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

해결

• To disable gvfs-fuse-daemon, the GVFS_DISABLE_FUSE environment needs to be set.
• Create the file /etc/X11/xinit/xinitrc.d/00-gvfs-disable-fuse.sh with the follwing contents:

Raw

GVFS_DISABLE_FUSE=1
export GVFS_DISABLE_FUSE

• Log out and log in again. If vncserver is running, restart it.
• For details, refer to Running GIO applications.

근본 원인

• On GNOME desktop environment, a hidden directory ~/.gvfs exists under home directory, gvfs-fuse-daemon mounts special filesystem to ~/.gvfs using FUSE system.

Raw

# mount
gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)

• An error occurs because a normal user cannot access other user's directories.

• Issue

  • When the normal user run df, "permission denied" occurs if root user login to GNOME.

  #df -kl
  Filesystem           1K-blocks      Used Available Use% Mounted on
  /dev/sda2             24670076   3751464  19665444  17% /

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

  Environment

  • Red Hat Enterprise Linux 6
  • GNOME Desktop Environment

  Resolution

  It needs to set GVFS_DISABLE_FUSE environment to disable gvfs-fuse-daemon.

  Add the the follows to /etc/environment so that a environment is set by default. Then, reboot system.

  GVFS_DISABLE_FUSE=1
  

  For details, refer to http://developer.gnome.org/gio/stable/ch03.html.

  Root Cause

  A hidden directory called ~/.gvfs exists under home directory, GNOME mounts special filesystem to ~/.gvfs to use FUSE system.

  # mount
  gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)
  

  df retrieves the infomation on mount points according to contents of /etc/mtab or /proc/mounts. In the case of a normal user, an error occurs without accessing other user's directories.
