xen and nvidia
by sbeam 13 Aug '08

13 Aug '08

has anyone had any luck getting nvidia to work with the latest xen kernel under x86_64? I found an unsupported method involving IGNORE_XEN_PRESENCE [1], but it doesn't work for me. Everything google turns up seems to be a year old. prob nothing has changed but I just wonder. [1] http://www.nvnews.net/vbulletin/archive/index.php/t-95483.html maybe I could I run a xen dom0 under vmware? nah...

DRBD 8.2 crashes CentOS 5.2 on rsync from remote host
by Chris Miller 13 Aug '08

13 Aug '08

I've got a pair of HA servers I'm trying to get into production. Here are some specs : Xeon X3210 Quad Core (aka Core 2 Quad) 2.13Ghz (four logical processors, no Hyper Threading) 4GB memory Hardware (3ware) Raid 1 mirror, 2 x Seagate 750GB SATA2 650GB DRBD partition run on top of an LVM2 partition. CentOS 5.2 2.6.18-92.1.6.el5.centos.plus DRBD 8.2 (drbd82-8.2.6-1.el5.centos) Kernel Module kmod-drbd82-8.2.6-1.2.6.18_92.1.6.el5.centos.plus I've been trying to rsync data from a remote server and it's crashed a couple of times now. It does not happen immediately, but over time. I connected a serial console and got the below panic message. The last file copied was ~1GB in size, but previous files up to 4GB had been copied. I do not have kernel core dumping enabled, but that's a possibility if needed. Not sure if this is a bug or is caused by something I've done. This isn't my first DRBD install (although first on top of LVM) and I believe I've gotten everything setup correctly. I did have a full sync rate (110M) enabled over Gbe, if that's relevant. Thoughts?

Re: NetBSD on CentOS 5.2 Xen 3

I know nothing about your problem but http://mail-index.netbsd.org/port-xen/2008/01/29/msg003223.html sounds a lot like what you describe. Hint, if you put, "Error: (2, 'Invalid kernel', 'xc_dom_compat_check: guest type xen-3.0-x86_32" in google you might just get the info you need. Do not forget to include the quotes in your google search. Hope this helps. Regards, -- Tom Diehl tdiehl(a)rogueind.com Spamtrap address mtd123(a)rogueind.com

ks
by tony.chamberlain＠lemko.com 13 Aug '08

I made a file partition-ks.cfg and put it in our machine 192.168.5.17 under /var/www/html. When I install a new machine I just do a linux ks=http://192.168.5.17/partition-ks.cfg I have a couple questions though: 1) I have the following in it: clearpart --all part /boot --fstype ext3 --size=100 part /var --fstype ext3 --size=10000 part / --fstype ext3 --size=10000 part swap --size=2048 part /home --fstype ext3 --size=100 --grow which is OK if I am installing over a previous installation. But for new machines it does not seem to recognize the "clearpart" or it is not enough because I am still prompted whether I want to remove partitions. Should I be using something else? 2) I would like to duplicate the CentOS installation disk and place partition-ks.cfg on the disk too so that during boot it automatically is used (or barring that I can still say ks=<dvd drive>/partition-ks.cfg. Automatically would be better. I tried some ways I thought it said to do that but it did not work. Any tips?

gcc editor for newbie (Emacs or vim or ?)
by Lanny Marcus 13 Aug '08

13 Aug '08

I downloaded the .pdf version of "Thinking in C++" and I've begun to read that and I did yum groupinstall 'Development Tools' I'm a Newbie Desktop user, jumping into the deep end of the pool. Should I try to learn vi (Vim) (which obviously will help me, if I ever need to administer a remote box) or install Emacs or something else, for the gcc editor? An easy learning curve is strongly preferred, but, I am 100% aware of the advantages of vi. Recommendations? TIA!

libc.so.6(GLIBC_PRIVATE)(64bit) is needed but I cannot find it in CentOS 5.2
by Erez Zilber 13 Aug '08

