well.. In both nodes, I need:
     # drbdadm disconnect all
     # ethtool -K eth1 rx off tx off sg off tso off
     # drbdadm connect all

this is all ??

In my case, I have a exclusive nic for drbd (eth1)...
I believe, that isn't necessary apply this configuration for all
others network interfaces only in drbd interface (eth1) correct ??
