<div>Hi Pedro,</div>
<div> </div>
<div>sorry, I am not following the thread from the beginning. But we can see from the log excerpt that your eth1 NIC has disapeared for half a minute. You should check the whole log file for what was happening at that time. Could it be a network service restart?</div>
<div>As Lars already answered you, once DRBD resource went StandAlone, you have to reconnect it manually. There are some properties available in drbd.conf that defines the time period or number of attempts after which it gaves up trying to reconnect.<br>
</div>
