Description gregor 2016-10-16 20:44:24 UTC

Description of problem:
After a failed installation I removed all the ovirt and vdsm components, rebooted the machine and started from the beginning. Now the installation did not start because vdsm can't start.

Version-Release number of selected component (if applicable):
Centos 7

Steps to Reproduce:
1. yum remove ovirt-* vdsm-* libvirt-* python-ovirt-engine-sdk4 postgresql-* qemu-*
2. reboot
3. yum -y install ovirt-hosted-engine-setup ovirt-engine-appliance guster-server vdsm-gluster
4. hosted-engine --deploy

Actual results:
The installer stucked at "[ INFO  ] Stage: Environment setup"

Expected results:
The installation should be possible

Additional info:
These are relevant lines from /var/log/vdsm/supervdsm.log

Comment 1 Michal Skrivanek 2016-10-17 07:19:52 UTC

I suppose this is an incorrect cleanup. Simone?

Comment 2 Sandro Bonazzola 2016-10-17 07:27:56 UTC

Nir can you have a look at above traceback?

Gregor, can you please provide a sos report of the host?

Comment 3 Simone Tiraboschi 2016-10-17 07:56:45 UTC

> I suppose this is an incorrect cleanup. Simone?

Yes, I think so.

Comment 4 gregor 2016-10-17 09:01:57 UTC

In the meantime I followed this instruction which did not help:

https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-failed-install

Is it save to upload the sosreport here? I read through this article: https://access.redhat.com/solutions/3592

Comment 5 gregor 2016-10-17 21:01:32 UTC

Because the server has to be finished and shipped to my customer I decided to reinstall the whole operating-system. 
This is a very bad solution but after 20 hours of try-and-error I have to find any solution.

Thanks for your help.
