【求助】关于quota....

ye3312

开启quota
[root@localhost ~]# quotaon -av
/dev/sda5 [/var]: group quotas turned on
/dev/sda5 [/var]: user quotas turned on
然后编缉保存用户配额出现：edquota: Can't read quotas from file.
错误，很茫然，在线等答案，各位大大帮忙看下，谢谢

/etc/fstab 中 /dev/sda5 一行的mount有usrquota选项没？
在sda5的根目录下有quota.usr或者aquota.user文件没？
