Abstract:
A multi-node data storage system comprises a first data storage system having an owner node and a backup node in a first location coupled to a second data storage system having an owner node and a backup node in a second location. Each storage system includes a copy of the same data volume. A failure of a node of the multi-node storage system is detected. An outstanding write request to the first storage system is identified. If the owner node in the first storage system fails, it is determined whether the outstanding write corresponds to a host write to the backup node of the first storage system. If so, a retransmission message is sent to the second storage system. Otherwise, the data region associated with the outstanding write request is read from the first storage system, and a resynchronization message is sent to the second storage system.

Claim (Index 15):
The system of  claim 13 , wherein the node of the multi-node data storage system is further configured to:\n write the data associated with the received write request message to the region of the data volume in the second data storage system, when there is no outstanding write request to the second data storage system that corresponds to the region of the data volume in the received message.
