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: # cat /proc/net/bonding/bond2 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: slow Min links: 0 Aggregator selection policy (ad_select): stable System priority: 65535 System MAC address: 48:df:37:0c:7f:5a Active Aggregator Info: Aggregator ID: 5 Number of ports: 2 Actor Key: 9 Partner Key: 6 Partner Mac Address: b8:38:61:9c:75:80 Slave Interface: ens2f2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 2 Permanent HW addr: 48:df:37:0c:7f:5a Slave queue ID: 0 Aggregator ID: 5 Actor Churn State: none Partner Churn State: none Actor Churned Count: 2 Partner Churned Count: 3 details actor lacp pdu: system priority: 65535 system mac address: 48:df:37:0c:7f:5a port key: 9 port priority: 255 port number: 1 port state: 61 details partner lacp pdu: system priority: 32768 system mac address: b8:38:61:9c:75:80 oper key: 6 port priority: 32768 port number: 293 port state: 61 Slave Interface: ens2f3 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 2 Permanent HW addr: 48:df:37:0c:7f:5b Slave queue ID: 0 Aggregator ID: 5 Actor Churn State: none Partner Churn State: none Actor Churned Count: 0 Partner Churned Count: 3 details actor lacp pdu: system priority: 65535 system mac address: 48:df:37:0c:7f:5a port key: 9 port priority: 255 port number: 2 port state: 61 details partner lacp pdu: system priority: 32768 system mac address: b8:38:61:9c:75:80 oper key: 6 port priority: 32768 port number: 549 port state: 61 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 link/ether 48:df:37:0c:85:4e brd ff:ff:ff:ff:ff:ff # 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
