METHOD FOR OPERATING COMPUTER CLUSTER

摘要

PROBLEM TO BE SOLVED: To provide a method capable of coping with a fault having a potential to cause a split brain situation. SOLUTION: Specifically, safe management of a common resource is supported even if an owner of the common resource has a potential to become an object of a split brain situation. In addition, a cluster structure is allowed to be updated in spite of a fact that a part of members of a cluster can not reach during the restructuring. When all started nodes always use the latest structure as a working structure or it is impossible, it is assured that an administrator is alerted to latent inconsistency of the structure.
