Oh. When you say reconnect do you mean reconnecting ethernet or
drdbadm reconnect? If the former, too late and I will have to do it
all again. If the latter, I have not done it yet so I should be good.
In any case, here is the output with db1's ethernet cable reconnected:
root at db1:~# drbdadm get-gi r0
root at db1:~#
root at db2:~# drbdadm get-gi r0
root at db2:~#
So, from what you said, I *should* have
the same, but as you can see the last character is different. Loads of fun.
