a source repository to a target repository to form an association when performing a replication operation between the source repository and the target repository. Upon removing the association, the unique association ID is unlinked from a replication policy in a source repository, where an initiated replication operation is disabled.

1. A method for replica identification and collision avoidance in a file-system replication by using a processor device, comprising:
creating a unique file-system node identification (ID) by combining a grid identification (ID), a repository identification (ID), and a node identification (ID) for each newly created node in a file system repository; associating the unique file-system node ID with a unique association identification (ID) thereby linking the node from a source repository to a target repository to form an association when performing a replication operation between the source repository and the target repository; and upon removing the association, unlinking the unique association ID from a replication policy in a source repository, wherein an initiated replication operation is disabled.
