I've encountered an odd error state that I haven't been able to resolve yet. I have a customer that, for what ever reason, wants to use active mode occasionally for FTP xfers. What they have noticed, is that after you switch to active, and issue a command (they do 'ls', I've done other things like 'put' and 'get', etc.), the connection hangs. If you wait a

Hello, I have CentOS 5.2 installed on two of the afore-mentioned blades. I've noticed that the OS started to crash lately (kernel panic) and I've been assigned the task to troubleshoot this issue. I would like to know what is the best way of recovering the kernel dump after the OS crashes. I know there are two software implementations that would enable me to do this, kexec and

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 use the balance-alb mode (mode6), but had little luck (receiving

HI All.

I am working on setting up an NFS server, which will mainly serve files to web servers, and I want to setup two bonds. I have a question regarding *which* bonding mode to use. None of the documentation I have read suggests any mode is "better" than other with the exception of specific use cases (e.g. switch does not support 802.3ad, active-backup). Since my switch *does* support

Hi, in LLVM CVS the afore-mentioned function has 'const TargetRegisterClass*' parameter, that is not documented. Can somebody explain what does it mean? Thanks, Volodya

Hi, may be there are some best practice suggestions for the "best mode" for channel bonding interface? Or in other words, when should/would I use which mode? E.g. I do have some fileservers connected to the users lan and to some ISCSI Storages. Or some Webservers only connected to the LAN. The switches are all new cisco models. I've read sone docs (1), (2) and (3) so the theory

I have a bonded interface running in mode 1 which is active/passive and no issue with this. I need to change it to mode 0 for active/active setup. Does mode 0 is dependent on the switches configuration? My setup is: 2 links from bonded interface is connected to different switches. When I change to mode0 from mode1 , bond0 is not coming up. These are the steps I performed 1) changed to options

Hi, I have been playing this weekend with bonding on PCI netcards and found that all of netcards I have, but old 3com, do not support MII. So bonding is not going to happen with them. Do you have some pci netcards supporting MII successfully running on bonging? Thanks, David Hrb??

Silvertip257, when you did this CentOS 6/KVM/bonding/bridging, did you ever get all the parts playing together correctlhy? I'm facing a setup with only two NIC's, and need for multiple trunked VLAN access, and bonded pairs, and KVM based bridges to get the VM's with exposed IP addresses. I can get basically any 2 out of the 3 server network components working, binding, VLAN's, or

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