从日志看异常节点的169.254.14.18:32056和169.254.17.231:19443无法使用udp进行通讯,参考:Only One Instance of a RAC Database Can Start at a Time: Second Instance Fails to Start due to “No reconfig messages from other instances” – LMON is terminating the instance (Doc ID 2528588.1),从而使得asm和db实例只能启动一个节点.到目前为止,初步看很可能是公有云的对于169.254网段的某些限制导致.
对于两个节点asm磁盘组mount,crs正常启动.这个是由于使用的是fiex asm技术实现(在asm实例启动正常情况下直接启动本地asm实例,在本地asm实例无法正常启动,通过fiex asm实现磁盘组正常mount)

    公有云那边在策略中把私网的udp限制全部放开,asm和db第二个节点也启动正常
