similar to: 4.5 ALB Bonding Hang on Shutdown

Hi, we are trying to switch our bonding modes from 1 (active-backup) to 6 (balance-alb). However it seems, that these bond devices are not always getting the MAC address from the same slave. Sometimes the device gets the MAC address of the first and sometimes of the second slave. Since only the MAC address of the first slave device is (can be) registered in DHCP, this breaks connectivity

I keep reading that RHEL/CentOS 5 supports blktrace, but I can't seem to find the blktrace/blkparse utilities. Is it that just the functionality is available in the kernel, but the user is left to have to hunt down the latest versions of the utilities on the net? If anybody knows where to get the latest versions of these utilities I would greatly appreciate it. Ross S. W. Walker

I have my NIS user/group files separate from the system user/group files using libuser to manage them and that works well, but I am trying to find a way to get libuser to invoke a 'make' of the NIS maps whenever it updates the master files. Is there a routine I can configure in libuser to do this, or am I stuck having to do it by cron? Ross S. W. Walker Information Systems Manager

I have a new development box at home that I am working on. Currently it has CentOS 5.1 + Xen 3.2 running several domUs. I am using XDMCP on the domUs and an X Chooser on dom0 for connecting to them and it works well, but now I want to be able to get sound from my domUs and I have been struggling. I can get some from network transparent sound by using ESD, but I have no way of controlling the

Ok, I got blktrace installed, but I also have some blktrace system taps that I want to test out, but it seems I need to have the kernel debug info installed to get systemtap working. Anyone know where the CentOS kernel-debuginfo RPMs are located? Ross S. W.

I'm creating a firewall HA cluster. The proof of concept for the basic firewall cluster is OK. I can bring up the cluster, start the iptables firewall, and move all of this with no problem. I'm using Conga to do all of this configuration on Centos 6.3 servers. To extend the "HA" part of this, I'd like to use bonded channels instead of plain old NICs. The firewall uses

I have a couple 64-bit CentOS 5 installations here and was wondering if there was a yum option to have it install only x86_64 arch by default if no arch is specified. I tired of having to append .x86_64 on all package names I only want the x86_64 versions of, if I want the i386 versions too I would add the .i386 package to the list... Thanks All, Ross S. W.

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

It would be a handy feature to have idmap_ad implement an alloc routine to write back the uid and gid mappings to AD either as SFU attributes or RFC 2307 attributes. I figure this could allow dynamic uid and gid allocation that can be easily preserved across multiple domains in a Windows environment. Has there been any attempt to provide this feature? Ross S. W.

Dear List Members, Is there a way to prevent a kernel from being upgraded unless a list of given dependencies are satisfied? What I am getting at is sometimes updated kernels are available before the upgraded versions of the kernel modules in 'extras' are (ie drbd). If there were a way to list these modules as dependencies that must be satisfied before a kernel upgrade can be

To all, I was wondering if it was possible to setup samba shares that use subversion as a backing store for the files. Whenever a new file is created it is added to the subversion tree, whenever a file is opened it is checked out of the subversion tree, and whenever it is deleted it is removed from the subversion tree. The idea is that one could use subversion to retain previous versions of

Are there any RPM wizards out there that know how to specify a different architecture for a subpackage in a spec file? I have a package that has a binary component and a non-binary component that I would like split into 2 packages one, the binary which is architecture dependant and the other 'noarch'. I haven't found a spec file that does this yet :-( Ross S. W. Walker

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

I am inquiring on the list if anybody knows if the latest plus kernel includes the fixes for MD RAID-1 where it didn't pass down the BIO_RW_SYNC flag on cloned bios. This bug was discovered in December by the DRBD project and patches were posted by Lars Ellenberg from that project to the LKM which were then merged into the 2.6.19 kernel. The bug causes severe performance penalties for

Currently I'm running CentOS 4.4 on a Dell Poweredge 850 with an Intel Pro/1000 Quad-port adapter. I seem to be able to only achieve 80% utilization on the adapter, while on the same box running Fedora Core 5 I was able to reach 99% utilization. I am using iSCSI Enterprise Target as my application and I am using the nullio feature, it just discards any write and sends back random data for

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
