Re: [ovirt-users] bonding mode-alb

[Demeter Tibor]

Dear Luca,

I've created a config with two 16 port 10GBe switches,those does not connected 
to each other. 
I have 4 hosts and 1 storage host. I don't know why, but I can't ping from all 
of host to all of hosts. 
For example I can ping from .1 to .2 but not .3! From .3 I can ping .4 but 
don't .1 :)
I don't know the cables how is connected to the switch, but I'm sure every host 
connected to switches whit two inferface (one-to-one)

Thanks!

Regards,
Tibor

 Dear members,

 I would like to use two switch to make high-availability network

 Unfortunately, these switches does not support 802.3.ad lacp, (really I
 can't stack them)  but I've read about mode-alb and mode-tlb bonding modes.
 I know,these modes are available in ovirt, but how is work that? Also how
 is safe? Are there for HA or for load balance?

 I've read some forums, where does not recommended these modes to use in
 ovirt. What is the truths?
 I would like to use only for storage-traffic, it will be separated from

Hi Demeter,

i don't know how the switch setup is done here, but as far as i know
they aren't stacked through interconnect.

Sorry for the very late reply.. 

I want to try out now your mentions. 
Should I make an interconnect the two switches in active/backup mode?

Re: [ovirt-users] bonding mode-alb

[Luca 'remix_tj' Lorenzetto]

Hi,

If you're looking at a simple ha bonding setup, why not using active-backup
(mode 1)?

We're using it in almost all our setups and switches toin backup interface
in 100ms when a link down is detected (Setting miimon=100).

Doesn't aggregate bandwidth but is a very good solution for high
availability whwn you can't configure lacp or a portchannel on switch side.

Re: [ovirt-users] bonding mode-alb

[Demeter Tibor]

Hi, 

Thanks for the answers. 

In this case the only question is: what is better for me? Mode 5 or 6? 
In which modes how is fast the switching? 

Until now I've use 802.3ad lacp on our old cluster. I did some tests and it was 
very fast. I know it is not same, but mode 5 or 6 how is safe? 
Thanks

"Important: Modes 1, 2, 3, and 4 support both virtual machine (bridged) and
non-virtual machine (bridgeless) network types. Modes 0, 5 and 6 support
non-virtual machine (bridgeless) networks only.¨

So both tlb (mode 5) or alb (mode 6) are fine only if you use them just for
the storage access but not for VMs.

No personal experience, but I would stay with what offcial docs say
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/administration_guide/sect-hosts_and_networking#sect-Bonds

As you are writing about NFS storage, mode 5 and 6 should be supported
(non-virtual machine (bridgeless) networks)

Do you have any pointer about no-go recommendations?

Re: [ovirt-users] bonding mode-alb

[FERNANDO FREDIANI]

Hello

If you have 10Gb ports you hardly need to use these aggregation in order 
to have more bandwidth. 10Gb is enough for A LOT of things. Just use 
bonding mode=1 (active/backup) if your switches don't support stacking.


Doing mode-tlb and alb is not always straight forward as mode 1 or mode 4.

I've read some forums, where does not recommended these modes to use in ovirt. 
What is the truths?
