Subject: [ovirt-users] oVirt Self Hosted Engine question
Dear all,
Dear Sean Cohen & Sandro Bonazzola,
I found your toturial about oVirt Self Hosted Engine from here, I have a
question about it. Would you help me?
http://www.ovirt.org/Features/Self_Hosted_Engine
My problem is:
First, I am Following the tutorial, In machine 'Srv1', type these two command
to install oVirt Host & Engine:
# yum install ovirt-hosted-engine-setup
# hosted-engine --deploy
Then I success create a Engine, and I can use web browser to access the
Engine in other PC.
Then, in second machine 'Srv2', type these two command to install second
oVirt Host.
# yum install ovirt-hosted-engine-setup
# hosted-engine --deploy
Did you supply there the same storage domain path used for the hosted engine
on first host? Because you should, if you want HA. It will then notice that
this path already has a VM image and will behave differently. See section 3.3
in that page - it should ask something like:
The specified storage location already contains a data domain.
Is this an additional host setup (Yes, No)[Yes]? yes').
My first problem is:
in second machine 'Srv2', after issue command 'hosted-engine --deploy',
and
it prompt '[ INFO ] Waiting for VDSM hardware info'. System will ask me and
wait my input for (1. Setup finish, 2. Restart VM, 3. Exit). I don't know
what should I do now.
My second problem is:
I use another PC web browser connect to my oVirt Engine, and ask Engine to
add Host 'Srv2' into Cluster.
This should not be needed, deploy should have done that for you.
It is done and successful. But when I try to
keep 'Srv2' is running, and make 'Srv1' to reboot.
How do you reboot it? Did you move to global/local maintenance?
I found that I cannot
connect to oVirt Engine anymore. I try to type 'hosted-engine --vm-start' in
first machine 'Srv1', but it has error and cannot start my Engine virtual
machine. Therefore, I cannot connect to my Engine anymore. How should I do
now?
If you still do not have data there, I think it will be easiest to just reinstall
everything from the beginning. Make sure to supply the same path when running
deploy on the second host. If you do have, or just feel like trying to fix
this anyway:
1. Please supply relevant logs from both hosts (/var/log/ovirt*, /var/log/vdsm*)
2. After you fix the problem with the engine not starting, I think you can
run again deploy on the second host and supply the same path. Not sure it will
work without cleaning a bit (removing configuration of hosted-engine and/or vdsm).
My three question is:
How to make my Engine become HA? Since when 'Srv1' reboot, the Engine cannot
jump to 'Srv2' automatically.
It should have happened automatically.
Best,
