(2)查看是否存在/dev/zd208挂载信息

发现文件中并无此挂载信息!!!

# df -h
# cat /etc/exports
# cat /etc/fstab
(3)解决方案

创建rpcbind.service的符号链接,其实就是做个rpcbind.service的软连接用ln -s命令也行!!!

# systemctl add-wants multi-user.target rpcbind.service
Created symlink from /etc/systemd/system/multi-user.target.wants/rpcbind.service to /usr/lib/systemd/system/rpcbind. service.                                                                                 

# systemctl restart nfs-server
