seems i have just found out the reason, the problem only occured on the
machine with scsi hdd.
i have setup 3 scsi machines:
machine A - adaptec 29160, ibm 18g scsi
machine B - adaptec 29160, seagate 9g scsi
machine C - adaptec 2940UW, seagate 9g scsi
both machines got the "Invalid argument" problem, but i have setup 2 ide hdd
machines last night, and don't have such problem.

[root@xfs root]# repquota -vug /
repquota: Not all specified mountpoints are using quota.
