A method and system for recovering mirrored logical data volumes within a computer system after a system failure is disclosed. A computer system includes mirrored logical volumes that can be accessed by multiple nodes. Mirrored in-flight logs are provided for the mirrored logical volumes. The mirrored in-flight logs include multiple node partitions, each node partition corresponding to one of the nodes. Furthermore, each entry within the mirrored in-flight logs indicate whether or not a write operation is currently being performed by at least one of the nodes. After an abnormal termination of one of the nodes due to, for example, a system failure, one of the remaining nodes is automatically selected to copy data from one of the mirrored logical volumes to another of the mirrored logical volumes, according to the entries within one of the mirrored in-flight logs.
