About configuring SFCFS clusters for data integrity
When a node fails, SFCFS takes corrective action and configures its components
to reflect the altered membership. If an actual node failure did not occur and if
the symptoms were identical to those of a failed node, then such a corrective
action would cause a split-brain situation.
Some scenarios that can cause such split-brain situations are as follows:
■ Broken set of private networks
If a system in a two-node cluster fails, the system stops sending heartbeats
over the private interconnects. The remaining node then takes corrective
action. The failure of the private interconnects, instead of the actual nodes,
presents identical symptoms and causes each node to determine its peer has
departed. This situation typically results in data corruption because both nodes
try to take control of data storage in an uncoordinated manner.
■ System that appears to have a system-hang
If a system is so busy that it appears to stop responding, the other nodes could
declare it as dead. This declaration may also occur for the nodes that use the
hardware that supports a "break" and "resume" function. When a node drops
