Hi, This is why, Linbit should publish in the documentation, a list of hardware (NIC's) tested and certified as fully working. I have seen this problem here in the list a couple of times in the last month. It's kind of sad spend time and a lot of money in good enterprise network hardware, and in the end things don't work as they should. What do you guys think of this?
