Description of problem:
This issue is seen on both nfs and glusterfs mounts.
The problem is that with cd to the mount-point fails for a non-root user, whereas with "root" user it works. 

Problem is seen after add-brick and rebalance operation.
Before that the things were working fine for creating file /directories with non-root user.


Version-Release number of selected component (if applicable):
glusterfs-3.4.0.38rhs-1

How reproducible:
seen only one volume on one cluster, but not on other.

Steps to Reproduce:
1. once the disks become full on all nodes, add another disk to all the nodes of the cluster

2. add brick on new disk using gluster volume command

3. start rebalance operation

4. on client, try to cd to the nfs/glusterfs mount-point as non-root user

Actual results:
[root@rhslong03 ~]# su qa1
[qa1@rhslong03 root]$ cd /mnt/nfs-test
bash: cd: /mnt/nfs-test: Permission denied
[qa1@rhslong03 root]$ cd


Expected results:
cd to the mount-point if allowed from root user is successful, then it should be successful as non-root user also.
