bonding failover not working

me_spearhead · 06-08-2012, 02:11 PM

In your /etc/modprobe.conf

Quote:

alias bond0 bonding
options bonding miimon=100 mode=active-backup

try changing the 2nd line to

Quote:

options bond0 miimon=100 mode=active-backup

and check

pantdk · 06-09-2012, 12:24 PM

alias bond0 bonding
options bonding miimon=100 mode=active-backup

options bond0 miimon=100 mode=active-backup

i made a alias hear & u didn't, rest of the config is same

i did the change as u say but no changes happen at machine, nic failover not working. now can u tell me whether u tested it at your machine & found that it work for u, or u just guess/suggest ???

I have tested it successfully on physical servers.

pantdk · 06-11-2012, 04:36 AM

o man, i know everything works fine in physical server.
did your read first page of my thread ?? it's a vm machine man
so go to the main page & read it then you can understand where i am stacking

My poor buddy,

I am aware of your environment. I just asked you to try and check the same on VM. That's how you learn things and make them work. Else we might not be here on the forum.

Happy bonding !!!!!!!!!!

hi pantdk

can we check this in oracle virtual box?

we can test it on vms once again but this time on oracle virtual box.

let me know if you have already done this.

pantdk · 08-11-2014, 11:17 PM

Hi Parkarnoor,

Oracle Virtual box is faster then Vmaware but it has it's limitation.

i haven't try anything in virtual box

You may want to try below option at /etc/modprobe.conf
fail_over_mac=1
e.g.
options bond0 miimon=100 mode=active-backup fail_over_mac=1
Although it has the downside behavior, it may solve your problem. You may want to further consult with manual for your requirement.
