I can ping the google.com ip addresses (209.85.231.104) but can't ping the FQDN, obviously DNS is broken.

creating partitions on a 2.7TB drive
by Khusro Jaleel 08 Mar '10

08 Mar '10

Hello, sorry for the long email, it's a little hard to explain this issue. The gist of it is that the Ubuntu version of parted allowed me to do something which perhaps should not be allowed i.e. creating partitions on a 2.7TB drive when the partition table is not *gpt* but *msdos*. I am trying to configure 2 identical servers, both are Dell Poweredge 2970 machines with 6 disks in them configured as a RAID 5 with one hotspare, and both give me 2.726TB of space after the RAID 5 is configured. There are slight differences between the BIOS versions and Firmware versions of the LSI disk controller, etc but I'm not sure that matters in this case. Now, I setup server "A" a few months ago and for some reason that I don't remember now I resorted to using a Ubuntu 64-bit LiveCD to create the partitions. Since the disk is larger than 2TB, I had to use 'parted' to create the partitions. So I happily created the partitions I wanted which are below: / 50 GB /var 20 GB /data the remainder (a large partition) Now, after a few months I forgot all about the Ubuntu LiveCD and tried to setup server "B" using the CentOS 5.3 x86_64 CD. However the installer immediately complained that "this disk in using a GPT partition table and this computer cannot boot using GPT" and it keeps saying this no matter what I do. I've tried creating a separate /boot partition, using LVMs for everything, etc but nothing works, even "dd" did not give me much luck, although perhaps I should try deleting the "end" of the disk rather than the beginning? I have now noticed that when press Ctrl-Alt-F2 on server "B" during the CentOS install and attempt to use 'parted' it says that the "label" type is "gpt". It allows me to create new partitions, etc but it's no help because the installer keeps complaining that the machine will not boot with a GPT partition table. So I need to really use a "msdos" partition type to boot this machine successfully, but the CentOS version of parted will not allow me to do that. The additional mystery is that if I check server "A" which I partitioned a few months ago using Ubuntu, the "label" type is "msdos"!! How is that possible? In addition if I use the CentOS CD and try to use parted on server "A" now, it gives the following error: --------------------------- # parted GNU Parted 1.8.1 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) p Error: msdos labels do not support devices that have more than 4294967295 sectors. --------------------------- BUT if I reboot this same server (server A) again using the Ubuntu LiveCD parted works just fine! It prints the label type as "msdos", and it prints the above partition table correctly and gives me the right size for it and everything. So what is going on here? Is the Ubuntu parted somehow buggy and allowing me to do something dangerous that I will regret later, or can I just ignore the label setting in parted and continue to setup Server "B" the same as "A" and hope for the best? I would appreciate any insights.

openldap-2.3.43 and db4-utils - DB_VERSION_MISMATCH
by Götz Reinicke - IT-Koordinator 08 Mar '10

08 Mar '10

Hi, I just started to set up a test ldap server and followed some tutorials. One topic is the tuning/monitoring of the bdb. So I installed the db4-utils and executed a "db_stat -h /var/lib/ldap/ -m". The answere is no stat, but: db_stat: Program version 4.3 doesn't match environment version db_stat: DB_ENV->open: DB_VERSION_MISMATCH: Database environment version mismatch The systemsetup is a basic, fresh centos 5.4 isntallation. So why do I get this message? db4-4.3.29-10.el5 db4-utils-4.3.29-10.el5 openldap-servers-2.3.43-3.el5 Thanks and best regrads, Götz -- Götz Reinicke IT-Koordinator Tel. +49 7141 969 420 Fax +49 7141 969 55 420 E-Mail goetz.reinicke(a)filmakademie.de Filmakademie Baden-Württemberg GmbH Akademiehof 10 71638 Ludwigsburg www.filmakademie.de Eintragung Amtsgericht Stuttgart HRB 205016 Vorsitzende des Aufsichtsrats: Prof. Dr. Claudia Hübner Staatsrätin für Demographischen Wandel und für Senioren im Staatsministerium Geschäftsführer: Prof. Thomas Schadt

CentOS server running java - won't let go of swap
by Sean Carolan 08 Mar '10

08 Mar '10

I'm monitoring some CentOS 5 servers running Sun Java. We have set things up so 2048 MB of RAM are available for the base operating system, taking into account the xMx and permgen settings. What we're seeing is the swap space getting used up, and not released. Is this normal behavior? Performance doesn't seem to be affected, however I'm a bit concerned that the swap file is completely full: free -m total used free shared buffers cached Mem: 9993 9945 48 0 174 1695 -/+ buffers/cache: 8074 1919 Swap: 2047 2033 14 Here are the xMx and permgen settings: -Xms7177m -Xmx7177m -XX:MaxPermSize=768m Apart from Java/Tomcat/Apache and some HP hardware monitoring tools we are not running anything else on this server.

08 Mar '10

Hi, Will CentOS be present at the "Solutions Linux" fair in Paris ? Other question. I'm currently re-reading "The Definitive Guide to CentOS". The book's introduction mentions 10 million CentOS users worldwide. Wow! I wouldn't have expected that much. How do you get this figure? By the number of downloads? Cheers, Niki

Hey I want to start the next Newsletter early so it can be a little more relaxed. The next release will be the 1. April. I really need someone to *interview*, just drop me a mail and I will send you a few questions. This can be anyone from the community that has some sort of CentOS install. And then I want to introduce a new section called DeskShot where users can show off their workplaces. Something around the lines of [1] [2] Comments, like always welcome :) Cheers Didi [1] http://picasaweb.google.com/ribalba/CernWork#5165470488379454594 [2] http://i790.photobucket.com/albums/yy187/ribalba/CIMG0027.jpg Feel free to obfuscate anything to personal -- Hoffmann Geerd-Dietger http://contact.ribalba.de
