We have a handful of servers running gluster, equipped with either CX354A or CX456A Infiniband adapters. I am thinking about bonding to fully utilize the two ports each of them has.
However, it looks like mode=1 is the only one working while the network wouldn’t start at all when setting to mode=0. https://community.mellanox.com/s/article/howto-create-linux-bond--lag--interface-over-infiniband-network said that mode=1 (active-backup) is the only meaningful bonding policy in IPoIB. Can somebody explain a little bit about it. Why is mode=1 the only meaningful one?
Besides, does that work for RDMA as well?
