[root@Box48 /]# ls -ldZ /mnt
drwxr-xr-x. 2 root root system_u:object_r:mnt_t:s0 4096 Aug 10 13:40 /mnt
I meant ls -ldZ /mnt/box48
I saw this a few times and it was related to SELinux as it was missing the label, which sort of explain why you can mount but cannot see the content, it may also be that the user (bobg) that is used to mount the drive do not have permission to that directory.
