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@xxxxxxxxxxxx <huxiaoyu@xxxxxxxxxxxx> 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.

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@xxxxxxxxxxxx > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
