LAGG does not seem to work in any mode.

[acidrop]

Hello,

This is my first post and first try to install Nas4Free on a HP Microserver N54L with 3 x 2Tb WD Reds in ZFS raid-z1.ZFS work as excepected, no problems at all.
The only point where I am stuck is trying to create a LAGG (bond two ethernet cards) and put it in roundrobin mode(tried almost all modes with no success).
HP Microserver has an onboard card and I have added another one (Intel).Below is some info about the nics:

Code: Select all

        inet 127.0.0.1 netmask 0xff000000
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

I followed this post to configure the LAGG (link viewtopic.php?f=55&t=357).
I selected roundrobin/loadbalance/failover modes but no one of them seems to work.
LACP is not supported by my switch so that is not an option.
One thing I have noticed is that when I create the LAGG interface and put as slaves my 2 nics and then reboot, all 3 interfaces now has the same MAC address. Is this normal?
Whenever I try to ping from console to any computer outside I get as response:

ping: sendto: Device busy

I've tested also this on a virtual machine with 2 vnics and the problem occurs there too.
Can you please assist with this? I have enough experience on Linux but not so on FreeBSD.

thank you

What version did you use?
If LAGG is configured, ifconfig shows like this:

Code: Select all

Also Welcome message is like this:

Welcome to NAS4Free!
    NAS4Free: 9.3.0.1 (revision 1126)

        LAN Network IPv4 Address: 172.18.0.165
        LAN Network Interface:    lagg0
        OPT1  -> em0 (OPT1)
        OPT2  -> em1 (OPT2)

I think OPT1/OPT2 is not needed.

Version is Nas4Free 9.2.0.1.972 x64.
I noticed in your configuration that all your interfaces(em0,em1,lagg0) share the same mac address (08:00:27:b3:f9:9d), the same happens to my setup.

Welcome message is identical with yours(this is a screenshot from a vm where I'm testing N4F).



LAGG interface details (this is a screenshot from a vm where I'm testing N4F):



Although the settings above are on vm the same situation exists on physical box (n54l).

Just because I am curious and I formerly also played withh LAGG and skipped it again:
why do you need it and what do you want to achieve with it?

Unless you you don't have a managed switch, it usually does not make too much sense.

[acidrop]

This nas box will be dedicated for backups, so what I want to achieve is maximum throughput by combining the speed of 2 gigabit nics in roundrobin manner.I know it won't achieve 2gbit speed, but in tests I've done on linux bonding in same setup it peaks around 1.5gbit with simultaneous backup jobs.
