Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

Hello, I?m trying to configure a CentOS 7 server to act as a host for a bunch of virtual servers (KVM). I have an 802.3ad bonded Ethernet connected to the server with a bunch of tagged VLANs. I want to be able to build a bridge interface on the server for each VLAN and then attach that to the bond interface and the virtual clients. I also want to attach a host interface to one of the VLANs

Are these messages benign and to be ignored?

Hi, We have a Dell server with 4 Ethernet interface. I would to aggregate them in a bond. Everything work but the default gateway doesn?t work on the ? bond0 ? interface and I have no links.

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

Hi all, Don't mean to double post as I sent this to the general Centos list. But, does any one have 802.3ad (mode 4) working on there Centos6 KVM setup? This would be a bridge+bond setup of course. If not possible, would I still bond the interfaces on the switch and then bond them in the guest rather then from within the hypervisor? - aurf

*Hi all, I''m not quiet sure the most reasonable way to dealing with bonding on xenserver. My configuration is as follow. It was ok if i do nothing, but When I tried to ''service network restart'', the bond is break. Then, /proc/net/bonding/pbond: Slave Interface: eth0 eth1 was down bonding MII status: down My questions are: how to deal with this situation? how to avoid

Hi all, I've setup a ethernet bond on my centos 5.6 server , when i do a reboot the bond does come up but cleared all the slaves and i've to manually re-add them with ifenslave. does anyone know a solution to this? am i missing something? offcourse i can add it to my rc.local but there must be a more elegant way. please see my configs below Thanks, Wessel ifcfg-bond0: DEVICE=bond0

Hi, I am currently struggling with the right way to configure a bonding device via kickstart (via PXE). I am installing servers which have "eno" network interfaces. Instead of the expected bonding device with two active slaves (bonding mode is balance-alb), I get a bonding device with only one active slave and an independent, non-bonded network device. Also the bonding device

I have a machine I just deployed w/ tg3 interfaces, I have setup bonding on this same line of server (HP DL380 G4) a million times. I saw there were changes recently to how you configure a bond and have my setup configured according to: http://kbase.redhat.com/faq/docs/DOC-7431 The HP switch has a LACP trunk defined on the two ports. Problem is, when rebooting, I need to issue a `service network

This is happening with the Centos7-armv7 image 1804, but I was wondering if it is a broader C7 issue. My image has only 2 ifcfg files:? ifcfg-l0 and -link.? 'ip a' is listing the ethernet as eth0.? ifcfg-link has contains: DEVICE=link BOOTPROTO=dhcp ONBOOT=on I then used nmcli to create my ifcfg-eth0 nmcli con delete eth0 nmcli con add type ethernet con-name eth0 ifname eth0 ip4

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the

I'm running into a situation where a bogus bonded interface named "bond0" is being created, in addition to the desired "bond2" interface. Can anyone confirm this? Anyone know why it's happening or what I do to get rid of it? I wanted to start my numbering scheme at 2 instead of 0, which I didn't think would be a problem. As you can see, I have no reference

Hi all, we are testing CentOS 7 in order to migrate from Scientific Linux 6 / CentOS 6 and we are facing an issue with the network. Trying to configure network with teaming in activebackup mode or also with bonding in mode=1 (active backup as well) we see many RX dropped packets in the bond0 interface (around 10% of the total), 100% RX drops in the backup interface and 0% in the active interface.

Hi, I ran gemu-img on a VM thinking it was down but in fact it was live. I rebooted the VM and it does show the added space after running pv/lv etc to resize the disk, also the KVM server if you will, also shows the correct new size of that particular VMs raw file via du. However the virtual machine manager still shows the disk size of that VM as being before the resize. Is there a way that I

Hi all, I just noticed that my two nics that are bonded via mode 0 are showing the same mac addy in ifconfig. Is this normal? In syslog I keep getting; kernel: pbond0: received packet with own address as source address Some guidance is appreciated before I dive in and troubleshoot. If I don't list the mac addy in my ifcfg-th# files, only one of the 2 nic comes up during boot.

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot.
