This patch removes the sending node reboot in avd_sg_2n_act_susi(), or amfd will send multiple node reboot to the same node otherwise. This patch also checks the duplicated QUIESCED assignments. revision 7c6de91c653c592ad0c0d1417567a79a656d81fa Author: Minh Chau <[email protected]> Date: Wed, 3 Oct 2018 08:49:29 +1000 amf: Add new susi fsm EXCESSIVE state to handle excessive assignment due to splitbrain [#2929] Once splitbrain happens, we have multiple partitions, in which AMF will continue assignments to the spare SUs in each partitions. When network merge, these partitions join into one cluster and the assignments of SU become excessive. This patch adds a new susi fsm EXCESSIVE state, which is marked for the excessive assignments that AMF detects after multiple partitions join. For 2N SG: Any excessive assignment exists, the SU that has 2N assignment has its hosting node reboot For NWay Active, NoRed: Remove the excessive assignment only.
