Re: [Deploy vm independent to ACS]

[Dag Sonstebo]

Hi Gian Paolo,

I would strongly advise against this – sooner or later you may e.g. have an HA 
event where your VMs end up on the host CloudStack wasn’t aware of – which 
would cause you a lot of problems.

You haven’t stated why you want to do this? It sounds like you are much better 
off just running the new host as a separate host altogether rather than adding 
it to a CloudStack managed cluster.

Re: Upgrade CentOS 6.5 to 7

[Dag Sonstebo]

+1 for Oliver’s suggestion – you would run into a lot of issues trying to 
upgrade from 6.5 to 7, you are much better off simply building a new CentOS7 
management server and pointing this at your existing database before 
decommissioning your old 6.5 server.

Just keep in mind to *not* use the “deploy-as” option with 
cloudstack-setup-databases – simply use the instructions for “additional 
management servers” in 
http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/management-server/index.html#additional-management-servers
 . It’s also a good idea to back up your databases beforehand.

Hi,

upgrades where runlevel management significantly changes is always
connected with a lot that can go wrong.

Its not as worst as upgrading an older ubuntu to ubuntu 16, but you
might end up being forced to replace the node.

Its suggestable that you simply create fresh centos 7 and migrate the
services.

But in the very end, centos 6 has still some years left of update
maintenance. So as long as you dont run into any compatibility issues,
where you need centos 7 with its newer versions, you should stay with
your centos 6.
