As you have enabled bonding feature that means 50% of transfer has a speed 10MB/s.

So I assume it is a wire issue. to valid this, swap the wires between eth0 and eth1. I expect speed transfer to be 10MB/s on eth0
In this case you will have to change it.

Otherwise disable bonding feature and use only eth0 port


Hi Jocko
i don't know why bonding is active. i swap the wire and this is the result:
Code: Select all
[root@LaCie-5big ~]# ethtool eth0
Settings for eth0:
   Supported ports: [ ]
   Supported link modes:   
   Supports auto-negotiation: No
   Advertised link modes:  Not reported
   Advertised pause frame use: No
   Advertised auto-negotiation: No
   Speed: 1000Mb/s
   Duplex: Full
   Port: MII
   PHYAD: 8
   Transceiver: internal
   Auto-negotiation: off
   Link detected: no
[root@LaCie-5big ~]# ethtool eth1
Settings for eth1:
   Supported ports: [ ]
   Supported link modes:   
   Supports auto-negotiation: No
   Advertised link modes:  Not reported
   Advertised pause frame use: No
   Advertised auto-negotiation: No
   Speed: 1000Mb/s
   Duplex: Full
   Port: MII
   PHYAD: 0
   Transceiver: internal
   Auto-negotiation: off
   Link detected: yes

Now, both ports show 1000Mb/s and Full Duplex.

I forgot to mention that just one port is connected with router/switch.

My question is: bonding in this sort of configuration, it makes sense?
What and when we need it?

if you use only one cable only that particular interface will be used, 1000 mb/s and full duplex is the correct mode.
Funny is that all auto negotiation options are switched off.
In your post with output from ifconfig you can see that only traffic has been sent and received via eth0. So when you have a cable only on eth0 it doesn't matter what the settings of eth0 will be either if bonding is enabled.

The settings of your network interface seems to be ok, there must be another reason for the slow transfer.
Did you measure how slow it is. How mich time does a file bigger then 1 GB takes to transfer (read and write ?)

Yes, on my Mac i use a little tools named iStatPro. This, monitoring in real time the transfer rate and from Mac and Lacie i have 30Mb/s and more. In the last test, transfer collapse to 4Mb/s or minus, and never exceed 14 MB (for few seconds)

On my LAN i have another NAS (a QNAP) and transfer from Mac and Qnap is constantly more than 80Mb/s :-D
This is why i asked.

Then it could be a driver issue causing communcation problems between lacie nas and client or a problem with the samba server or the nas is busy with another application running at same time. You could use the "top" command to see what keeps the nas busy and consumes cpu capacity.
Further ethtool command has many option to study network issues, I suggest you try google to learn more

thanks! For now (just swap the wire from one port to another) the transfer rate is around 25 Mb/s. Much better than yesterday.
I think that another factor is that the volume target on Lacie is a Raid5, on Qnap is Raid 0.
