Re: [ovirt-users] Can HA Agent control NFS Mount?

Great to have your feedback guys!
So just to clarify some of the issues you mentioned;
Hosted engine wasn't designed for a 'single node' use case, as we do
want it to be highly available. This is why it's being restarted
elsewhere or even on the same server if no better alternative.
I hope you will keep this configuration in your design space as you move
forward.
As you can see it is likely to be a popular one. At a previous employer,
everybody in our development group had a single (powerful) machine
running VMware vSphere, with a hosted vCenter, to use as a development
VM testbed.
It's likely to be popular for people with few resources who want to run
in a fully supported configuration.
HA is great, but not every environment has the resources/requirement to
support it. oVirt has a lot to offer even a leaner environment and I
hope those environments continue to get attention as the product
matures. For example, I hope there is a reasonable story around upgrades
to future releases for single-node hosted configurations.
Having said that, it is possible to set global maintenance mode
as a first step (in the UI: right click engine vm and choose ha-maintenance).
Then you can ssh into the engine vm and init 0.
What is the recipe for a clean startup after shutdown?
Can we do 'hosted-engine --vm-start' while the system is in Global
Maintenance mode?
Thanks,
Bob
