Hi All, I see an unexpected beahviour from NetworkManager on CentOS 7.1. Using nmcli tool, I create a bond with two slaves as explained in the Red Hat 7.1 Networking guide. I enable slaves and master; bond works as expected. When I restart NetworkManager, it creates a new bond with the same name but not connected to any device. Two bonds with the same name is confusing for my other monitoring

There's still room for additional refactoring as we may want to eventually split out nic, bonding, and ip address manipulation into their own controller/svc module, but that would be a much more extensive redesign than we want to deal with for the overall service layer creation refactoring.

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 tr...

Hey everyone, I am developing a package and I am wondering if there is a good practice for naming classes, builders, attributes getters and setters when dealing with object composition. I know that it is usually a good practice to give to the builder the same name as the class and, if possible, to avoid to use upper case letters. My problem is that, when I build an object containing an other

I''m using bonding in active-fallback mode to guarantee maximum availability on some critical servers. The mii mode is active so I can detect things like dead card and/or unplugged cable even on the inactive slave. But how do I check that the inactive slave is properly configured/connected to the switch/vlan? I as...

Getting "bnx2i: iSCSI not supported, dev=eth0" for all the NIC adapters on all of my R710's running CentOS 5.5. Here is an sample of the error messages: bonding: Warning: either miimon or arp_interval and arp_ip_target module parameters must be specified, otherwise bonding will not detect link failures! see bonding.txt for details. bonding: bond0: setting mode to active-backup (1). bonding: bond0: Setting MII monitoring interval to 500.

With the current talk on bonding, I have a few questions of my own. I'm setting up a KVM host with CentOS 6.3 x86_64 on which I'd like to attach the VMs to a bonded interface. My target setup is one where two GigE NICs are bonded and then the KVM bridge interface is attached to the bonded interface. Initially I tried to...

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...

Hi all, i have a xen 4.3 installation and would like to have a bridge bond szenario: *** eth0 eth1 | | bond0 | br0 | vif = [ ''bridge=br0,mac=xx:xx:xx:xx:xx:xx'' ] *** With the network script in debian wheezy *** /etc/network/interfaces auto bond0 iface bond0 inet manual slaves eth0 eth1

I four nodes setup to do active-backup bonding and the drivers loaded for the bonded network interfaces vary between tg3 and e100. All interfaces with the e100 driver loaded report errors much like what you see here: bonding: bond0: link status definitely down for interface eth2, disabling it e100: eth2: e100_watchdog: link up, 100Mbps, full-...

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

As the issue concerns both the -user (configuration) and -devel (OOPS), I''m sending this message to both lists. Some time ago I complained about two problems: - VLANs are not working on machines with 100 Mbit cards - I get a kernel Oops (sometimes panic) when I try to use bonding and VLANs with Xen The root of the issue is the same in both cases: VLAN interfaces must *not* be brought up before we start our Xen network scripts. So have four cases with Xen: 1. Bonding + VLAN leads to an Oops 2. Bonding + VLAN works 3. VLANs don''t work with 100 Mbit cards 4. V...

Hi all, Someone played with kickstart bonding with centos 6.4 ? CentOS 6.4, as upstream now support ifcae bonding in kickstart network section. I've an issue with configuring a second bonding iface in kicstart on CentOS 6.4. The first bonding (bond0) works as espected but the second is not configured during installation. I've a 6 nic...

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....

...e 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.
