[Users] FW: ovirt 3.2.1 custom bonding options

Wed Jun 26 05:56:09 UTC 2013

Hi,

for all oVirt users who wants to run their nodes in balance-rr mode:
Go to "Network Interfaces"
--> "Setup Host Networks"

Edit the bond interface you want to change
--> "Bonding mode"--> "Custom:"
--> "Custom mode" --> mode=0 miimon=100 (depends on your scenario)

Make sure you did activate the checkbox "Save network configuration",
press OK.

Verify on node-console via cat /proc/net/bonding/bond[n]:

Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: em1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: d4:ae:52:e8:26:a1
Slave queue ID: 0

Slave Interface: em2
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: d4:ae:52:e8:26:a2
Slave queue ID: 0

Slave Interface: em3
MII Status: up
Speed: 1000 Mbps

Very useful to power up network throughput for oVirt mgmt. network with single 1GBit connections only.

Cheers,
Sven.

Hi,

just have a tiny question, regarding bonding & custom mode:
If I want to run a bond in mode 2 with miimon=100,
how needs the custom text field look like:
BONDING_OPTS="miimon=100 mode=0" ?

(would be equivalent to ifcfg config file)

Thanks in advance!

Cheers,
Sven.
