[ovirt-users] Node not talking NFS to Node.

Hello Been trying to resolve a problem with my second node which does not want to connect : one of my 2 nodes are not connecting, the problem is that the Node cant talk NFS to Node. the node used to function fine, after performing a hardware upgrade and bringing the system back up it seems to have come up with this issue. we also performed a yum update, updated around 447 packages. Can someone please help me with this. Thanks Sol
