Records are written to a log in a storage device in a sequential order, wherein the records include a next pointer addressing a next record in a write order and a far ahead pointer addressing a far ahead record in the write order following the record. The far ahead pointer and the next pointer in a plurality of records are used to determine an end of valid log from which to start writing further records.
