Hi all,
several times an hour occurs the following error. I'm using DRBD-Utils
8.3.11 with a drbd 8.3.13 kernel modul (yes, these are the versions in the
current ubuntu repository) on an Ubuntu-Server 12.04 LTS
(3.5.0-40-generic), the two-node-cluster is connected from NIC to NIC. I
never had any network problems with DRBD, so I hope anybody can help me.
I even tried it without the peer-to-peer connection with a normal network
connection, but same problem.
Here are my configs and the "PingAck did not arrive in time." Error from
syslog.
