quotacheck命令不能建立aquota.user和aquota.group檔案解決方法

在學習CentOS 6.5 磁碟配額quotacheck命令這裡，已經掛載分割區到/home目錄下，執行命令然後遇到錯誤提示，最後找到了原因，解決了問題。

解釋：aquota.group與aqouta.user分別是組以及使用者磁碟配額需要的組態檔。如果沒有這兩個檔案，則磁碟配額是不會生效的。

執行命令
# quotacheck -augv123456789101112 [root@root ~]# quotacheck -augv
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.

[root@root ~]# ll /home/

出現上面的錯誤，提示不能建立/home/aquota.user /home/aquota.group 這2個檔案，沒有這個檔案，沒有許可權操作。在home目錄也沒有發現這2個檔案。

原因找到了，需要關閉selinux，然後就可以執行了。關閉selinux的命令是#setenforce 0

重新執行#quotacheck -auvg 就可以了，同樣也會有錯誤提示，不用管他，之後在/home目錄就有組態檔了。
