similar to: Kernel debug info?

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 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.

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

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

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

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?

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

I have a 5.1 system with Xen installed. The package says 3.0.3, but an 'xm info' shows 3.1. So what is it? Is it 3.0.3 patched to 3.1 or is it 3.1 packaged as 3.0.3? And if it's the former, does anybody have any idea why upstream wouldn't just deploy 3.1 (now 3.1.2) which is more stable? -Ross ______________________________________________________________________ This e-mail,

I wouldn't necessarily wipe the whole HD, just the windows partition. You could also use Xen in CentOS 5 for your Windows virtualization. I'd wait for 5.1 though which will be more refined then version 5. I've been thinking of setting up a Xen machine of my own with a Windows HVM and a couple of Linux PVMs with their GUIs/consoles pinned to different virtual consoles. It has always
