在64位RHEL6操作系统上使用ext4文件系统设置配额

Question

使用ext4 FS设置一个新的64位RHEL 6服务器。以前只使用过ext3和32位RHEL5。不管我怎么努力，我都不能让它起作用。

当前的挂载设置(来自“挂载”命令)：

/dev/sda7 on / type ext4 (rw,noatime)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,noexec,nosuid)
/dev/sdb1 on /backup type ext4 (rw)
/dev/sda1 on /boot type ext4 (rw,noatime)
/dev/sda8 on /home type ext4 (rw,noatime,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0)
/dev/sda2 on /tmp type ext4 (rw,noexec,noatime)
/dev/sda6 on /usr type ext4 (rw,noatime)
/dev/sda5 on /var type ext4 (rw,noatime,usrjquota=aquota.user,jqfmt=vfsv0)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

本质上试图在/home上获取用户/组配额，在/var上获取用户配额。在aquota.user和/var上创建/home和/var文件：

-rw-r--r-- 1 root root 0 Nov 17 13:37 /home/aquota.group
-rw-r--r-- 1 root root 0 Nov 17 13:37 /home/aquota.user
-rw------- 1 root root 0 Nov 17 11:43 /var/aquota.user

当我进行验证码时，我得到：

引号-vguma

quotacheck: WARNING -  Quotafile /home/aquota.user was probably truncated. Cannot save quota settings...
quotacheck: WARNING -  Quotafile /home/aquota.group was probably truncated. Cannot save quota settings...
quotacheck: WARNING -  Quotafile /var/aquota.user was probably truncated. Cannot save quota settings...

然后我尝试商数并得到：

商-av

quotaon: Cannot find quota file on /home [/dev/sda8] to turn quotas on/off.
quotaon: Cannot find quota file on /home [/dev/sda8] to turn quotas on/off.
quotaon: Cannot find quota file on /var [/dev/sda5] to turn quotas on/off.

已安装配额rpms：

rpm -qa|grep -i配额

quota-3.17-16.el6.x86_64
quota-devel-3.17-16.el6.x86_64

有什么想法，我做错了什么，或我应该调整，以使配额工作，就像在ext3 3/32位？

弄明白了。必须先删除。*文件。似乎j配额不喜欢它们存在，即使是0字节文件，就像正常的配额设置一样。
