安装nginx服务，需要挂载nginx-conf.d目录。报错：
Upgrading (Container should have been running but is in error state. Check logs for more information.: Failed to mount volume nginx-conf.d. Driver: rancher-nfs. Status code: 500. Status: 500 internal server error. Error Message: Failed mount -o ,nfsvers=4 111.231.145.197:/hc/data/nfs/nginx-conf.d /var/lib/rancher/volumes/rancher-nfs/nginx-conf.d)
解决办法：
vim /etc/exports
查看配置是否正确。
是否对应配置的MOUNT_DIR目录！
我就是配置错了，配置正确后存储启动成功：
