Hello, We are currently experiencing a weird "PingAck" timeout on a system with two nodes, and an active/passive configuration. The two nodes are using a cross-cabled connection in a bonded two Giga NIC cards. This network never goes down and used only for DRDB and CRM cluster data exchange. It's barely used (very light load). We are running SLES 11 SP2, DRBD release 8.4.2, and pacemaker 1.1.7.
We couldn't find a DRBD configuration option to setup the number of retries before giving up. Our concern is that we do not understand how a PingAck can timeout over such a reliable media? Any insight into this would be much appreciated. On the same note, are there any guards against it? Any best practices (setups) we could use to avoid this situation? Thanks for any help, Youssef
