Ceph » RADOS

ceph osd metadata reports wrong "back_iface". Example: ceph osd metadata 0

{
"id": 0,
"arch": "x86_64",
"back_addr": "[2001:7b8:80:1:0:1:2:1]:6820/1003144",
"back_iface": "ens2f0",
...

Reports "back_iface": "ens2f0" instead of "internal" interace of openvswitch port:
root@osd1:~$ ovs-vsctl show

osd1:~$ ip -6 a s ceph
8: ceph: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 state UNKNOWN qlen 1000

inet6 fe80::947f:d0ff:fe57:bc3a/64 scope link
valid_lft forever preferred_lft forever

The interface ens2f0 is part of a (openvswitch) lacp port channel (just like ens2f1), but has no ip addresses associated with it:

2: ens2f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq master ovs-system portid 3cfdfea524c0 state UP group default qlen 1000
link/ether 3c:fd:fe:a5:24:c0 brd ff:ff:ff:ff:ff:ff
inet6 fe80::3efd:feff:fea5:24c0/64 scope link
valid_lft forever preferred_lft forever
3: ens2f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq master ovs-system portid 3cfdfea524c1 state UP group default qlen 1000
link/ether 3c:fd:fe:a5:24:c1 brd ff:ff:ff:ff:ff:ff
inet6 fe80::3efd:feff:fea5:24c1/64 scope link

So, how come Ceph associate this inteface with the configured ip address?
