Hello,
on a 2 nodes cluster in 4.1.6 I have this situation.
Every node has 3 bonds, each one composed by 2 network adapters and each
one of type mode=4
(actually in setup networks I have configured custom and then the value:
"mode=4 miimon=100"
)
At this moment only one of the servers has access to FC storage, while the
other is currently on maintenance.
On 2 of the 3 bonds of the active server I get an exclamation point in
"Network Interfaces" subtab with this mouseover popup
Bond is in link aggregation mode (mode 4), but no partner mac has been
reported for it
What is the exact meaning of this message? Do I have to care about (I think
so..)?
What should I report to network guys?
Eg, one of these two warning bonds status is:

Also, the other node (that is currently in maintenance) shows one of the 2
interfaces of bond2 (ens2f2) as down (red arrow) but on the host
# ip link show ens2f2
6: ens2f2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master
bond2 state UP mode DEFAULT qlen 1000

Does this depend on the host being in maintenance?
Perhaps when a host is in maintenance, the warnings on it are not
checked/updated again from engine?
Thanks in advance,
Gianluca
