ARGH!!! Instal fails at drive format time
by Robert Moskowitz 07 Jan '08

07 Jan '08

Got all the way through the selection of packages. All those time consuming tasks and the install got to formating the drive and crashed on a format error! Since I know exactly how I want to lay out the partitions, is there a way I can boot from CD, and get into Disk Druid to set the partitions and do the formating. Then when I come to the install just select to keep the drive how it is? And I have to have LVM....

Migrating software raid from SUSE 9.0 to Centos 5
by Dan Carl 07 Jan '08

07 Jan '08

I have a SUSE 9.0 box with a software raid. It consists of 6 IDE drives and three different controllers The OS is on a separate drive. What I want to do is put a new boot drive in load Centos on it. Then I want to be able to mount the raid without loosing any of the data on it. What information do I need from the SUSE OS (raid info etc...) to tell Centos how to recognize it? The data is backup on DVD's but it would be a real pain to reload it.(its around a terabyte of data) So I'm writing here for some advice. I've setup many raids in the past but only fresh installs. Thanks

DRBD NFS load issues
by Jed Reynolds 07 Jan '08

07 Jan '08

My NFS setup is a heartbeat setup on two servers running Active/Passive DRBD. The NFS servers themselves are 1x 2 core Opterons with 8G ram and 5TB space with 16 drives and a 3ware controller. They're connected to a HP procurve switch with bonded ethernet. The sync-rates between the two DRBD nodes seem to safely reach 200Mbps or better. The processors on the active NFS servers run with a load of 0.2, so it seems mighty healthy. Until I do a serious backup. I have a few load balanced web nodes and two database nodes as NFS clients. When I start backing up my database to a mounted NFS partition, a plain rsync drives the NFS box through the roof and forces a failover. I can do my backup using --bwlimit=1500, but then I'm not anywhere close to a fast backup, just 1.5MBps. My backups are probably 40G. (The database has fast disks and between database copies I see run at up to 60MBps - close to 500Mbps). I obviously do not have a networking issue. The processor loads up like this: bwlimit 1500 load 2.3 bwlimit 2500 load 3.5 bwlimit 4500 load 5.5+ The DRBD secondary seems to run at about 1/2 the load of the primary. What I'm wondering is--why is this thing *so* load sensitive? Is it DRBD? Is it NFS? I'm guessing that since I only have two cores in the NFS boxes that a prolonged transfer makes NFS dominates 1 core and DRBD dominate the next, and so I'm saturating my processor. Thots? Jed

Wondering about CentOS 5.1 functionality

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I'm giving serious thought to loading 5.1 on my Inspiron 1501 laptop, but I'm wondering about certain hardware support such as the following: - - Broadcom Wireless Adapter - 1390 Wlan (bcm43xx) - - USB (Pny Memory Stick - everytime on previous version CentOS has eaten the damned things) - - pptp vpn client(s) Any comments? thanks, Mark -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4-svn0 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFHfwl4AHUWFbtwPigRAvYRAJ9rPLV4QndZfauCtT2NaRVNgxxO+gCfVOD6 gzum1eGG/6Bxa22CIU2zDl8= =zTJx -----END PGP SIGNATURE-----

/etc/passwd aand /etc/shadow out of sync on 4.6 box
by Joe Klemmer 07 Jan '08

07 Jan '08

Fellow list members, I recently tried to add a user to a little used server that hadn't see a change in users for quite a while. When I use system-config-users I get an error alert that says - The user database cannot be read. This problem is most likely caused by a mismatch in /etc/passwd and /etc/shadow. The program will exit now. I awk'ed out the user ID's and ran diff. That came back with the shadow file having two more users than the passwd file. Ok, fine, whatever. But the trick now is how to fix this. Can I just use vi and delete the offending lines from the shadow file? Is there a utility or script that will sync them in a less potentially destructive way? Any pointers to info on this are greatly appreciated. Thanks, Joe -- Boring Home Page - http://www.webtrek.com/joe See my blog, sumo game ranks and other interesting junk

PXE problem after CentOS reboot
by Andrey Slepuhin 07 Jan '08

07 Jan '08

Dear folks, We are installing a large diskless cluster using CentOS 5.1. The hardware is pretty new - Supermicro X7DWT boards with Harpertown CPUs. Unfortunately we have some PXE-related problems described by the following scenario: 1) Set up DHCP, TFTP and NFS on a server, prepare PXE kernel and initrd - fine. 2) Start up the node using PXE for the first time - fine. 3) Reboot the node - PXE boot fails for all next attempts. We see that a server gets DHCP requests and answers them, but a node doesn't response with DHCP ack. The typical DHCP log is: Jan 5 09:14:34 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:34 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:36 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:36 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:40 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:40 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:48 shoffner dhcpd: DHCPDISCOVER from 00:30:48:7e:24:a6 via eth1 Jan 5 09:14:48 shoffner dhcpd: DHCPOFFER on 10.1.5.2 to 00:30:48:7e:24:a6 via eth1 4) Anything like DHCP server restart, node reset, node power on/off doesn't help 5) The only thing that will enable system to boot again over PXE is to perform "bmc reset cold" command on a node using ipmitool - yes, we have IPMI card sharing the same Ethernet interface. After that we can boot CentOS again. 6) When Linux is loaded, if we reboot a node using "bmc power cycle" instead of reboot or shutdown, a node will boot for the next time without problems 7) There are no problems with a second GbE interface (without IPMI) 8) So our guess is that Linux on a reboot leaves Ethernet device in some state that cause brain damage for IPMI+PXE combination. We tried to play with some e1000 driver options, we are also tried latest Intel driver - nothing helps. Do you have any idea what goes wrong? Any help will be much appreciated.

tomcat still sees jvm version 1.4.2 in Cent OS 5
by Isaac Gonzalez 07 Jan '08

07 Jan '08

i chose to install tomcat during the OS install as well as java....however, since I needed to use a different jvm, i used the method described in http://wiki.centos.org/HowTos/JavaOnCentOS for Sun jdk 1.5.0_13 and it worked fine as I can tell, as using the alternatives --config java command, i see both 1.4.2 and 1.5.0 versions and choosing the 1.5.0 version yields the right version when doing a "java -version" command....also doing a "which java" also points to the right location for the java 1.5.0 install...everything appears fine except that tomcat still sees java 1.4.2 as its jvm version... I have tried setting the path to JAVA_HOME in the tomcat5.conf as well as set the JAVA_HOME & JRE_HOME environment variable as a script under /etc/profiles.d....its as if tomcat is ignoring this and still using java 1.4.2! # /etc/init.d/tomcat5 version Server version: Apache Tomcat/5.5.20 Server built: Sep 27 2007 12:16:07 Server number: 5.5.20.0 OS Name: Linux OS Version: 2.6.18-8.1.15.el5 Architecture: i386 JVM Version: 1.4.2 JVM Vendor: Free Software Foundation, Inc. # java -version java version "1.5.0_13" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05) Java HotSpot(TM) Client VM (build 1.5.0_13-b05, mixed mode) # alternatives --config java There are 2 programs which provide 'java'.
