Kimmax Host is Proxmox, guests are mostly Ubuntu nowadays. Made that mistake with Arch earlier Coincidentally, the reason why I moved away from it in favor of Ubuntu was a similar systemd shenanigan in which systemd broke systemd-networkd on the guest effectively bringing it offline due to incompatibility with AppArmor.

LAG Configuration: which hash mode to use for linux bond.

It only got solved after a full month, and only worked for new installments, not existing ones. Condor yeah I know about the arch issues, hence the question. Actually - what mode is the bond in? Just active-backup stuff, or some link aggregation too?

Also make sure you set your physical interfaces to manual, I totally got fucked by that before. Kimmax currently it's in Box somewhat supports it this is a home lab. It's configured to have the bond as the bridge port for vmbr0 - the bond on its own didn't work too well. Condor are you absolutely sure the Fritzbox supports lacp?

That would be a new one for me. I have next gen,and didn't find anything in the GUI. So not great in terms of redundancy. And judging by the Blinkenlights, both interfaces seem to be in use too.With my two new servers prepared I set about installing the latest version of Proxmox 5. I did the installation via the iDrac console over the network and it was very nice to be able to install the OS from my desk without needing to bother with pulling out a screen, keyboard and mouse.

The installation of Proxmox is very straight forward and although it did not allow me to configure my desired network configuration during the installation it does allow for various storage options. The Proxmox wiki is very comprehensive and I do recommend reading it before starting as there are a number of things to consider when deploying a hypervisor.

Personally I prefer to use OpenVSwitch for this and installed it as follows: apt -y install openvswitch-switch. With the networking configured I proceeded to configure the update repositories, update the servers and install my usual utilities:. The newer versions of Proxmox make the configuration of a cluster very simple and everything can be done in the web UI.

One of the newer features in Proxmox is support for a Corosync QDevice. A long outstanding issue with running two node Proxmox clusters is that in the event of a vote, it is possible for there to be a tie. This can cause multiple issues and while it would be possible to add a third Proxmox server without any VMs or Containers, simply to prevent this situation it is rather overkill. A QDevice is simply a lightweight process running on another separate server or virtual machine that adds a vote to one of the nodes so that in the event of a vote the is no tie.

I chose Ubuntu This allows the Proxmox servers to ssh into the QDevice server without needing to enable password based root ssh logins. Each node in the Proxmox server then needed the QDevice package which can be installed as follows: apt -y install corosync-qdevice.

With each node prepared I added the QDevice as follows: pvecm qdevice setup There is some output of this command which I failed to capture but it should be very obvious if anything went wrong. At this point I have a fully functional two node Proxmox cluster running the vast majority of my virtual machines and containers.

I finished things off by copying the distro script from my LibreNMS server, installing and configurating snmpd and adding the servers to my LibreNMS monitoring.

However this post is already rather long and that would be getting quite out of scope to go into in detail. At some point later in the year I plan to add a third node to this new cluster which will be based on different hardware, specifically to fulfil these requirements.

More on that in a later post. Installing Proxmox With my two new servers prepared I set about installing the latest version of Proxmox 5. Cluster Configuration The newer versions of Proxmox make the configuration of a cluster very simple and everything can be done in the web UI. Once complete, the second node can be joined in the same location using the join information.

Everything else is taken care of and at this point I had a functioning two node cluster. I was then able to verify that my QDevice was in use and that my cluster had quorum as follows: At this point I have a fully functional two node Proxmox cluster running the vast majority of my virtual machines and containers.Got a bit of a strange problem. I have a machine running Proxmox 5. Obviously, the switch is managed and supports LACP and I have configured a trunk setup on the switch for the 4 ports.

Over the weekend I installed netdata on the Proxmox host, and now I'm getting continual alarms about packet loss on bond0 the 4 bonded NICs. I'm a little perplexed as to why. Interface output below, you'll note that the bridge interface to the VMs has no dropped packets, it's happening only on bond0 and it's slaves. Initially suspecting it was some kind of buffer issue, I did some tweaking in sysctl to make sure the buffer sizes were adequate.

Hash Distribution

Any ideas on what I should try next? I'm starting to think that there is something I don't understand about the NIC teaming. As I said, everything seems to work fine but it concerns me a little about the high packet loss. Other machines on the network that are connected to the switch do not have this issue the 5th NIC on the machine is fine, too. The Kernel then sees these packets as duplicates and drops those apart from the first arriving one of course.

While this is of course not elegant, it seems not to create problems in real life. You can verify if it is this effect by sending many broadcast packets on purpose and checking if this lines up with the drop statistics. Everything seems to work fine, or so I thought. Eugen Rieck Eugen Rieck Hmm, I did suspect something like this.

