Many thanks and a little hint concerning httpd on 5.6
by Olaf Mueller 08 Apr '11

08 Apr '11

Hello CentOS developer team, thank you very much for the release of CentOS 5.6. I have upgraded my server, notebook, netbook and workstation from 5.5 to 5.6 and everything works really fine so far, CentOS 5.6 seems to be rock solid. The only little problem happens on the upgrade of my server, since my web server doesn't start after reboot. But this was easy to fix since this error was known from the RHEL 5.6 upgrade. https://bugzilla.redhat.com/show_bug.cgi?id=669963 I am grateful for the CentOS Project. I like it's stability and long-term support. regards Olaf

large memory usage by perl .so modules?
by E R 08 Apr '11

08 Apr '11

Under Centos 5.5 on an x86_64 box I am seeing large memory usage associated with perl .so modules. Example: this script: #!/usr/bin/perl use Time::HiRes; open(SMAPS, "/proc/$$/smaps"); while (<SMAPS>) { if (m/^\d/) { chomp($lib = (split(' ', $_))[5]); } elsif (m/^Size:\s*(\d+.*)/) { my $size = $1; print "$size $lib\n" if ($lib =~ m/HiRes/); } } produces this output: 24 kB /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/Time/HiRes/HiRes.so 2044 kB /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/Time/HiRes/HiRes.so 4 kB /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/Time/HiRes/HiRes.so What is this 2044 kB entry? On a 32-bit Centos 5.4 box the same script emits: 20 kB /usr/lib/perl5/5.8.8/i386-linux-thread-multi/auto/Time/HiRes/HiRes.so 4 kB /usr/lib/perl5/5.8.8/i386-linux-thread-multi/auto/Time/HiRes/HiRes.so The 2044 kB entry seems to be counted towards memory usage as reported by ps. Thanks!

I wonder if you you have better luck installing GRUB on the HDD MBR, booting from the HDD and using grub to load the kernel and initrd off the USB stick. What you have to do is tell it no bootloader, then before you reboot at the end of the install, use <f-2> or whatever to get to another screen, then... lessee, I forget if it's mounted the install as /mnt/sysimage or not, but mount your /boot on the h/d, chroot, edit /boot/grub/device map so it shows HD 0,0, and then grub-install /dev/sdb (or whatever). Then when you reboot, you should be ok; if not, linux rescue, and do all that. mark, who wishes upstream would *offer* the option of other than /dev/sda or track 1 of this drive....

/etc/hosts not resolving hostnames
by Johan Martinez 08 Apr '11

08 Apr '11

I have modified /etc/hosts file with IP address and hostname entries. However, host command is returning 'Host vhost1.example.com not found: 3(NXDOMAIN)'. Also, apache is returning error on start as '[error] (EAI 2)Name or service not known: Could not resolve host name vhost1.example.com-- ignoring!' . The ssh worked fine and resolved the hostname correctly (ssh from same system to itself - just for test). Am I missing something here? I thought /etc/hosts will be referred for all lookups. Any help?? jM.

Exception error with 5.5 installation
by Kaplan, Andrew H. 08 Apr '11

08 Apr '11

Hi there -- I am trying to install the 64-bit version onto one of our servers. When I get to the point of loading various software packages, I normally select KDE desktop, and also make sure that CentOS extras is also selected. Once that is done, I click on Next to have the installation continue. Every attempt that I have made has resulted in an exception error occurring with the python packages. As a result, the installation fails. I have not been able to install CentOS since this problem started occurring. Does anyone know of a way I can get around this problem? Thanks.

iptables package issue
by Joseph L. Casale 08 Apr '11

08 Apr '11

I just did a test install off a netinstall iso to a mirror repo which left no /etc/sysconfig/iptables file in place. So a quick check: # yum whatprovides /etc/sysconfig/iptables --disablerepo=\* --enablerepo=base --enablerepo=updates --disableplugin=\* No Matches found Without that file iptables doesn't start as per the init script. Anyone know what may be awry? Thanks, jlc

STOP THIS THREAD NOW!
by Kai Schaetzl 08 Apr '11

08 Apr '11

Folks, it has been asked a few times: PLEASE STOP THE "6 UPDATE" THREAD now! Developers: please just stop responding to that thread. It's not necessary to defend yourselves over a certain point (that has long been reached). Non-devs: if you think you can make a valuable contribution to centos infrastructure/development, please move over to centos-devel and make your serious offer *kindly* there. Any one else: JUST STOP, thanks! I'm really tired of this. Ralph: please unsubscribe everyone who can't shut his mouth. Thanks. A lot of of less-vocal people will thank you. Kai

Can anyone suggest a SCSI 3 card in either PCI-X or PCI-E x 4 for a Dell Poweredge 2900?
by Kevin Thorpe 08 Apr '11

08 Apr '11

The only PCI-X card I have is an old ICP Vortex RAID controller and the Dell hangs with that installed (BIOS is disabled). It's only for a tape drive so performance isn't really an issue. thanks

Controlling the order of /dev/sdX devices?
by Cal Sawyer 08 Apr '11

08 Apr '11

Hi CentOS 5.4(final) 2.6.18-164el5PAE. I am trying to prevent removable USB and eSATA devices from occupying /dev/sdX devices ahead of a 3ware RAID controller. For example: at boot, if a USB drive and eSATA HDD (connected to an LSI 1068E onboard controller, reflashed in "IT" mode to handle hotplug devices) were both present, they would occupy devices /dev/sdb and /dev/sdc, ahead of the RAID controller which ends up as /dev/sdd. As these are removable devices, they should normally get handled by custom udev script looking for adds matching KERNEL=="sd[c-z][0-9]" ,SUBSYSTEM=="block", so the volume handled by RAID controller gets grabbed by udev but fails to mount and subsequent udev plug events fails due the slots left empty below /dev/sdd. If no hotplug devices are present while booting, fstab handles mounting of the system and RAID volume: SATA system HDD /dev/VolGroup00/LogVol00 / RAID array LABEL=STORE /store ## mounts == /dev/sdb1 I realise this description is kind of a tangle, but i am essentially looking for a way to hard-map the 3ware RAID controller to /dev/sdb (UUID won't work as there are multiples of this system) before PCI (?) enumeration picks up the USB and LSI-managed devices so that udev can take care of the device at /dev/sdc and above. I've tried blacklisting the mpt and usb-storage modules and short-circuiting SUBSYSTEM=="block" devices in 05-udev-early.rules, all with zero or negative effect. rc.sysinit doesn't appear to be the right place and that's about as deep down as i know how to go. cheers, cs
