ACK Christine Caulfield napsal(a):
auto_tie_breaker can behave incorrectly in the case of a cluster with an odd number of nodes. It's possible for a partition to have quorum while the other side has the ATB node, and both will continue working. (Of course in a properly configured cluster one side will be fenced but that becomes an indeterminate race .. just what ATB is supposed to avoid). This patch prevents ATB from running in a partition if the 'other' partition might have quorum, and also mandates the use of wait_for_all in clusters with an odd number of nodes so that a quorate partition cannot start services or fence an existing partition with the tie breaker node.
