Network storage failover systems and associated methods

A method, comprising:

• generating by a processor of a second storage node, a filtering data structure and a metadata data structure before starting a replay of entries of a log stored at a non-volatile memory of the second storage node for a failover operation initiated in response to a failure at a first storage node, the second storage node operating as a partner node of the first storage node to mirror at the non-volatile memory, one or more write requests and data associated with the one or more write requests received by the first storage node prior to the failure, wherein the filtering data structure identifies the entries, and the metadata structure stores a metadata attribute of data containers associated with the entries;
• updating by the processor, before the replay, a location data structure indicating storage locations of the non-volatile memory that store the data associated with the write requests received by the first storage node prior to the failure and mirrored at the non-volatile memory;
• and
• utilizing by the processor, the filtering data structure, the metadata structure and the location data structure for providing access to a logical storage object for processing an input/output (“I/O”) request received during the replay of the entries by the second storage node.
