mmaddnode出错？

有一个实验用的Purescale集群 on node1
现在想加一个node2
命令报错，不知该咋查
[root@node1 ~]# mmaddnode -N node2:quorum-manager
Tue Jul 21 18:02:42 EDT 2020: mmaddnode: Processing node node2
mmaddnode: Unexpected error from checkNewClusterNode node2.  Return code: 255
mmaddnode: mmaddnode quitting.  None of the specified nodes are valid.
mmaddnode: Command failed. Examine previous error messages to determine cause
