Authority migration request is sent to source node.
Source node can provide after lock resources control authority migration request is received according to the first entrained lock therein
The mark of source information, navigate to specific lock resource information, and the lock by each node locked in resource information for lock resource
Status information returns to destination node.
S103：The mark that first locks the source node in resource information is replaced with into the mark of destination node, and by purpose
Node for lock resource lock status information replace with source node return each node for lock resource lock status information, obtain
To the second lock resource information, and notify that the owner nodes after other node updates are purpose node, so that other nodes are to mesh
Node initiate for image file locking request when, based on second lock resource information control other nodes for image file
Access rights.
In specific implementation, when destination node receives what source node was returned according to lock resources control authority migration request
After each node is for the lock status information of the lock resource, the source node identification in resource information can be locked by first and replaced with
The mark of destination node, and each node pair that destination node is replaced with source node and returned for locking the lock status information of resource
In the lock status information of lock resource, the second lock resource information is obtained.
In addition, it is purpose node that destination node, which is also notified that the lock resources control after other node updates,.Specifically, mesh
Node can generate owner node notification instructions, and by owner nodes notification instruction to other node broadcasts, or based on each
