Abstract
Disclosed is a system and a method for reliable failover involving incomplete redundant arrays of inexpensive disks (RAID) writes in clustering systems. The system comprises the restructuring of a mirror race table (MRT) and a storage location that may be a non-volatile random access memory (NVRAM) module in a shared disk enclosure to make the MRT accessible to all nodes in the system. In one embodiment, the NVRAM module comprises copies of MRTs from each node operating within the cluster system.
