Well, I futzed around for about 3 hours bouncing the engine and the host,
and finally I hit some combination that allowed me to save the
configuration of the ovirtmgmt network on this host. I had to update my
DHCP configuration to force the correct static IP address to the MAC (not
sure why the
Not sure about recovering your cluster on a 4.5 install with a 4.4 backup.
I would also like to know if that is possible.
As a separate note, if you really need to install 4.4 instead of 4.5; I
managed to install a 4.4.10 hosted engine recently by
- extracting the ova from the ovirt-appliance rpm
Good afternoon all,
Welcome to the third part of my trilogy of disaster recovery woes. Much of
my woe is self inflicted, but I have learned enough from this that I now
know how to ask the right question about the original problem that got me
here.
After reinstalling the engine from the ground
If you use Gluster, don't forget to bump the OP version once you are happy with
your tests.It controls the backward compatibility, but also some internal
mechanisms and optimizations.

The last thing I need is the complication of having the engine hosted on
the cluster. It's way too easy to shoot yourself in the foot that way.

It's definitely possible. I had an issue with my 4.4->4.5 upgrade (always
make a backup first) and wanted to switch my

You don't need to reinstall the whole system.Get an install media, boot from it
and pick troubleshoot.
Then follow https://access.redhat.com/solutions/3486741 (requires a
subscription, but you can get one on https://developers.redhat.com/ -> bottom
of the page).

Installing oVirt is not so easy as stated, i am struck up in FQDN resolution
, i have this FQDN (vmanager.headache.com) resolve to ip 10.1.1.6 in DNS

I think that I am progressing in troubleshooting.
it seems like the certificates for the vmconsole-proxy were not renewed
like the other certificates during engine-setup --upgrade
[root@vs-inf-prd-ovt-fr-501 ~]# openssl x509 -in
/etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer -noout -text
This came in just as the engine came up.
The final pieces of the puzzle were:
The database@server notation expressed in the logs is cool, but is not how
it is expressed to actually connect. That threw up a red herring.

Thanks Nardus,
ProxyPreserveHost did the trick, all seems to be working now.

This worked for us:
edit /etc/httpd/conf.d/ovirt-engine-grafana-proxy.conf
add "ProxyPreserveHost On"
should look like this now:
LoadModule proxy_module modules/mod_proxy.so

Hello everyone,
We have the same problem on our oVirt 4.4.10 Production server.
ssh connection to vmconsole@engine was previously working in 4.4.6. but it
stopped working at some point, maybe since upgraded to 4.4.10
contrary to a working test environment that was directly installed on
4.4.10,
I've not restored from a backup or changed the grafana databse user
password, no idea why this has 'just' stopped working (or when as I don't
look at grafana that often).
I tried updating the grafana db user password, but still no joy...
I grabbed the password from
Hi,
the first thing to check is the firewall: check with wget if the
servlet can be reached (method not allow error means you have
connected)

It looks like a permanent fix was put in place in 4.5.

You can find it by going to the Monitoring Portal -> Gear Icon on the

Thank You Strahil, I was actually able to use the node snapshot to revert a

This time I'll wait till its completed its testing phase and maybe get a small
lab to test the upgrade on, I need to remove the testing Repo as well, I was
not aware that it was