13 Aug '08

Hi, I hope it's the right list. Anyway, I'm using CentOS 5.2. I wrote a program that uses rtkaio (so my Makefile contains -lrtkaio). The program runs successfully. The problem began when I wanted to create a rpm for my program. I was able to generate a binary rpm, but when I tried to install it, I got the following error: [root@klab002 tmp]# rpm -i /tmp/mypkg-1.0.x86_64.rpm error: Failed dependencies: libc.so.6(GLIBC_PRIVATE)(64bit) is needed by mypkg-1.0.x86_64.rpm I checked the dependencies: [root@klab002 tmp]# rpm -qRp /tmp/mypkg-1.0.x86_64.rpm /bin/bash /bin/sh /bin/sh /bin/sh /usr/bin/python libc.so.6()(64bit) libc.so.6(GLIBC_2.2.5)(64bit) libc.so.6(GLIBC_2.3)(64bit) libc.so.6(GLIBC_PRIVATE)(64bit) libnickel.so()(64bit) libpthread.so.0()(64bit) libpthread.so.0(GLIBC_2.2.5)(64bit) libpthread.so.0(GLIBC_2.3.2)(64bit) rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rtld(GNU_HASH The problem is that librtkaio uses GLIBC_PRIVATE: [root@klab002 tmp]$ nm /lib/rtkaio/librtkaio-2.5.so | grep PRIVATE U __libc_dlopen_mode@@GLIBC_PRIVATE U __libc_dlsym@@GLIBC_PRIVATE U __libc_fatal@@GLIBC_PRIVATE U __libc_pwrite@@GLIBC_PRIVATE w __pthread_clock_gettime@@GLIBC_PRIVATE w __pthread_clock_settime@@GLIBC_PRIVATE U __pthread_unwind@@GLIBC_PRIVATE U _rtld_global@@GLIBC_PRIVATE But I couldn't find where these symbols are defined (e.g. __libc_pwrite@@GLIBC_PRIVATE). The workaround that I found is to add the following line to the spec file: "provides: libc.so.6(GLIBC_PRIVATE)(64bit)" I guess that there should be a better solution for that. Any idea? Thanks, Erez

conntrack-tools and Session syncing
by Dirk H. Schulz 13 Aug '08

13 Aug '08

Hi folks, I have 2 firewalls, setup with Centos 5.2. They are also routers, connected to 2 upstream routers. I have some cases where connections from servers to the internet leave my network via router2 and answers come back via router1. So I added conntrack tools to both routers/firewalls to synchronize the session tables (using ftfw procotol). That works as expected. If e.g. I ping from an inside server to somewhere outside, ICMP request leaves via router2, the answer comes back via router1. conntrack -e on router1 shows this session (as unreplied), BUT the firewall blocks it as new connection - that means iptables does not recognize conntrackd's addition to the session table. Seems that I have a conceptional misunderstanding here - but I do not find anything that could be wrong. Could somebody please help? I am stuck. Any hint or help is appreciated. Dirk

Kerio Mailserver on Centos 5
by dnk 13 Aug '08

13 Aug '08

I was wondering if any of the mail admins on here have used the kerio mail server on centos, and their thoughts on it. My initial testing is going very well - but was hoping for some unbiased opinions (as opposed to asking on the kerio forum) on it's use with centos (5 in particular if possible). THE typical q's - IE performance, issues, etc. Thanks in advance. Dk

Changing boot drives
by MHR 13 Aug '08

13 Aug '08

This is probably a dumb question, but I haven't found anything that clearly describes what I need. My system has 2 IDE (PATA) hard drives and 2 SATA hard drives. /dev/hda is the boot drive, but /dev/sda contains my CentOS installation, including /boot, /, /home and swap. I know for a fact that there is no MBR on /dev/sda because the system refuses to boot from it. I would like to rearrange the boot order to use /dev/sda as the boot device (mainly because I'm probably going to get either another disk drive or both another disk drive and a m/b soon that does not have two IDE connectors (I have two IDE DVD burners) and I'd rather not replace any more than absolutely necessary to accomplish this. So, what is the best way to put a correct MBR that will boot from /dev/sda on /dev/sda if /dev/sda is the first boot device? Thanks. mhr
