[Users] Lvm vgs failed on allinone setup

Tue Nov 27 14:42:47 UTC 2012

So I have reinstalled by doing: 
engine-cleanup 
rm -rf /home/iso 
rm -rf /home/storage 
rm /etc/exports 
export LANG=en_US.UTF-8 
engine-setup

Now when asked I have select NFS for the default storage type.

I've done the 5th step at http://blog.jebpages.com/archives/up-and-running-with-ovirt-3-1-edition/ .
(Copy and paste - BEGIN)
click on the storage tab and highlight the iso domain you created during the setup-script. In the pane that appears below, choose the “Data Center” tab, click “Attach,” check the box next to your local data center, and hit “OK.” Once the iso domain is finished attaching, click “Activate” to, uh, activate it.
(Copy and paste - END)

I've taken a moment to check /var/log/messages and I have noticed:

Any ways I've decided to reboot just to see if everything went ok. When examining Storage tab I see how local-iso-share (my ISO domain type) is shown as green (activated) and then red (maintenance).

Taking a look at /var/log/messages I've seen:

Nov 27 14:26:38 server vdsm Storage.LVM WARNING lvm vgs failed: 5 [] [' Volume group "c20da291-baf5-480a-b314-b775a6dde6e8" not found']

What am I missing?

Thank you.

If iSCSI is the problem I think I will reinstall oVirt by choosing NFS for default storage and not iSCSI.
