如何理解配额的输出？

在科学的Linux服务器上（实际上是一个集群的一个节点），我运行

$ quota -vs Disk quotas for user tim (uid 12345): Filesystem blocks quota limit grace files quota limit grace /dev/vdb 12 126G 126G 3 8389k 8389k 

1. 根据https://www.isg.inf.ethz.ch/HelpHowToCheckQuotaLinux ， blocks是使用千字节的磁盘空间，但我发现我的家已经使用了超过12千字节：

    $ du -sh ~ 4.1G /afs/user/tim 

2. 该网页还表示， file是file的数量，但我有我的家或当前目录多于3个文件。

那么我怎么理解quota输出的含义呢？

mount输出：

• zimbra邮件配额视图命令行
• 奇怪的行为与ldap和getent或repquota
• 从备份脚本中的Fedora 25 tar错误aquota.user：不能时间操作不允许
• 内核中不支持Ubuntu配额格式
• 不知道为什么我在GAE（Java）上获取配额错误
