OEL 6.2 network bonding
Hi all,
I am trying create and test network bonding in OEL6.2 (2.6.32-300.25.1.el6uek.x86_64). OEL6 installed as Oracle VM 3.1.1 Virtual machine.
Problem is that when I created second bond (bond1) I lost my old (bond0) interface IP address.
Now all 4 interfaces linked to bond1 and respectively two of them have wrong IPs.
Please help
./thanks

There are no physical characteristics to the netfront NIC, so I doubt it would work: the bonding drivers use various hardware manipulation techniques to change the MAC address on-the-fly, etc. If you really want to play with bonding inside a guest, you may need to run a fully hardware-virtualized guest and use the emulated Realtek NICs instead.Thanks for explanation. Now everything is clear for me except one thing .... why in my case one bond is still working?

Hello,
I have two connections. One wireless (wlan0) and one wired (eth0).
They are a bit slow, so I thought that I could use both to have a faster internet connection (this is load-balancing, isn't it?).
Is mode balance-tlb right for me?
Also a problem:
$ netcfg bonded

Hi:
I am new to linux and I have a PC( Acer Veriton X275) . I have installed OEL 5.2 on it. but I cannot connect to the internet. I already create a network from my Network Configuration interface. but its Inactive. once I press the Activate button I do have this error :
/sbin/ifup: line 17: ./network-functions: No such file or directory
/sbin/ifup: line 28:need_config: command not found
/sbin/ifup: configuration for eth0 not found.
usage: ifup<device name>
I am using cable connection to the router and it's using the DHCP ( My boss told me the connection is DHCP , I'm not sure about it)..
Do you have any solution for this problem?
Thanks in advanced
sincerely

Edited by: 922700 on Apr 2, 2012 6:59 PMok, also I got this comment from another of my friend. but I want to use the oracle database 11g R2 on linux. As I read the guideline for the database its support the Oracle Linux 5 updat 2. I scared whether I format the OS and the network problem solved but I get another problem with oracle db. do you know oracle db is supported by Oracle linux 6.2 or 5.8 or not?
anyway thanks for your reply -
Why Oracle doesn't have CD image for network installation?
We have old IBM servers where still only CD drive.
And can't to boot from USB sticks.
But same RHEL distros have it!Perhaps you will find the following interesting.

Dear sirs,
in past few days I've been in touch to older x4500. I runs SUSE and we have two RAID5 arrays on it.
My problem is that I'm not able to get more performance that 2 Gbps (gigabits per second). I've looked into documentation and found some notice that is confusing to me and my colleague (as we aren't native speakers).
I read: There are two chips each one supports 1 Gbps on two interfaces (means 2 Gbps in four RJ-45 holes)
My colleague read: There are two cards with four chips each one supports 1 Gbps (means 4 Gbps in four RJ-45 holes)
Before starting hard digging to our kernel and modules I'd like to have confirmed that x4500 supports more than 2 Gbps on intergrated LAN controllers.
Bond is set to 802.3ad (configured well on our CISCO 6500 side) and load is balanced on basis of L4 (IP + port).
Any help is really appreciated.
MIIRC (I haven't checked recently), Mac OS X supports bonding, but uses the standard LACP link aggregation in which all links are simultaneously active (traffic is balanced across all active links).
This usually (but not always) is not possible across multiple switches.
If you want an active/standby port configuration then you may have to roll your own - a simple script that ifconfig up's an interface when the primary fails would be relatively easy to construct. -
Network bond (link aggregate) failing
I have a D-Link DGS-1224T. I have set up a trunk between ports 5 and 6. I have connected cat6 cables between my macpro and those ports. I have gone in and successfully created a bond and given it manual IP settings.
It works great for a little while, then it fails saying that there is no partner. If I recreate, again it works for a short period of time.
Any thoughts?There are a lot of factors, look at N for wireless. Even IEEE has some issues after something is released. FYI: It was originally called IEEE 802.1AX-2008 and before that it was IEEE 802.3-2005 Ethernet. So depending on which format Dlink used they are not incorrect. I suspect you thought it did as did this person:
http://discussions.apple.com/thread.jspa?threadID=361809
Again this is not a manufacture issue. -

alias bond1 bonding
options bonding miimon=100 mode=1 max-bonds=2
(mode=1? means active/passive failover see bonding.txt in kernel sources for more options)
/etc/sysconfig/network-scripts/ifcfg-bond0 looks like:

BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=yes1)what to do get my access to adsl modem?
2)what to do on node2?
i am facing some error when i am installing clusterware bcz the interface names are different in each node.and public and private ip NICs are in different order.
will this bonding solute out this issue?

