network bonding problem in RHEL4 x64 ( packets losing )

Jerais · 05-23-2007, 02:57 PM

good evening

before any thing , i goolged but there is nothing

i have a problem in my network bonding and your help is appreciated

i have RHEL4 x64 with 2 NICs and i tried to create network bonding with them . the bonding ( like Fail Over) is working , but i found a strange problem .

there is a lot of packet losing when i try to ping a destination , around 15~20% .

when i stop one of the NICs , there will be NO packet losing !

there is no losing in the RHEL4 x32 .

and all them (x32 and x64) have the same configurations .

this is my modprobe.conf configuration

alias eth0 tg3
alias eth1 tg3
alias bond0 bonding
options bond0 mode=1 miimon=100

Really , your help will be appreciated

Kind Regards ,
Jerais

Are you connecting the two nics to a managed switch that can support trunking. I am not sure here but thought that was the way it works. Bonding allows doubling or more bandwidth attached to a single IP.

first , Brian many thanx for you replay

finally i solved it

what was the problem ??

i had RHEL4 x32 and x64, and network bond with the mode=0 ( Load Balancing ) before this problem , when i changed it to mode=1 ( Fault Tolerance ), and restarting the network services , i checked this file /proc/net/bonding/bond and i found it's still in the mode=0 ( This is for x64 and x32 directly changed to mode=1 ) . so i just reboot the machine and that's it !

.

BTW , is there any why to avoid system reboot ?

Glad to see you have it going. Learned something else about bonding. Knew nothing about modes.
