[ovirt-users] Adding another host to my cluster

[Gervais de Montbrun]

Hi Nir,

Thank you for you input.

It was suggest that I try starting vdsm from the shell so I could see the
output in an effort to solve my issue:

Hi Charles,

I think the problem I am having is due to the setup failing and not
something in vdsm configs as I have never gotten this server to start up
properly and the BRIDGE ethernet interface + ovirt routes are not setup.

I put the logs here:
https://www.dropbox.com/sh/5ugyykqh1lgru9l/AACXxRYWr3tgd0WbBVFW5twHa?dl=0

hosted-engine--deploy-logs.zip # Logs from when I tried to deploy and it
failed
vdsm.tar.gz # /var/log/vdsm

Output from running vdsm from the command line:

[root at cultivar2 log]# su -s /bin/bash vdsm


This cannot work unless supervdsmd is running...

Vdsm tries to connect to supervdsmd on startup, and if it is not running
it will fail.

You can do:

systemctl start supervdsmd

And they you can run vdsmd from the shell.

But why do you need to run vdsm from the shell?
