[Users] Network issues - Bonding

[Assaf Muller]

If you ifdown bond4 then ifup it, does the bond mode properly update
to bond mode 1? If not, it sounds like an initscripts or bonding module bug.

Hello All,

A little bit ago I wrote an email about network issues I was having.

I found the problem...

On the VM host, I had a bond set up between two network interfaces.  The
bond mode was set to mode 1 (active/passive).

However when I look at the bond on the box, I get this:

[root at node02 bonding]# cat bond4
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

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

Slave Interface: em2
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: d4:ae:52:6d:c8:cc
Slave queue ID: 0

Slave Interface: em3
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: d4:ae:52:6d:c8:ce
Slave queue ID: 0

Somehow, the OS is not setting the bonding mode right.  I verified that
it was set to mode 1 in /etc/sysconfig/network-scripts/ifcfe-bond4

When I take the bond away, the host network works perfectly on both of
the formerly bonded interfaces.

So again, if anyone has any ideas, I'm open to suggestions.

Thanks,

Dan
