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:
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?
