[ceph-users] Issues with Ceph network redundancy using L2 MC-LAG

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 huxiaoyu@horebdata.cn
