From 03780d066ae7c78b969e2316dbde85e4ca0fcb85 Mon Sep 17 00:00:00 2001 From: Rajesh Joseph Date: Fri, 31 May 2013 18:17:21 +0530 Subject: nfs: AUTH support for exported sub-directories Problem: NFS allows exporting subdirectories but there is not support for providing AUTH on per directory basis. Fix: Modified nfs.export-dir to include AUTH parameters e.g. nfs.export-dir "/dir1(10.1.1.2),/dir2(10.1.1.0/24|host1) During mount operation NFS will check if the IP from where the connection is made is configured in the AUTH parameter, else the mount operation will fail with EACCES error. Updated admin-guide and volume set help message.
