Having a shared /var/lib/nfs make sense with active-standby configurations because the nfs servers does not talk with each other, so I think it's normal to have instability. > Then I tried to find a way to keep just the rmtab file synchronized on > both nodes.

I've configured a lot of A/A setup with exportfs without having problems. What's the boot order of your resources? Are you sure you're removing first of all the IP and then exportfs? I'm asking this because one of my problem was about the connections keep opened by the clients (i was removing first exportfs). -- RaSca Mia Mamma Usa Linux: Niente รจ impossibile da capire, se lo spieghi bene!
