[Gluster-users] NFS expose subfolders only

[Shehjar Tikoo]

Like I said earlier, all folders are exported by default, just that they 
dont show up on showmount -e output unless explicitly set using the 
nfs.export-dir option. This means, if you know that a folder exists on the 
Gluster volume, you can mount it directly like I had shown in the previous 
email.