following the steps from here(but its done on vm-ware):
http://blog.ronnyegner-consulting.de/2009/09/14/oracle-11g-release-2-install-guide-%E2%80%93-grid-infrastructure-installation/Why do you want to use bonding? If this is not a real RAC, what do you want to achieve by bonding?
I do not see a dedicated Interconnect interface. Node 1 has NIC eth1 and node 2 has NIC eth2. One of the basics for RAC is to have the same configuration on each node. So if node 1 uses eth1 for public/virtual/private networking, then so should every other node in the cluster.
If you bond eth0 and eth1, then what do you want to use for your Interconnect? The same bond0 interface that is now used for your RAC's public and virtual interface configuration?
Make sure you understand the basic requirements for a RAC configuration. Make sure you adhere to these - even in a virtualised environment. -
Oracle RAC HAIP vs network interface bonding
Hi,
Oracle intruduced new feature called HAIP (11gR2 Grid Infrastructure Redundant Interconnect and ora.cluster_interconnect.haip [ID 1210883.1] ) in Oracle 11.2.0.2 or later. Oracle GI natively supports HAIP so that user does not need to configure Interconnect network interface bonding anymore.
It seems to me that HAIP will provide better performance than network bonding. Using HAIP, you can have up to four interconnect at work at same time whereas bonding really present as one interconnect IP (ofcause you can have two bondings configured, but still is 1/2 of what HAIP can potentially up to).
Any thought on this?I have implemented this at my site on a two node RAC.
We did test the same by bringing the newly added interfaces down and the failover did happen as expected.
I personally think that OS bonding will be better considering the number of bugs we run into as when the complexity and involvement of Oracle features increases.
Not saying that Oracle is unreliable, but just a personal opinion.
There is already a situation, you may face, wherein after the failover (and failback following the failover) the IPs returned are not correct due to ARP caching if the IPs fall under same network.
This can be avoided by using proven OS bonding (not that I'm aware of any issues with OS bonding :) ). -
OS level load balancing in OEL
Hi,
Would like to know if we can do OS level load balancing with OEL?
I know in Windows there is Network Load Balancing NLB, that would do this, so I am hoping is there something similar in OEL?
Thanks.Optimus prime wrote:

I know in Windows there is Network Load Balancing NLB, that would do this, so I am hoping is there something similar in OEL?Kind of. There are a number of clustering options for Linux. Including commercial products like Oracle Grid.
I think the one of the oldest (and well known) Linux clustering s/w projects is Beowulf.
For networking specifically (comparing it with what I read in Microsoft's FAQ for NLB) is Linux Virtual Server. Quote:
"<i>The Linux Virtual Server as an advanced load balancing solution can be used to build highly scalable and highly available network services, such as scalable web, cache, mail, ftp, media and VoIP services.</i>"
There are also other options - such a network devices (in addition to standard switches and routers) that specifically provides load balancing for networking. Though personally, I did not like this approach much for Oracle RAC and we rolled our own load balancing using NAT and iptables.
Bonding, as mentioned above, is one of many technical considerations when implementing a load balancer. This is (in my experience) primarily for high availability - and provides redundant paths from the server to a resource. Does not need to be IP based - it can be Infiniband based too (e.g. like used by Oracle Database Machine for redundant storage fabric paths to the Exadata Storage Server).
Typically 2 separate interfaces/dual ports will be wired into separate switches that in turn will be wired into the greater network or storage system or whatever. This is then bonded on the server as a single logical interface. If an interface, port, cable or even switch fail, that logical interface still have a secondary path providing full connectivity. Bonding is discussed at http://www.linuxfoundation.org/collaborate/workgroups/networking/bonding.
This is however a very low level of dealing with load balancing (and redundancy). It alone should not be considered as a load balancing solution. -
Network bridging two cable connections. Worth it?
I tend to be a bit (okay excessively) power hungry. My apartment complex provides a free shared wireless cable connection. I found it to be not reliable with uptime and was forced to get a dedicated cable line for myself.
Then I had this thought: when there are times when this wireless and free connection is up and running, would it be worth it to bridge the two connections on my desktop? One would be wired, the other wireless. I haven't yet purchased the wireless card since I'd like some input on this first. Both are cable connections at around 6 mbps (Comcast). I'm fairly savvy with networks however not so much on this concept of bridging in home computing. I use the Internet for large downloads, FTP, SSH, and web design, and I'm just power hungry , so I'm curious what the bandwidth and speed increases would be on this.
My desktop is very powerful and new, if that were to at all be a concern. Any thoughts, experiences, or input on this?

It sounds like you want to combine both physical nics into 1 virtual, this is called bonding.
Download the kernel sources and check Documentation/networking/bonding.txt .
I've done a bit of searching and it seems that downloading large files , ftp and such don't benefit from this as they only can make one connection.
Everyhting that uses multiple connections like p2p should benefit from it.
If you're going to use this, you should consider installing a downloadmanager like prozilla or aria / aria2.
Hmm, me thinks I'll play around with it, thanks! -
Oracle VM 3.1.1 Manager: Configuraing NIC Bonding?
Each of the two OVM 3.1.1 servers in the OVMM 3.1.1 server pool has three Gigabit Ethernet NIC's:
<ol>
<li>One for the Management + VM + Heartbeat Networks (eth0) and
<li>The other two (eth1 + eth2) should be bonded for redundancy and performance and connected to the Live Migration + Storage Networks.
</ol>
However, OVMM 3.1.1 doesn't seem to have the ability to configure the bonding for NIC's. Am I overlooking something?

