Channel Bonding Module

[Nobody's Hero]

I have a small kernel built in RH9. Can someone tell me how I can tell if I have the Channel Bonding Module installed? This is needed for load balancing.

[Alexander Chuzhoy]

do
grep BONDING config-kernelversion


where config version is the version of the kernel.
Of course if you have the config file saved.
Try to find it under /boot or do a search on your file system.

OK, Here is what I have,


does this mean I can go ahead and start to config my bonding addresses. This means that I have the module ready to go in the kernel?

# grep BOND /boot/config-2.4.20-8
CONFIG_BONDING=m
CONFIG_WINBOND_840=m
CONFIG_WINBOND_FIR=m

[Alexander Chuzhoy]

try this command
insmod bonding


then lsmod
If the previous command didn't give you any error and in the list of lsmod you see bonding -it means that the module is currently loaded to the kernel

Thanks for all the help.

I have it running OK now. Using 2 nics bonded to bond0. However, I am not seeing faster times through NFS.

I nfs'd a file yesterday @2.1 Gbytes it took 16 minutes.

Today, using a bonded NIC, @2.1 Gbytes took nearly the same, a little faster.

Both test copies are via NFS to the NAS running Linux.

Why dont I see the copy complete in half the time that it took on one nic connection? I expected to see the time drop in 1/2 when I went to a dual nic.

I don't think that the NIC is the bottleneck here.
You have to take in mind also other factors:
Disk speed,controller,etc.
