Description Saurabh 2015-09-04 08:03:17 EDT

Description of problem:
Mounted the volume using the nfs-ganesha and took snapshot. From snapshot there is not data seen in .snaps/<snapshot-name>

Version-Release number of selected component (if applicable):
glusterfs-3.7.1-14.el7rhgs.x86_64
nfs-ganesha-2.2.0-7.el7rhgs.x86_64

How reproducible:
always

Steps to Reproduce:
1. create a volume of 6x2 type

2. configure nfs-ganesha, export the volume created in step1

3. on client mount the volume over nfs with vers=3 or 4,

3a. create some data inside the mount-point

4. enable uss using command
   gluster volume set <volname> uss on

5. create a snapshot using command,
   gluster snapshot create <snapname> <volname>

6. activate snapshot created in step 4,
   gluster snapshot activate <snapname>

7. cd /mount/point/volname/.snaps/<snapshot-name>

8. ls -lR

Actual results:
step 8 fails, as there is no data inside snapshot directory. Basically the data is not fetched.

Expected results:
Step 8 should fetch data from the server, as the data is fetched from glusterfs(native mount).
