Solved 2 bonded nics working slowing down imaging speed
-
Working on trunk 5704 , and somehow connecting the 2 nics installed , imaging speed slows down from 5 gbps to 2 gbps or less.
I really have no clue what could be wrong , this is what i have:bond0 Link encap:Ethernet HWaddr e8:39:35:63:fa:bb inet addr:192.168.137.51 Bcast:192.168.137.255 Mask:255.255.255.0 inet6 addr: fe80::ea39:35ff:fe63:fabb/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:41730895 errors:0 dropped:7809 overruns:0 frame:0 TX packets:267044696 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4307169179 (4.3 GB) TX bytes:400834971999 (400.8 GB) em1 Link encap:Ethernet HWaddr e8:39:35:63:fa:bb UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:20472650 errors:0 dropped:0 overruns:0 frame:0 TX packets:175896638 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2338763038 (2.3 GB) TX bytes:264037377930 (264.0 GB) Interrupt:20 Memory:fe500000-fe520000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:50744 errors:0 dropped:0 overruns:0 frame:0 TX packets:50744 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18541428 (18.5 MB) TX bytes:18541428 (18.5 MB) p255p1 Link encap:Ethernet HWaddr e8:39:35:63:fa:bb UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:21258245 errors:0 dropped:0 overruns:0 frame:0 TX packets:91148058 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1968406141 (1.9 GB) TX bytes:136797594069 (136.7 GB) Interrupt:16``` Linux fog1 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux root@fog1:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

Without configuring the p255p1 and em1 the network ainºt working.(as i have no connection to server)
It works like this :
auto em1 iface em1 inet manual bond-master bond0 bond-primary em1 auto p255p1 iface p255p1 inet manual bond-master bond0 auto bond0 iface bond0 inet static bond-slaves em1 p255p1 bond-mode 2 bond-miimon 100 address 192.168.137.51 netmask 255.255.255.0 gateway 192.168.137.1``` and this is what i get : ```root@fog1:~# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: p255p1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000 link/ether e8:39:35:63:fa:bb brd ff:ff:ff:ff:ff:ff 3: em1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP group default qlen 1000 link/ether e8:39:35:63:fa:bb brd ff:ff:ff:ff:ff:ff 4: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether e8:39:35:63:fa:bb brd ff:ff:ff:ff:ff:ff inet 192.168.137.51/24 brd 192.168.137.255 scope global bond0 valid_lft forever preferred_lft forever inet6 fe80::ea39:35ff:fe63:fabb/64 scope link tentative dadfailed valid_lft forever preferred_lft forever``` -

@mitzayapa I agree that looks reasonable. Restart the network service and see what you have with
ip addr showI do have to say I’ve only seen where they bond like adapters. This should work but now you have two network drivers loaded. Again not a problem, just not standard.

@mitzayapa Sorry I was reading fast before I started my commute into work. I read p255p1 as your primary interface. I thought it was strange, but I’ve seen some pretty strange stuff in the last few days.
As for the bonding, what you have is correct, you still need to assign the normal IP address stuff to the bond0 interface.
At the very least these:
address 192.168.137.51 netmask 255.255.255.0 gateway 192.168.137.1 -
I used round robin, it gave both speed and resilience, however that was on an unmanaged switch.
-
The p255p is the second NIC I added to the server.
em1 - built in
p255p - 1gigabit ethernet cardauto em1 iface em1 inet manual bond-master bond0 bond-primary em1 auto p255p1 iface p255p1 inet manual bond-master bond0 auto bond0 iface bond0 inet static bond-slaves em1 p255p1 bond-mode 2 bond-miimon 100 ... -> is there missing something or thats all ? -
@Sebastian-Roth In some of the ubuntu examples they always use bond-slaves none. Not sure why. I would agree with your setting.
As for the primary, I still think I would use the onboard nic for primary, but again I don’t know what a p255p network interface is. Also if the xor mode (bond mode 2) (not really intelligent but fast) isn’t properly sharing the bandwidth during 3 or more installs at the same time, I would switch to bond-mode 5 or setup lacp on the switch and use bond-mode 4.

I’d suggest this config:
auto em1 iface em1 inet manual bond-master bond0 bond-primary em1 auto p255p1 iface p255p1 inet manual bond-master bond0 auto bond0 iface bond0 inet static bond-slaves em1 p255p1 bond-mode 2 bond-miimon 100 ...Please help us build the FOG community with everyone involved.

Whould any of you be kind and paste a corrected interfaces file for my configuration?
-
True , there´s no eth1 device in my config. Just delete it ?
-
And why
bond-primary em1 eth1?? You don’t have eth1 as ifconfig shows. -
Well, I think this line is in error
bond-primary em1 p255p1
Since you already have that defined for em1 or I would only select one, probably the internal one for primary.Secondly I think I would use bond mode 5 or if you have access to the switch setup LACP mode.
Did you deploy only one client in the test above or more than one? The packets transmitted seem to indicate the second nic is not being used. If you had only two actors in the conversation I would understand the packet mismatch.
-
em1 is the builtin NIC , p255p1 is the one I added.
Ive tested it for some days now , with more than one client , so can u tell me what should i remove/add to my config ?
From the last reboot the server was at first connected through buildin NIC then after a few hours ive connected the second NIC -
The os is Linux fog1 3.19.0-25-generic #26~14.04.1-Ubuntu , i deploy up to 12 pc´s at once what; i olso have dnsmasq enabled.
Whats missing from my config ?
-
Ok, I see from the kernel you are using ubuntu.
I also noticed that all of your network traffic is passing over p255p1 what is that network adapter?
-
I have seen slighlty slower speeds (between two actors) when using bonding, because when you enable bonding you also add a bunch of code between the OS and the network interface. But 50% loss is a bit much.
Just looking at your bonding configuration it looks like there are a few things missing. What OS are you using here?
Also what is your idea for using bonding? How many devices will you deploy at once?
-
@mitzayapa Hi, have you configured your switch to enable LACP ?
I use it on a debian 8 (in vmware esxi 5.5) with that interfaces config :
auto bond0 iface bond0 inet static address 172.20.0.4 netmask 255.255.0.0 gateway 172.20.1.50 slaves eth0 eth1 bond_mode balance-alb bond_miimon 100 bond_downdelay 200 bond_updelay 200
