在学习CentOS 6.5 磁盘配额quotacheck命令这里，已经挂载分区到/home目录下，执行命令然后遇到错误提示，最后找到了原因，解决了问题。
解释：aquota.group与aqouta.user分别是组以及用户磁盘配额需要的配置文件。如果没有这两个文件，则磁盘配额是不会生效的。
执行命令
# quotacheck -augv

出现上面的错误，提示不能创建/home/aquota.user /home/aquota.group 这2个文件，没有这个文件，没有权限操作。在home目录也没有发现这2个文件。
原因找到了，需要关闭selinux，然后就可以执行了。关闭selinux的命令是#setenforce 0
重新执行#quotacheck -auvg 就可以了，同样也会有错误提示，不用管他，之后在/home目录就有配置文件了。
