[ovirt-users] Adding another host to my cluster

Thu May 12 21:24:09 EDT 2016

Hi Charles,

Thanks for the suggestion.

I cleaned up again using the bash script from the
recoving-from-failed-install link below, then reinstalled (yum install
ovirt-hosted-engine-setup).

I enabled NetworkManager and firewalld as you suggested. The install stops
very early on with an error:
[ ERROR ] Failed to execute stage 'Programs detection': hosted-engine
cannot be deployed while NetworkManager is running, please stop and disable
it before proceeding

I disabled and stopped NetworkManager and tried again. Same result. :(

Any more guesses?

Cheers,
Gervais

Hey Gervais,

Try enabling NetworkManager and firewalld before doing the hosted-engine
--deploy.  I have run into problems with oVirt trying to perform tasks on
hosts where firewalld is disabled, so maybe you are running into a similar
problem.  Also, I think the setup script will disable NetworkManager if it
needs to.  I know I didn't manually disable it on any of the boxes I
installed on.

Hi Wee
(and others)

Thanks for the reply. I tried what you suggested, but I am in the exact
same state. :-(

I don't want to completely remove my hosted engine setup as it is working
on the two other hosts in my cluster. I did not run the rm -rf stes listed
here (
https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-failed-install
<
https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-failed-install>)
that would wipe my hosted_engine nfs mount. If you know that this is 100%
necessary, please let me know.

I did:
hosted-engine --clean-metadata --force-cleanup --host-id=3
run the bash script to remove all of the ovirt packages and config files
reinstalled ovirt-hosted-engine-setup
ran "hosted-engine --deploy"

I'm back exactly where I started. Is there a way to run just the network
configuration part of the deploy?

Since the last attempt, I did upgrade my hosted engine and my cluster is
now running oVirt 3.6.5.

Cheers,
Gervais

Hi,

I used to have a similar problem where one of my host can't be deployed due
to the absence of ovirtmgmt bridge. Simone said it's a bug (
https://bugzilla.redhat.com/1323465 <https://bugzilla.redhat.com/1323465> )
which would be fixed in 3.6.6.

This is what I've done to solve it:

1. In the web UI, set the failed host to maintenance.
2. Remove it.
3. In that host, run a script from
https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-failed-install
<
https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-failed-install

4. Install ovirt-hosted-engine-setup again.
5. Redeploy again.

Hope that helps

Hi All,

I'm trying to add a third host into my oVirt cluster. I have hosted engine
setup on the first two. It's failing to finish the hosted-engine --deploy
on this third host. I wiped the server and did a CentOS 7 minimum install
and ran it again to have a clean machine.

My setup:
CentOS 7 clean install
yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm <
http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm>
yum install -y ovirt-hosted-engine-setup
yum upgrade -y && reboot
systemctl disable NetworkManager ; systemctl stop NetworkManager ;
systemctl disable firewalld ; systemctl stop firewalld
hosted-engine --deploy

hosted-engine --deploy always throws an error:
[ ERROR ] The VDSM host was found in a failed state. Please check engine
and bootstrap installation logs.
[ ERROR ] Unable to add Cultivar2 to the manager
and then echo's
[ INFO  ] Waiting for VDSM hardware info
...

    Log file is located at
/var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20160509130658-qb8ev0.log

Full output of hosted-engine --deploy included in the attached zip file.
I've also included vdsm.log (There is more than one tries worth of tries in
there).
You'll also find the ovirt-hosted-engine-setup-20160509130658-qb8ev0.log
listed above.

This is my "test" setup. Cultivar0 is my first host and my nfs server for
storage. I have two hosts in the setup already and everything is working
fine. The host does show up in the oVirt admin, but shows "Installed Failed"
<PastedGraphic-1.png>

Trying to reinstall from within the interface just fails again.

The ovirt bridge interface is not configured and there are no config files
in /etc/sysconfi/network-scripts related to ovirt.

I also have a series of stuck tasks that I can't clear related to the host
that can't be added... This is a secondary issue and I don't want to get
off track, but they look like this:

I'd appreciate any help that can be offered.
