The heartbeat code is very careful to use the same physical interfaces as 1) the cluster network 2) the public network If the first breaks, the OSD can't talk with its peers. If the second breaks, it can't talk with the monitors or clients. Either way, the OSD can't do its job so it gets marked down. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com On Sat, Jul 19, 2014 at 3:08 AM, Haomai Wang <haomaiwang at gmail.com> wrote: > Hi all, > > Our production ceph node each has two NIC, one used by heartbeat > another used by cluster_network. > > By accident, the heartbeat NIC is broken but the cluster_network NIC > is healthy.
