HDFS space quota exception

[hehaore...@gmail.com]

hello HDFS cluster version 2.7.2, I set a space quota for the directory, but the available space is much less than expected, for example, this image has a quota of 600T, 31T used space, it should be 500T free space, but it actually shows only 132T. I randomly checked the number of file copies in the directory, and found that they were all 3. May I ask what caused this problem? I checked the patch of the community, but could not find a good explanation for this problem.   从 Windows 版邮件发送
