一般的MAC电脑磁盘都不大，比如我公司的是256G，安装完rocketmq后，报磁盘空间不足，类似的错误信息见文档末尾。
百度了许久也没有找到满意的答案，有人说清理磁盘，腾出20G空间……
其实没有必要这样，只需要修改启动脚本runbroker.sh，在里面增加一句话即可：
JAVA_OPT="${JAVA_OPT} -Drocketmq.broker.diskSpaceWarningLevelRatio=0.98"
我这里把磁盘保护的百分比设置成98%，只有磁盘空间使用率达到98%时才拒绝接收producer消息。
原因如下图所示，rocketmq默认的磁盘空间警戒水位是90%，而我的MAC常年使用率在94左右，
