[ovirt-users] Ovirt nodes lose up status

[Fabien CARRE]

Hello,
I am experiencing an issue with on my current ovirt DC.
The setup is 2 machines running Ovit Nodes connected to a LaCie 12big Rack
Fibre 8, the nodes are connected to both controllers.. This configuration
has worked fine for a couple of weeks.

Recently the nodes go from Up status to Non Operational. When I activate
them back they don't last more than 2 minutes.


/var/logl/messages on both nodes shows the same errors :

Has anyone met such a problem ?

Thank you