That would make sense from the math, being that there's basically the same number of dropped packets across each NIC. Is there a way to tell exactly what's getting dropped? I ran dropwatch on the machine, but I really couldn't interpret the output well enough to conclude one way or the other.

My diagnostics were rather basic: Increase rate of broadcast packets and see, if drop rate increases acordingly. I didn't investigate much further, as everything was working fine with no loss of payload packets.

Check the bandwidth of LACP bond between TrueNAS and PROXMOX Server

I did some more digging around. I wrote a script to fire out a whole bunch of broadcast packets. It didn't seem to increase the rate of dropped packets, though. This is representative of what I've been seeing.Lately we've setup a new Proxmox 4.

For this we upgraded our former ESXi 5. Also we don't wanted to use the internal NICs anymore as they're shared with the internal iDRAC and to have only one kind of hardware being used so Intel-only. Sadly one cannot bond bonds in Linux Why not, actually? If you know it, i'd like to see an answer in the comments! This idea being abandoned, we've gone through all the available bonding modes and while reading through mode 5 our eyes started to shine while they shined brighter when we reached mode 6.

This one actually seemed to be the choice to go for us. It does not need any special switch configuration and the switches can be totally separate from each other despite having to be configured the same from a VLAN perspective but that's easy on a managed Layer 2 switch.

As you can see, we now have one Linux Bonding over both cards to both switches using a Bond with Mode 6. Now that we have a working network setup we can create VLANs and then create the vmbr devices on top which can be used by the Virtual-Machines later. For more clarification of the configuration shown here you have to know that we configured the VLANs on the switches as follows.

On each switch there are several VLANs. After that all other VLANs i only added one more, so the config is short enough to get the idea are tagged. This virtual interface can now get VLAN tagged packages from the bond0 raw device.

You can add more tagged VLANs according to your needs. You can name vmbr like you want. Also you have to take care that you take the right ethX devices in your configuration later.

You can check that by comparing the MAC-addresses for example. In our case the NICs where really sorted correctly from the start which made it a bit easier. You may also want to reboot once after finishing the configuration to make sure the config works correctly.

Our HA-Tests also showed that the config works really great. Depending on if a connection is currently up using a slave interface which you cut this moment it needs none to 3 pings in our tests for the connection being back and while using a TCP-based Test like SSH, the connection doesn't even go down. This guide should also work for older and newer Proxmox instances as well as any other Linux distribution. While Proxmox 5. You have to try that out first, what a naming they got.

For the upgrade we nuno bettencourt home to have more bandwith while still preserving High-Availablility. So our final network diagram with bonding mode 6 looked as follows: As you can see, we now have one Linux Bonding over both cards to both switches using a Bond with Mode 6. The config now continues like this: auto bond0. Conclusion This guide should also work for older and newer Proxmox instances as well as any other Linux distribution.Have been using NIC teaming for many years with success on a R2 similar hardware system, one generation older, and while I initially had some of the "network startup woes" where it was fine until a reboot, but then team wouldn't come online This new system, I have been running as a lab machine, but need the bandwidth, and I'd really like it to work too!

Have installed a headlessto run the HyperV on, and while initial NIC config was direct and automatic, once I created the Team and added the 4 nics to it, and moved the cables over to the 4 ports they should be in, no joy. My team config is set to: includ the 4 names, lacp mode, dynamic, and fast.

Doing this via powershell now of course, at the console, so open to any commands, tweaks, etc. Attachments: Up to 10 attachments including images can be used with a maximum of 3.

Moved the physical box into a live room, where there is a Cisco SG smart switch, presently doing NIC teaming with a R2 box for a number of years now. Created a second LACP trunk, assigned some ports, and ran haphazard cables from the server box to this switch. It would seem that Windows Server and perhaps all of them before it too? Good to hear that you have solved this issue by yourself.

In addition, thanks for sharing your solution in the forum as it would be helpful to anyone who encounters similar issues.

Thanks Candy, your video link helped me bmw 93fd find the newest GUI options, and make this process much simpler.

As a headless server, I had been working through powershell, where a gui lets you flip things back and forth and try ready examples, for sure!! I have also since original posting, changed out the drivers for the NICs, for drivers from Dell, specifically for these network cards listed above. Not sure if that helps or hinders, happy to listen to advice on that.

There was commentary from others elsewhere that suggested the MS default drivers for these cards has "issues". But that didn't help either. I can confirm that the switch is set for 4 ports of LACP, and I am presently using three of them, while keeping the 4th nic separate from the team, to continue to have remote access to the server.

Switch is a DLink, and the ports are set to "active".For many years, most servers have come with several network interfaces, but for most purposes, albeit with some noteable exceptions, the available bandwidth of the network interface has not often been the limiting factor on the performance of my services.

Therefore it has been common to only use a single network interface on each server. However, now I have a pattern that require lots of bandwidth, and it seems that it would be useful to take advantage of all those spare NICs. Virtual machine hosts often require lots of bandwidth since there are potentially many services funnelled through the host's NIC so 4Gbps sounds much more appealing that 1Gbps.

