HA 同步问题，非常纠结

前几天做了一对HA，但是在verify和sync的时候不成功，卸载安装，hosts保证相同，两个node时间也做过同步但是还是不行，我尝试了将verify和sync分为两步进行，verify不成功，sync可以成功，报错如下：
WARNING: IPV6 loopback address is not present,luster.
it is recommended to have IPv6 loopback address ::1 if you are using
IPv6 only network(s) across the nodes in the cluster.
/usr/es/sbin/cluster/utilities/cldare[37]: 11600018 Memory fault(coredump)

cldare: Failures detected during verification.  Please correct
the errors and retry this command.

Verification has completed normally.

请专家帮助指点指点？
