Method and system for transparently migrating storage objects between nodes in a clustered storage system

A computer-implemented method comprising:

• determining, by a source node servicing a storage object in a clustered storage system, a destination node is configured to service the storage object in response to a request to migrate the storage object to the destination node, wherein the verifying further comprises attempting to access the storage object and determining the storage object is accessible if the attempted access is successful;
• performing a veto check that determines whether active operations on the source node include one or more of fault tolerance, maintenance, and servicing of access requests;
• preventing, by the source node, servicing of storage requests on the storage object while ownership information of the storage object is updated to indicated the destination node in accordance with the request;
• synchronizing, by the source and destination nodes, updated ownership information to indicate ownership of the storage object by the destination node instead of the source node;
• and
• resuming, by the destination node, servicing of storage requests on the storage object at a second node based on the synchronizing.

A data processing device comprising:

• a processor coupled to a bus;
• a memory coupled to the processor through the bus;
• and
• instructions executed by the processor from the memory to cause the processor to:
• receive, at a cluster manager, a request to migrate a storage object of a first node to a second node in a clustered storage system;
• forward, to the first node, the request to migrate the storage object;
• determine, by the cluster manager, the first node is configured to migrate the storage object and the second node is configured to service the storage object, and attempt to access the storage object and determine the storage object is accessible if the attempted access is successful;
• perform a veto check that determine;
• whether active operations on the first node include one or more of fault tolerance, maintenance, and servicing of access requests;
• update ownership information of the storage object to indicate the second node instead of the first node;
• and
• prevent servicing of storage request;
• on the storage object at the first node when the second node is configured to service the storage object and for resuming servicing of storage requests on the storage object at the second node upon updating ownership information of the storage object.
