**BUG REPORT**
1. Please describe the issue you observed:
我搭建2m-2s的rocketmq集群，3个nameserver，做benchmark的时候发现slave无法同步master数据，store.log日志里一直报磁盘满的信息:

可实际上我的磁盘空间剩余90%
我去查看过源码，
DefaultMessageStore.log.info("logics disk maybe full soon, so reclaim space, "
+ logicsRatio)
===>
logics disk maybe full soon, so reclaim space, -1.0
logicsRatio == -0.1是什么意思?
- What did you do (The steps to reproduce)?
搭建2m-2s集群，3个nameserver
- What did you expect to see?
主从可以同步数据
- What did you see instead?

public static double getDiskPartitionSpaceUsedPercent(final String path) {
if (null == path || path.isEmpty())
return -1;
try {
File file = new File(path);
if (!file.exists())
return -1;
long totalSpace = file.getTotalSpace();
if (totalSpace > 0) {
long freeSpace = file.getFreeSpace();
long usedSpace = totalSpace - freeSpace;
return usedSpace / (double) totalSpace;
}
} catch (Exception e) {
return -1;
}
return -1;
}
```
Here, if filePath is null or empty or got an exception, the ratio would be -1; I would recommend use [Arthas](https://alibaba.github.io/arthas/) to make sure the filePath is valid. Then we can try to print out the Exception message here and see if it is permission related problems.
And I think this place we need to log what the exception is or record what is the cause of returning -1. If you are interested in enhance this place feel free to submit a PR.
