Gluster strange issue with shared mount point like seprate mount.

Question

I have two nodes and for experiment i have install glusterfs and create volume and successfully mounted on own node, but if i create file in node1 it is not showing in node2, look like both behaving like they are separate.

node1

10.101.140.10:/nova-gluster-vol
                      2.0G  820M  1.2G  41% /mnt

node2

10.101.140.10:/nova-gluster-vol
                      2.0G   33M  2.0G   2% /mnt

volume info split brian

$ sudo gluster volume heal nova-gluster-vol info split-brain
Gathering Heal info on volume nova-gluster-vol has been successful

Brick 10.101.140.10:/brick1/sdb
Number of entries: 0

Brick 10.101.140.20:/brick1/sdb
Number of entries: 0

test

node1

$ echo "TEST" > /mnt/node1
$ ls -l /mnt/node1
-rw-r--r-- 1 root root 5 Oct 27 17:47 /mnt/node1

node2 (file isn't there, while they are shared mount)

$ ls -l /mnt/node1
ls: cannot access /mnt/node1: No such file or directory

What i am missing??
