Is there some nice program that will display how much disk space is being used by each directory? e.g. 3.9G / 1.6G /etc 3.4K /etc/yum.repo and so forth?

Bind DNS service
by Nikos Zaharioudakis 04 Aug '06

04 Aug '06

Hi everybody, I have a request from a client that is an planning on a small ISP business. I am looking into a DNS {bind based} solution. Are there any hints or tips concerning hardware requirements? Is there any kind of tool to perform the sizing? Should I have different machines for caching ? Should i compile bind myself for xtra performance. There are going to be some 400K dsl customers and some 50-70K virtual hostings I know that most dns trafic is generated by MX lookups. Any hints are greatly appreciated. -- ########################################3 Zaharioudakis Nikos mob: +30 6947204063 A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?

It should be relatively simple but test on non-critical, non-production systems first, obviously. The old instructions (we Kickstart CentOS on all new systems now) I have for switching from Whitebox to CentOS, which should be near as damnit what's needed to switch from RHEL too, were as follows... rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-4 rpm -Uvh http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… \ http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… rpm -Uvh http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… rpm -e yum rpm -Uvh http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… rpm -Uvh http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… \ http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… \ http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… \ http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… \ http://www.sunsite.org.uk/sites/msync.centos.org/CentOS/4/os/i386/CentOS/RP… Add this to /etc/yum.repos.d/CentOS-Base.repo [base] name=CentOS-$releasever - Base baseurl=ftp://archive/centos/$releasever/os/$basearch gpgcheck=1 [update] name=CentOS-$releasever - Updates baseurl=ftp://archive/centos/$releasever/updates/$basearch/ gpgcheck=1 [extras] name=CentOS-$releasever - Extras baseurl=http://archive/centos/$releasever/extras/$basearch/ gpgcheck=1 enabled=0 Add this to /etc/yum.repos.d/Dag.repo [archive-rhel4-dag] name=RHEL4 Linux $releasever - $basearch - DAG baseurl=ftp://archive/dag/el4/ Quick Yum update... yum -y update Where we have "archive" you'd need to replace that with the path to a local mirror.

There are additional artwork RPMs etc. if you're bothered about boot time splash screens and the like.

OT: Measure 2U Server Amp Usage
by Karl R. Balsmeier 04 Aug '06

04 Aug '06

Hi, Running a bunch of CentOS servers on 2U supermicro equipment, usually with 8 drives on Adaptec SmartRAID V or LSI Megaraid. In designing a rack in a data center, the question arises as to how to measure the amperage the server uses, prior to investing in power drops that actually do that for you, even remotely, for about $260.00-300USD per unit. This number is the important one these days in determining rack/datacenter design. So the geek question is, "what do you use, from radio shack, or elsewhere, to accomplish this one time measurement *before* you implement a design"? Even deeper, is there an open-source equivalent to some of the software-based solutions that purport to be able to give a reading on amp usage. Just curious if you have a similar server-type, (supermicro=very popular), what your measurements have been. -karlski

EXT3-fs error (devive dm-0) in start_transaction: Journal has aborted
by Alfred von Campe 03 Aug '06

03 Aug '06

My recently installed CentOS 4.3 system (which is the kickstart server for other systems -- see other thread) is currently hung. I can ping it, but can't do much of anything else. When I switch to one of the virtual consoles, I can briefly see the "login:" prompt, but then that window immediately fills with up with the following message: EXT3-fs error (devive dm-0) in start_transaaction: Journal has aborted This is displayed over and over again. I used the default (automatic) partitioning scheme, so the root file system is an ext3 partition on a logical volume that spans most of the disk (everything except for the swap partition and /boot). Anyone else seen this? Any ideas as to what would cause this? I'll be rebooting the system shortly... Alfred

Hi, Alfred von Campe wrote on Wed, 2 Aug 2006 09:34:06 -0400 > It's time to resurrect this thread from way back in June. I suspect this is more of a HW problem rathan a SW one. About two years ago I had a similar EXT3 fs failure case to develop on a server running Mandrake Linux. My case was due to the fact that this desktop Linux computer had two HDs, where one of them (a Quamtum, top unit on the stack) got overheated because of the heat emitted by the bottom unit (a Maxtor). I tried using a recue CD disk to fix the data errors and limped along for approximately three months. But I but did not manage to pin down the problem till the top HD eventually died and noticed that it was burning hot! So, open the box while it is still running now and feel around to find if something is wrong. - Nobu Toge
