Suppose I have only one management server and I want to take it down for
maintenance. What is the procedure to deploy the management server on a
different machine?
I tried the following on the new machine:
(i) Completed all the steps from Chapter 2 in the
Apache_CloudStack-4.0.2-Quick_Install_Guide-en-US.pdf
(ii) Copied all files from /etc/cloud, /usr/lib64/cloud, /var/lib/cloud
from the old machine to the new one.
(iii) Took dumps of the databases cloud, cloudbridge, cloud_usage from old
machine and then put them in the new machine.
(iv) Changed the ip in /etc/cloud/agent/agent.properties and
/etc/cloud/management/db.properties from 10.3.3.57 to 10.3.3.56
But i still get the error
