Description Rahul Hinduja 2014-10-30 13:20:13 UTC

Description of problem:
=======================

When an attempt is made to create file/directories inside .snaps, it fails with wrong error message as "Stale file handle". It should fail with "Read only file system"

Version-Release number of selected component (if applicable):
=============================================================

glusterfs-3.6.0.30-1.el6rhs.x86_64


How reproducible:
==================

always


Steps to Reproduce:
===================
1. Enable uss on the volume
2. Cd to .snaps from the client


Actual results:
===============

[root@wingo .snaps]# mkdir a
mkdir: cannot create directory `a': Stale file handle
[root@wingo .snaps]# touch a
touch: cannot touch `a': Stale file handle
[root@wingo .snaps]# 


Expected results:
=================

[root@wingo .snaps]# mkdir a
mkdir: cannot create directory `a': Read-only file system
[root@wingo .snaps]# touch a
touch: cannot touch `a': Read-only file system
[root@wingo .snaps]#
