Do you observe the same behaviour when you pull a cable? Maybe a flapping port might cause this kind of behaviour, other than that you should't see any network disconnects. Are you sure about LACP configuration, what is the output of 'cat /proc/net/bonding/bond0' On Tue, Jun 15, 2021 at 7:19 PM huxiaoyu@horebdata.cn <huxiaoyu@horebdata.cn> wrote:
Dear Cephers,
I encountered the following networking issue several times, and i wonder whether there is a solution for networking HA solution.
We build ceph using L2 multi chassis link aggregation group (MC-LAG ) to provide switch redundancy. On each host, we use 802.3ad, LACP mode for NIC redundancy. However, we observe several times, when a single network port, either the cable, or the SFP+ optical module fails, Ceph cluster is badly affected by networking, although in theory it should be able to tolerate.
Did i miss something important here? and how to really achieve networking HA in Ceph cluster?
best regards,
Samuel
