similar to: using ip address on bonded channels in a cluster

I've got a Centos 5.8 box that I use for testing Xen VMs. I'm trying to setup some Centos 6.2 hosts in a high availability situation. I've tried the pacemaker route and couldn't get the connection established, so thought I'd try the RH-preferred methods. Mind you, all of these VMs are on the same host. Using Conga, it seems that I need some sort of fencing device, which

Since I upgraded from 4.4 to 4.5 my system which has 2 sets of ALB bonded interfaces hangs on shutdown while doing an ifdown on these interfaces. Has anyone else seen this issue with 4.5 and bonding?

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

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

Hi, I've using linux bonding in active-backup mode to combine two pairs of GigE NICs (eth0/eth1, eth2/eth3) into two logical bonds (bond0/bond1). All is working fine. However, I would like to specify a primary interface for each bond. This means I need to specify different options to the bonding module for each bond. I have tried every conceivable incantation of options and cannot get the

hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*

I am not sure this is the proper forum for this question, feel free to redirect me if you like to the correct place. I have the following setup: vmware esxi 2 CentOS 5.3 servers (vmware virtual hosts) these 2 servers are running conga(luci, ricci) and the rest of the cluster suite with a simple IP address setup to failover for testing. My problem comes in when I need to setup fencing for

Hi all, I'm happy to announce a new tutorial! https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial This tutorial walks a user through the entire process of building a 2-Node cluster for making KVM virtual machines highly available. It uses Red Hat Cluster services v3 and DRBD 8.3.12. It is written such that you can use entirely free or fully Red Hat supported environments.

Hi all, I use CentOS5.x + Xen in production for virtualization. I use it with bridged vlan networks and bonding (active-backup) like that: eth0 eth1 | | ------- | bond0-------bond0.10---------bond0.12 ... | | | | vlanbr10 vlanbr12 dom0 | | ------------- -------------- | |

Hi, I am facing a problem when I run tc on the bonded nic cards. When I run tc on a single nic card, it worked perfectly fine. But when I run tc on a bond of two nics, tc gives poor performance. The two nics were bonded in round-robin (load balancing) mode. I created a qdisc, class and a filter as follows: tc qdisc add dev bond0 root handle 1: htb tc class add dev bond0 parent 1: classid

Hi folks, I have run into a confusing problem. My initial problem is: Conga does not offer "Add a virtual machine service". So I googled and found a RedHat advisory on that: http://rhn.redhat.com/errata/RHBA-2009-1623.html which points updates that should fix this. I checked on my cluster, but the relevant packages are current (and even if ALL packages are current it does not work).

I am planning to configure * box A with PSTN interface to route faxes to * box B (running spandsp) over TDMoE. I am using 2xGb bonded NIC's for connection between servers. Was wondering - does anybody have experience with TDMoE over bonded interface - ie. does it work ok?. - does anybody have feedback using this scenario for fax? another question, perhaps someone knows what's the

Which files do I need to edit in order to initialize a route after a reboot. I have a 802.1q tagged VLAN interface which I need to create a rule, and a route for. I see on my CentOs 4.2 box that in /etc/iproute2 there are the following files. I realize that I can add my tables to /etc/iproute2/rt_tables, but when I want to create a rule I am not sure where to put the information for the

I have to provision several dozen * users to a seperate building on our campus in the same subnet. Ordinarily, I'd just run a gigabit cat6 cable to another switch if it doesn't violate the 100 metre rule, but this building is several hundred metres away from my backbone. My only option for cabling to the remote building is copper. My plan is to provision them with a Linux bridge with 4

According to this link, https://rhn.redhat.com/errata/RHBA-2007-0331.html conga, ricci and luci have updates available. I can't find these updates on the mirrors I checked. They are in: http://mirror.centos.org/centos/5/os/x86_64/CentOS/ but not in: http://mirror.centos.org/centos/5/updates/x86_64/RPMS/ Anyone have any ideas about this? TIA Dave

Has anyone successfully created a bonded interface (bond0) with say two nics AND also then aliased that interface to get bond0 and bond0:1 (for an alias ip) I just want to know if it's possible and reliable Thanks -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

Hi, Wondering if this is the proper bridging technique to use for Centos6+KVM; http://wiki.centos.org/HowTos/KVM Before I embark on this again, I would like to do it by the book. Thanks in advance, - aurf

I put this page together just so I won't spam the board anymore begging for help..lol http://bobhoffman.com/vmissue.html This shows a working effort of bonded eths, bridged into a vm, and a few other things. The only missing thing is something on the host that ends up putting the VM internet connection into some kind of limbo. Whether it is hardware related, bug related, libvirt nat

Hello, I have a server with 4 NICS running CentOS 5.2. I have bonded the interfaces together such that 'bond0' consists of eth0-3. This is not a problem, and works fine. However, I now need to create a virtual interface. In a non-bonded server I would just create something like eth0:1, but with a bonded interface I am a bit confused. I have created bond0:1 simple by copying the