Truckee, CARefer to the Oracle VM User's Guide for Release 3.1.1:
<li>Chapter 5.4, Network Bonding discusses bonding Management interfaces.
<li>Chapter 5.8, Managing Bonded Interfaces discusses bonding non-Management interfaces.

I need help... i had the network bond setup properly until the last update of netcfg: Since then, i cannot start the bonded interface: It gives an error saying that eth0 and eth1 are down and cannot make the bonding... I tried to fix it myself but failed to.... someone can give me a hand? The wiki is outdated because the configuration from /etc/rc.conf on this matter should be commented and configured somewhere else....
EDIT: Sorry, i kind of panicked... i will collect all the info i can to ellaborate a bit more the case and post an answer.... BWT.... i had to FORCE the update of netcfg because while installing it was complaining that /etc/network.d/examples/bonding already existed....
As said... i will post back with more info.... but basically, when i try to bring the bonding profile up, bonding eth0 and eth1, /etc/rc.d/network-profiles complains that those interfaces are down.....
Last edited by Xi0N (2012-05-31 15:21:40)Ok, the setup is as follows:
De-activated network daemon and using net-profiles daemon in /etc/rc.conf
Added the bonding module in /etc/rc.conf
Then, I created a profile under /etc/network.d/bonded
CONNECTION="bonding"
INTERFACE="bond0"
SLAVES="eth0 eth1"
IP="static"
ADDR="192.168.1.245"
GATEWAY="192.168.1.155"
DNS=("192.168.1.2")
/etc/conf.d/netcfg has only one line enabled:
NETWORKS=(bonded)
The other ones are commented out
If I run /etc/rc.d/net-profiles start, i get the message:
bonded up
> Slave eth0 is down and timeout reached
> Slave eth1 is down and timeout reached
> No slaves up, aborting
> No profile Started
That profile used to work until the upgrade.......... if any more info is needed, ask me and i will post it ASAP...

I created a bonding interface as described in metalink article: Enabling Network Bonding in Oracle VM for x86 [ID 738269.1]
Question:
brctl show is showing that eth0 was replaced by bond0 --> thats fine.
But I created my brigde interface with interfaces eth0 and eth4
But brctl show is still showing interface for xen bridge xenbr4 is eth4.
Shouldnt that be modified to xenbr0 as well ?Chris,
The metalink OVM networking notes are a little rough and incomplete, please check your configuration against http://itnewscast.com/chapter-7-oracle-vm-networking-8021q
I'm sure the link will assist.

Recommendations for XenServer network configuration on B200M2
We are just starting a XenApp / XenDesktop / VDI project at our company. I'm very familiar with VMware as that is the hypervisor we primarily use on UCS. I'll be using XenServer for this project though as the licensing comes with the Citrix licensing. Does anybody have a recommended configuration for the nics in a XenServer running on UCS B200M2's. The adapters in the B200M2's are the M81KR's so I was going to setup them up similar to how I setup and ESXi server.
That would be the following:
Management network (this would use the same native vlan that I use for the management network of my ESXi hosts)
1 nic on fabric A that doesn't failover for the management network (bonded with nic listed below)
1 nic on fabric B that doesn't failover for the management network (bonded with nic listed above)
XenMotion (this would use the same native vlan that I use for VMotion in VMware)
1 nic on fabric B that can failover to fabric A
Guest / VM Network (this I would use vlan tagging to add the appropriate networks for my desktops)
1 nic on fabric A that doesn't failover for guest / vm network connectivity (bonded with nic listed below)
1 nic on fabric B that doesn't failover for guest / vm network connectivity (bonded with nic listed above)
Could somebody offere some suggestions / recommendations on how they have setup there XenServers in UCS for VDI / XenDesktop?Hey Russ, I have deployed XenServer on UCS a lot and here is our standard config that has worked for my customers.
2 vNICs for management, 1 on Fabric A and 1 on Fabric B
2 vNICs for VM traffic, 1 on Fabric A and 1 on Fabric B
If using IP storage then 2 additional vNIC for that, 1 on Fabric A and 1 on Fabric B
2 vHBAs for FC SAN, 1 on Fabric A and 1 on Fabric B
Make sure you have a BIOS policy that disables all of the Intel C-States -
I have a layer 2 problem (network looping) in my network some days ago and this problem was solved when I removed all exadata data connection from my external network switches. Somebody have similar problem here ?
This sounds like a misconfigured active-active bonding configuration. With an active-active bond, both the switch and the database server must have link aggregation properly configured on the right ports, unlike active-passive bonding where no switch configuration is required.
You can test this by disabling bonding in your network configuration, and seeing if your network loop goes away.
There's some brief network channel bonding documentation in chapter 2 of the Exadata Owner's Guide. The official (if somewhat technical) documentation would be in the Linux kernel's bonding.txt though: https://www.kernel.org/doc/Documentation/networking/bonding.txt
