------------------------------------------

             Summary: Restarting services monitored in VR fails while the monitoring script logs it succeeded
                 Key: CLOUDSTACK-6503
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6503
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Virtual Router
    Affects Versions: 4.3.0
         Environment: Tested on KVM hosts, but I anticipated that this would happen other hypervisors.
            Reporter: Takashi Sugano


In VR the service command reports it succeeded to restart a service while it actually didn't in some cases where, for example, the service command binary  is accidentary removed. This can be reproduced as follows:

root@r-3-VM# service dnsmasq stop; rm -f /usr/sbin/dnsmasq

Since the monitorServices.py script relies on the service command to know if restarting a service gets done successfully or not, the script keeps writing "The process dnsmasq is recovered successfully" in /var/log/messages forever.