Fortunately, linux networking is powerful and conveniently allows for joining several interfaces into a single pipe. Linux refers to this as a bondbut you might also see the word trunk used this way, although trunking often refers to the practice of making several VLANs available on a single interface.

The second part of this article briefly explains how to modify the bonded setup to allow for bridged networking. The basic idea is to create a virtual network interface as a bond, configure it with the IP addressing information that we want, but no physical interfaces, and then add the physical interfaces to the bond.

Here's a diagram:. See the kernel bond documentation for details. There are number of different possibilities for the value of modeas documented in the linux kernel's bond documentation. Mode 4 is Another likely possibility is mode 6 balance-alb, Adaptive Load Balancing which does not require special switch support.

Before I do anything on Proxmox, I do this first…

That second line options Modify the bond to add it to the bridge. Modify the physical interface s configs to add them to the bond. Lots of managed switches support this, including models from Cisco, such as theand even some? Dell PowerConnect models. Comments welcome. Actions: Security. Bonded and Bridged Networking for Virtualization Hosts For many years, most servers have come with several network interfaces, but for most purposes, albeit with some noteable exceptions, the available bandwidth of the network interface has not often been the limiting factor on the performance of my services.

The first part of this article discusses and demonstrates bonding network interfaces. How to simply use 2 network interfaces in a single bond The basic idea is to create a virtual network interface as a bond, configure it with the IP addressing information that we want, but no physical interfaces, and then add the physical interfaces to the bond.

Configuring the bond interface Here is one possible setup, there are others. Then repeat for additional NICs ifcfg-ethN. Using LACPConfigure bond interface on the server and connect both eth1 and eth2 to this bond, refer to Linux Network bonding — setup guide - Cloudibee's Notes Make sure you use bond mode 0 or 2. You cannot configure on VM with bond and another VM with regular one port connectivity - It will not work basic networking. Mellanox Technologies. You might just need to refresh it.

Mellanox Interconnect Community. Information Title. URL Name. It is not possible to do it within the hypervisor in such case. Setup Host Configuration 1. Configure IP address on the bond interface.

Any idea? Config Juniper Switch: ->> to working Proxmox Server 1 set interfaces ge-0/0/14 ether-options ad. Bonding (also called NIC teaming or Link Aggregation) is a technique for binding multiple NIC's to a single network device.

It is possible to. Hi I'm having a really hard time trying to get the network setup on Proxmox despite looking at all of the forums and tweaks I've been doing. Hi, In my proxmox network configuration, I have 4 LACP bonded interface as follows.

Martin Seener

bond0 -> for management bond1 -> for cluster network. My configuration: Proxmox machine has 7 ethernet ports, used as: 1x - Management port 1x - WAN port x4 - LACP bond to Tp-Link managed switch x1 - Used as. I would like to configure my machines to have one bond with all six nics and put three vlans on top. I currently do not have any vlan. Hello, I have a server that I am setting up in a Data center, I installed proxmox VE, but for them to allow me to access to the network.

I have configured a 2Gbps LACP bond on my Netgear GST managed switch and is also setup as a VLAN trunk with it's PVID (native VLAN) on 8 so it can. I'm having some trouble getting lacp working between my proxmox node and my cisco s switch.

The node has no network connection (trying. tdceurope.eu › GZnIBKi4 › proxmoxlacp-bridge. I need to configure Proxmox 5.x with the following. Bond of 2 interfaces using LACP Bridge off Bond0, with IP on VLAN (/24).

In Linux, bond-mode 4 is ad, not LACP. ad is the teaming protocol, while LACP is the process of making those physical links into one. In order to setup bonds, ProxMox offers the functionality via WebUI under system->network -> create->linux bond. You can select bond members. I've done the LACP configuration on the GS and used the PVE gui for create a Linux Bond with slaves "eth2 eth3".

When i restart the server. on this example # Has the server's public IP iface bond0 inet dhcp bond-slaves ens33f0 ens33f1 bond-miimon bond-mode ad post-up. We will now see network bonding in our cluster. There are several types of bonding options available. But only balance-rr, active-backup, and LACP (ad). Adding the Open vSwitch bond Like the Linux bridge, we can create various Open vSwitch bond interfaces.

In this example, we are going to create the LACP. i have just configured an bond between two 10Gig ports in Proxmox server and connected them to the TrueNAS.

now i want to verify the link. Out first idea was to use 2 LACP-Bondings from each Dual-Port NIC to stata boottest switch and use a third active-backup bond over the 2 LACP-Bonds. one LACP bond in proxmox which is a member of a VLAN aware bridge; the OPNsense VM would only get two network cards (the two mentioned bridges) and configure.
