[ovirt-users] ovirt node pxe and thinpool errror in status

[Gianluca Cecchi]

Hello,
I'm experimenting to install ovirt ng node 4.2 via pxe and it seems all
went ok.
Only problem I have is that opening terminal session I get this traceback
that seems related to thinpool

Traceback (most recent call last):

Any hint?

I installed from 4.2 iso and then applied the
ovirt-node-ng-image-update-4.2.1.1-1.el7.centos.noarch yum update
The problem remains

At the moment it is not linked with any engine, also installed.
I can go to the Admin Console web page and I see, clicking inside
"Virtualization" left tab, that on the right dashboard I have a yellow
triangle to the right of the "Health" word...
But I don't exactly understand the source of the warning...

Thanks for any hint related,

Gianluca
