Compiling Kernel Modules
by Maciej Zenczykowski 04 May '05

04 May '05

Hi, Here'a a question - is it possible to compile a single module (distributed in the kernel source tree) for the current CentOS kernel (2.6.9-5.0.5) without recompiling the entire kernel and all other modules. I basically need reiserfs3 (nb. why is it disabled? it's a module, you use it, it doesn't wreck anything...) and I don't really want to change the rest of the kernel, and I'd like to have the minimum amount of fuss on future kernel upgrades. Now I know external modules can be compiled without recompiling the kernel - question is how to do it for an internal kernel module. What I've tried: I've installed the kernel source code, copied over the kernel settings (the entire /usr/src/kernels/2.6.... dir) onto it. run make menuconfig and selected modular reiserfs. A diff of the new and old configs shows only reiser module (and suboptions for selinux) has been enabled. So no other changes have been made. Now a make fs/reiserfs/ almost works, but it borks on some sort of .tmp_versions/reiserfs.mod problem (file not present). The resultant reiserfs.o doesn't work as reiserfs.ko (not sure if it should, though).. I can't run make modules_install without first compiling all the other modules... Should I just grep through the .config file and replace all (except reiser) =m with =n's (and rerun make oldconfig to make sure it's still consistent)? And then run make modules modules_install? Any ideas? Basically all I want is reiserfs3 for the current CentOS4 kernel... Cheers, MaZe.

User Mode Linux and the CentOS 4.0 Kernel
by Bill Bydder 04 May '05

04 May '05

Does anybody know where I might find a stock standard ready rolled binary CentOS Kernel (2.6.9-5.0.5.EL) rpm package BUT with the skas mode uml (user mode linux) patch applied ? If not I will try and build one myself......gulp.... ;-) Is there any good howto's out their on how to do this? It all appears very different with CentOS 4.0 and the 2.6.9-5.0.5.EL.src.rpm. Cheers Bill

I had some incorrect usage on genhdlist/pkgorder that was causing the problems. Referencing these and tweaking a couple things has resolved the problem. Thanks much! Dave

CentOS 4 - problem with remote X application
by Petr Klíma 03 May '05

03 May '05

Hello i have a problem on CentOS 4 with starting remote x application on remote CentOS 3 od Solaris 9 boxes. The problem is: When I run it from CentOS 3 it's OK form CentOS 4 I cannot find a bad word in logs ... My local machine stoping firewall [root@klima-pc ~]# service iptables stop [root@klima-pc ~]# iptables-save [root@klima-pc ~]# SELinux is OFF I am connecting by ssh with Xforwarding enabled to - Centos 3 box [09:32 root@tux:root]# gvim --sync The program 'gvim' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAtom (invalid Atom parameter)'. (Details: serial 287 error_code 5 request_code 20 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) [09:33 root@tux:root]# -Solaris 9 box root@sun bin# gvim --sync Gdk-ERROR **: BadAtom (invalid Atom parameter) serial 364 error_code 5 request_code 20 minor_code 0 Gdk-ERROR **: BadAccess (attempt to access private resource denied) serial 365 error_code 10 request_code 102 minor_code 0 root@sun bin#

RE: Vacation forwarder - syntax of .forward file - FIXED
by Nigel Kendrick 03 May '05

03 May '05

Sorted!! Looks like I started to play around with my user account while still logged in as root, and .vacation.db in my home directory was owned by root:root - changing it to nkendrick:root has fixed the problem. Regards, Nigel

Vacation program
by Nigel Kendrick 03 May '05

03 May '05

Is anyone else running the 'vacation' mail forwarder on Centos 3? When I 'make install' I get the following error: strip: /usr/bin/vaclook: File format not recognized When I try and use vacation (with postfix), it 'goes through the motions' but inbound mail bounces with <nkendrick(a)munged.home.local>: Command died with status 1: "/usr/bin/vacation -a nkendrick(a)munged.com nkendrick" I have sent a mail to the postfix list too but I thought I'd see if anyone here has any ideas too. Thanks Nigel

No. Since /dev/md0 is loading OK in fstab, I have not messed with it further. My guess is, if you did, the kernel would > bring it up as > soon as raid* device drivers are loaded.

[ANNOUNCE] Areca SATA RAID drivers for CentOS 4.0
by Matt Dainty 02 May '05

02 May '05

Hi, To follow up my CentOS 4.0/Areca SATA RAID driver disk I created a month or two ago, I have now created kernel-module-arcmsr RPMs containing just the kernel module to track the kernel updates. This means: a) No need to patch, rebuild and maintain customised kernels for Areca support b) Keep everything maintained with RPM I've taken the latest 1.20.00.07 kernel driver source as found in the 2.6.12-rc1-mm3 kernel, and built it for all variations of the i586/i686/x86_64 2.6.9-5.0.5.EL CentOS 4.0 kernels. I've also updated the driver disk so it now has the same kernel driver, but built for all of the i586/i686/x86_64 2.6.9-5.0.3.EL kernels used on the installer. There is also a nosrc RPM for the various utilities Areca offer, but you'll have to build that one yourself as I don't know what license they're released under. As before, you can get them from here: http://www.bodgit-n-scarper.com/code.html#centos I only have an x86_64 machine with an Areca card, so if anyone is using these packages on an i586 or i686 machine, please drop me a note so I at least know they work. Thanks Matt

I did not mark the parition type to FD so apparently the kernel or mdadm just executes and looks in the ndadm.conf file. When trying to start the raid manually, I found that the raid would fail unless I passed the partion assignments on the commandline to mdadm. However, when the DEVICE and ARRAY are defined in the mdadm.conf, the partion info was not required, just the device name, "/dev/md0". So, I think the raid failed to start at boot due to not enough information being available for it to startup, thus the mdadm.conf file being required. Anyway, that's what my experince told me! > -- > Les Mikesell > les(a)futuresource.com > > > _______________________________________________ > CentOS mailing list > CentOS(a)centos.org > http://lists.centos.org/mailman/listinfo/centos > -- Lee Parmeter Emperor, linXos - The Flying Penguin http://www.linXos.com Linux Registered User #337161 'It's free.
