两台主机 搭建 keepalived 高可用的 NFS 系统，其他主机访问 keepalived 高可用的虚拟节点，
当其中一个 NFS 主机宕机后，虚拟节点漂移到另一个主机，
其他主机访问报错：

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:8m8cEBrpWN1BPty3VLwlRQBahTfJneSiJeagIn5N+pI.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:11
ECDSA host key for [192.168.1.110]:22 has changed and you have requested strict checking.
Host key verification failed.
