Bug 1170502

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

If the snapshot-directory which bydefault is .snaps exists and it contains some data. After enabling USS, ls -la lists the .snaps (snapshot-directory) which will have adverse impact if user copies the complete directory which will copy the snapshots as well of .snaps.

We also have provision of configuring snapshot-directory, and with this user chances of seeing this is more.


[root@wingo test]# mount | grep vol0
inception.lab.eng.blr.redhat.com:/vol0 on /mnt/vol0 type fuse.glusterfs (rw,default_permissions,allow_other,max_read=131072)
inception.lab.eng.blr.redhat.com:/vol0 on /mnt/nvol0 type nfs (rw,vers=3,addr=10.70.34.50)
[root@wingo test]#
[root@wingo test]# pwd
/mnt/vol0/test
[root@wingo test]#

Before enabling USS ls -la shows .snaps and its contents as:
============================================================

[root@wingo test]# ls -lrta
total 0
drwxr-xr-x. 3 root root  38 Dec  4  2014 .
drwxr-xr-x. 7 root root 140 Dec  4  2014 ..
drwxr-xr-x. 3 root root  36 Dec  4  2014 .snaps
[root@wingo test]#
[root@wingo test]# ls .snaps
etc.5
[root@wingo test]#


After enabling USS, ls -la still shows .snaps and its contents as snapshots:
=============================================================================

[root@wingo test]# pwd
/mnt/vol0/test
[root@wingo test]# ls -lrta
total 4
drwxr-xr-x. 7 root root  140 Dec  4  2014 ..
drwxr-xr-x. 3 root root   38 Dec  4  2014 .
drwxr-xr-x. 2 root root 4096 Dec  4  2014 .snaps
[root@wingo test]# ls .snaps
rs1  rs2
[root@wingo test]# 


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

glusterfs-3.6.0.36-1.el6rhs.x86_64


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

always


Steps to Reproduce:
===================
1. Create 4 node cluster
2. Create a volume
3. Mount a volume to the client
4. Create a directory test
5. create .snaps inside test
6. cp -rf /etc etc5 in .snaps
7. ls -la from test, should show .snaps
8. ls .snaps, should show etc5
9. Enable USS
10. ls -la from test, it shows .snaps

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

It shows .snaps, which is now a virtual snapshot-directory


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

Once the USS is enabled, virtual snapshot-directory should not be visible
