Hi,
we are running a 3 Node Setup with a DRBD9 SharedStorage between the two strong Servers since a while now - no problems at all.

Today something strange occured, all of the sudden the communication between the the nodes 1 & 2 failed and the Nodes rebooted several times.

I found the following in the log:
Code:
Mar 11 14:07:50 pve1 kernel: [  311.016122] vmbr0: received packet on eth0 with own address as source address
Mar 11 14:07:55 pve1 kernel: [  315.843895] net_ratelimit: 6534 callbacks suppressed

The Provider told us he had seen a lot of multicast traffic in the same timeframe.
After that period the messages in the log disapeared an everything runs again as expected.

Can anyone give a hint what happened here?
