Lustre 客户端挂载失败 跪求

hentai772

刚接触到Lustre，有点问题想请教一下各位高手。
在我的Lustre环境中MDS和OST都已经能正常通信，但是我在使用客户端挂载的时候MDS报错：LustreError: 120-3: Refusing connection from 192.168.20.10 for 192.168.20.30@tcp: No matching NI

按照网上的一些资料查看了/proc/sys/lnet/nis文件，发现监听的网卡都是在同一网段的，都能ping通。
[root@MDS ~]# cat /proc/sys/lnet/nis
nid                      refs peer   max    tx   min
0@lo                        3    0     0     0     0
192.168.9.203@tcp           3    8   256   256   255


[root@CLS ~]# cat /proc/sys/lnet/nis
nid                      refs peer   max    tx   min
0@lo                        2    0     0     0     0
192.168.9.201@tcp           3    8   256   256   254


防火墙和SELinux都已经关闭


客户端在mount的时候通过dmesg来查看发现：
LustreError: 11b-b: Connection to 192.168.20.30@tcp at host 192.168.20.30 on port 988 was reset: is it running a compatible version of Lustre and is 192.168.20.30@tcp one of its NIDs?

MDS上通过dmesg查看发现：
