Hi Maurice,
In the mail I sent, I proposed to add those Hosts to a new engine.
Those VMs should be registered as external VMs in your engine, and then you can
manage them and start, stop or reboot them.
I do *not* think this is correct. the new engine will only show the VMs.
it will not know of the storage domains or the disks, etc.
I think this will *not* work!
before doing that, please also set InstallVds parameter in the Data Base at
vdc_options table to false, to prevent the Host to be re-deployed when it is
being registered to the new engine (see [1]).
p.s. After stabilizing your environment,
you might be interested to upgrade to 3.5.
In oVirt 3.5, there is a new DR feature which should help recovering the engine
from those scenarios which you just encountered (see [2]).
[1] update vdc_options set option_value = false where option_name = 'InstallVds'
[2] http://www.ovirt.org/Features/ImportStorageDomain#Disaster_Recovery_flows

Maor

I am running 3.4.2 in that environment. I was wondering if there is a way to
start, stop, reboot the VMs that are present on the hosts that are still
running? I did not see any emails from Maor. Thanks

No back up, just the hard drive. The data is fine its the server board that

this brings me back to my original question below:
How do I, or can I use vdsm to interact with the VMs that are still present
on those hosts without the engine?
Hi Maurice,
What's the oVirt environment that you were running? 3.3, 3.4, 3.5?
When you say interact, is it about to start the VM that are you asking?
Could you please clarify? Have you tried the Maor's suggestion?
For now, I would say to start with:
http://wiki.ovirt.org/VdsClient
Thanks
Douglas

Yes the db and engine are offline
do you have a backup of the db to restore the engine?

Just to make sure, this means that when it comes to file system , etc..
you also have your storage resources available, right?
You lost the engine with the db, am I correct ?
I'm CCing someone that might have the exact answer for that.

Subject: [ovirt-users] Engine Hardware Crash
I just recently had the hardware that acts as the engine crash. I have a
blinking amber light on the server. I have servers on the remaining
hosts.
How do I, or can I use vdsm to interact with the VMs that are still
present
on those hosts without the engine?
