rocketMQ系列（8） 解决rocketmq发送消息报错： service not available now, maybe disk full

com.alibaba.rocketmq.client.exception.MQBrokerException: CODE: 14 DESC: service not available now, maybe disk full, CL: 0.87 CQ: 0.87 INDEX: 0.87, maybe your broker machine memory too small.

问题分析与解决

rocketmq源码的DefaultMessageStore类里，默认会把剩余磁盘的比率不足75%(rocketmq版本不同这个比率好像不一样)当做磁盘空间不足处理

既然磁盘空间不够，那就配置一下，把默认磁盘比率放大一些

conf 下brocker 配置文件
在最后加一行diskMaxUsedSpaceRatio=99(所有节点的配置文件都加一下)，表示剩余磁盘比例不足99才报错

重启mq

以上步骤操作完成后，再尝试发送消息：
