quota問題

freedom0705

我輸入quotacheck -auvg
會出現
quotacheck: your kernel probably supports journaled quota but you are not
                    using it. consider switching to journaled quota to avoid
                    running quotacheck after an unclean shutdown.
quotacheck: Cannot remount filesystem mounted on / read-only so
                    counted values might not be right.
Please stop all programs writing to filesystem or use -m flag to force
checking.
quotacheck: Cannot remount filesystem mounted on /home read-only so
                    counted values might not be right.
Please stop all programs writing to filesystem or use -m flag to force
checking.

我如果用quotacheck -auvgcm  有不一樣的錯誤訊息
quotacheck: your kernel probably supports journaled quota but you are not
                    using it. consider switching to journaled quota to avoid
                    running quotacheck after an unclean shutdown.
quotacheck: Scanning /dev/sda2[/home] quotacheck: lstatcannot stat
                    /home/lin/.gvfs: 拒絕不符權限的操作
Guess you'd better run fsck first
exiting....

我有去改/home/lin/.gvfs的權限
但沒辦法改                                                                                
我的OS是fedora 11
/ 和/home 都是ext4日誌檔案系統
我在/etc/fstab 裡面的defaults有加上,usrquota,grpquota
也有remount過
請問出現這些訊息是哪邊出錯了
