NFS_status_before_killing

Description of problem:

Services tab in Cluster is not showing the NFS status as DOWN when the service is down.

Version-Release number of selected component (if applicable): rhsc-2.1-qa18.el6ev.noarch


How reproducible: Always


Steps to Reproduce:
1. Select a cluster and click on the "Services" sub-tab
2. See the Status of any NFS service (it should be in the UP state) and note it down
3. Now go to the corresponding backed-end RHS node and kill the PID of the NFS service.
4. Ideally, the status should now get reflected in the UI and move to automatically to DOWN state.
  
Actual results: The status still shows as UP, even though the PID is killed or not running.


Expected results: The status should change automatically to reflect the current state in the RHS node.


Additional info: Screenshot attached.

Here I'm trying to kill the NFS PID of server 10.70.36.53 which is 2054

# ps aux |grep glusterfs |grep nfs
root      2054  0.2  0.4 326540 76012 ?        Ssl  00:39   0:00 /usr/sbin/glusterfs -s localhost --volfile-id gluster/nfs -p /var/lib/glusterd/nfs/run/nfs.pid -l /var/log/glusterfs/nfs.log -S /var/run/59bcb3fbd57e1040f17d5dbc753880dc.socket
 
# kill -9 2054
