I was hoping if i can get some help with the below oVirt scenario:
*Problem Statement*:-
Is it possible to change scheduler optimization settings of cluster using
ansible or some other automation way
*Description*:- Do we have any ansible module or any other CLI based
approach which can help us
When you ran `engine-setup` did you enable cinderlib preview (it will
not be enabled by default)?
It should handle the creation of the database automatically, if you
didn't you can enable it by running:
`engine-setup --reconfigure-optional-components`

Hi Arik,
Ok, we'll try with that one.
The oVirt version we use is 4.4.1.

We made several fixes in that area since then, however I see this still
happens on
output from engine.log when I try to access the admin page is as follows:
2020-09-30 06:33:03,324-07 INFO

I was able to finish update manually creating hosted_storage domain from new
engine web interface
after first failure, in this case it was created with format V4 and ansible
playbook doesn't
recreate it, after updating engine and host updating cluster compatibility
level to 4.4 also updated
The problem we face right now is that, since the engine is a VM of
itself, we can't bring it back up to apply the new configuration.
Is there any way to fix this? Without reinstalling preferably.

I hadn't installed the necessary packages when the engine was first
installed.
However, running 'engine-setup --reconfigure-optional-components'
doesn't work at the moment because (by design) my engine does not have a
network route outside of the cluster. It fails with:

You can use this ansible module and assign your scheduling policy:

Some of the work to implement that went into 4.4, where it will recover

a power outage, it will restart them). However, I believe there is no

Are you trying to use the same storage domain ?
I hope not, as this is not supposed to be done like that.As far as I remember -
you need fresh storage.

I would suggest to do it via one of the sdks, for example python

Alternatively use ansible, you can also call that from cli.

Ya.. that is a lot easier.

The script is smart enough to wait for the engine to be fully active.

Seems like this could be my issue
This could be where had issue with rebuild of ovirt-engine. And then had
to scrape out the disk files to then import them back in. I then moved the

I would create an ansible playbook that will be running from the engine:
1. Check the engine's health page via uri module and wait_for (maybe with a
regex)
Healthpage is : https://engine_FQDN/ovirt-engine/services/health
2. Use ansible ovirt_vm module to start your vms in the order you want
3.
i would like to eventually go ansible route.. and was starting down that

One question: How /where do you set this saved new and delicious script so

I had a script based around ovirt-shell which I re-wrote as a script
around the Python SDK4 which I run on my engine during the startup

Last metadata expiration check:
In your case it seems reasonable, but you should test the 2 stripe sizes (128K
vs 256K) before running in production. The good thing about replica volumes is
that you can remove a brick , recreate it from cli and then add it back.

If you can do it from cli - use the cli as it has far more control over what
the UI can provide.
Usually I use UI for monitoring and basic stuff like starting/stopping the
brick or setting the 'virt'group via the 'optimize for Virt' (or whatever it
was called).

No, this is fresh storage(completely empty dir) and hosted-engine deploy
creates V5 format domain in V4 DC,
where master domain is also V4, I can see this in web available from local
deploy VM. And storage is
automatically renamed by deploy script.
