DISK CRITICAL - /root/.gvfs is not accessible: Permission denied

I was getting Nagios Error to access /root/.gvfs on CentOS release 6.3 (Final) Operating System.

Solution 1:

/root/.gvfs file system is virtual file system that is not recognized by nagios tool. So you can umount this file system, it will not affect the usage mounted disk in system.

Run Command:

[root@dr01 ~]# umount /root/.gvfs

Now nagios monitor the disk correctly.

Solution 2:

My investigation showed that this problem appears due to special permissions set by FUSE on the .gvfs directory: nobody, even root cannot access it. It is only used internally by FUSE. Workaround for nagios is discussed here. We use the "-i ignored_path" key of the check_disk plugin.

So, in my case i modified /etc/nagios2/conf.d/localhost_nagios2.cfg in the following way:

define command{

  command_name  check_all_disks_plus

  command_line  /usr/lib/nagios/plugins/check_disk -w $ARG1$ -c $ARG2$  -u GB -A -i .gvfs

  }

define service{

  use                  generic-service

  host_name            localhost

  service_description  Disk Space

  check_command        check_all_disks_plus!20%!10%

  }
