df: `/root/.gvfs': Permission denied

在使用oracle账户检查本地磁盘情况时，总是出现df: `/root/.gvfs': Permission denied信息提示。

[oracle@rac1 ~]$ df -h

df: `/root/.gvfs': Permission denied

这个是RHEL6的一个已知的BUG 719272。
https://bugzilla.redhat.com/show_bug.cgi?id=719272
This typically happens when you run gnome-session or any other gnome app under root, autospawning gvfs-fuse-daemon. At first, Gnome apps should not be run under root nor su/sudo. As a second note, this is a design issue of FUSE mounts, denying access to other
users - system tools should be aware of it and ignore.

我们可以使用如下命令来跳过这个错误提示。
[oracle@rac1 ~]$ df -x fuse.gvfs-fuse-daemon

这个错误对系统来说是没有太多影响的，这里我们可以忽略。
