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. But osds report the broken NIC node is unavailable, so
monitor decide to kick out the node.
I'm not sure what
Hi there,
OS: RHEL 7.0 x86_64
ceph: 0.80.4
ceph-deploy: 1.5.9
(disks have been zapped first)
I think there might be a typo in the documentation here:
http://ceph.com/docs/master/rados/deployment/ceph-deploy-osd/#prepare-osds
If I follow by doing this:
ceph-deploy osd prepare ceph-osd1:sdc:/dev
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 do
Oh, it's our fault.
Public_addr and cluster_addr use the same NIC(eth1). But we found during
recovering heartbeat may timeout because of busy traffic. I *misunderstood* the
mean of heartbeat and use another NIC(eth0) address for heartbeat to avoid
timeout.
From your points, it's easy to unders

IMHO setting OSD crush map host may be easier from OSD configuration section
as follows:
[osd.5]
host = realhost
osd crush location = host=crushost
