[ovirt-users] all-in-one updated from 3.4.4 to 3.5.0 ok with reinstall of host part

[Gianluca Cecchi]

On a fedora 19 system where I had 3.4.4 all-in-one, I was able to upgrade
to 3.5.
vdsm part had problems I was able to solve reinstalling host from the
webadmin gui
Steps were:

- follow instructions for engine part --> ok
- verify connectivity of engine via new webadmin
- put host into maintenance
- stop vdsmd service
- yum update vdsm part and all other packages related to ovirt

When trying to start vdsm again I got

[root at tekkaman vdsm]# systemctl status vdsmd
vdsmd.service - Virtual Desktop Server Manager
   Loaded: loaded (/usr/lib/systemd/system/vdsmd.service; enabled)

I was not able to check wich part of --pre-start functions had failed..
I see inside the script

In logs I had only supervdsm.log

in vdsm.conf I have retained
net_persistence = ifcfg

even after reboot only supervdsm.log was populated...

Nevertheless a host reinstall from webadmin gui seemed to fix the problem
and after that it was able to start vdsm ad host part.
I was also able to upgrade DC/Cluster from 3.4 to 3.5 version.
Now that I'm on 3.5 next days I'll try to pass from F19 to F20... we'll see
