Bonding network + iDRAC fencing device

[djahida]

Hi,

I try to configure a proxmox cluster HA (+Quorurm + fencing) and bonding network.

For the bonding network below my interface configuration file

# network interface settings
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

iface eth3 inet manual

auto eth2
iface eth2 inet static
address 192.168.x.x
netmask 255.255.255.0

auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode active-backup

auto vmbr0
iface vmbr0 inet static
address 192.168.y.y
netmask 255.255.255.0
gateway 192.168.z.z
network X.X.X.X
bridge_ports bond0
bridge_stp off
bridge_fd 0
dns-nameservers 8.8.8.8

For the part of fencing, I configure my iDRAC6 express with IPMI over Lan
But when I ping the idrac interface, i have a duplicate packets. so my fence dont work.

Do you have any idea about this problem
Thanks

If the iDRAC has its own port, you can bond, else you can't.

Thanks Lokytech
The iDRAC has not its own port
But why I can not bond?

As it seems you have 4 nics you can make a bond of 2 or 3 nics. One nic has to be reserved for idrac since idrac needs an assigned IP directly to the interface. In your case this means assigning idrac to eth2. If idrac can only be assigned to eth0 then make your bond using eth1 and eth2.

Thanks for the reply mir.
I want to configure the idrac to use eth0 and eth1, and use the same interfaces as bonding
But I dont know if it's correct.

 

[mir]

You cannot bind idrac to a bond. period.

Thank you mir
I found mutliple mode bonding: active-backup, 803.ad,....
To ensure the load balancing and increase the bandwidth, what is the appropiate mode?
And what about the switch? there is any modification to do?

 

[mir]

802.3ad requires support from the switch. The rest does not require support from the switch. IMHO. the only mode to choose is 802.3ad.
