Subject Re: Switching backup VR to master manually
Date Mon, 20 May 2019 09:09:59 GMT
Hi Rakesh,

When backup upgraded to newer version and master is destroying backup suppose to become master
and pickup the connections automatically. RVR is there to avoid downtime.
Changing the state of backup is time critical and practically it is difficult. In your case
it seems there is bug, due to that connections info is  shared.

Is there a way to switch the backup virtual router to master state manually
by triggering something or running some scripts?

Currently when I restart network with cleanup option, first the backup will
be upgraded to newer cloudstack version and when the master is destroyed
then only backup becomes the master and this process might take atleast
5-10 seconds. In the meantime there will be dowmtime. Is there a way to
quickly change the state?

Im thinking on stopping the keeaplived on master so that backup will become
master quickly. Is there a better way to do it?

Thanks and regards
Rakesh venkatesh
