boot problem after disk change on raid1
by Bünyamin İzzet 08 Sep '11

08 Sep '11

Hello, I have two disks sda and sdb. One of the was broken so I have changed the broken disk with a working one. I started the server in rescue mode, and created the partional table, and added all the partitions to the software raid. *I have added the partitions to the RAID, and reboot.* # mdadm /dev/md0 --add /dev/sdb1 # mdadm /dev/md1 --add /dev/sdb2 # mdadm /dev/md2 --add /dev/sdb3 # mdadm /dev/md3 --add /dev/sdb4 *After reboot, server did not boot. So I do the followings:* # mount /dev/md1 /mnt/rescue # mount /dev/md0 /mnt/rescue/boot # mount -o bind /dev /mnt/rescue/dev # mount -o bind /proc /mnt/rescue/proc # mount -o bind /dev/shm /mnt/rescue/dev/shm # mount -o bind /sys /mnt/rescue/sys # chroot /mnt/rescue *I checked the device.map* # cat /boot/grub/device.map (hd0) /dev/sda (hd1) /dev/sdb *And, install the grub.* # grub Probing devices to guess BIOS drives.

Help with kickstart install
by Jerry Geis 07 Sep '11

07 Sep '11

I am doing a kickstart install for CentOS 6.0 (x86_64 install) The error on screen is "fatal error occurred when install glibc package. Could indicate error with install media" When I looked at the /mnt/sysimage/root/install.log file I see Installing glibc-2.12.-1.7.el6.i686 error unpacking of archive failed on file /lib/ld-2.12.so;4e66d2ec cpio read failed bad file descriptor. (Note I am installing x86-64 but the error is on i686 file) This happens (same error) on 2 machines. AMD box with two 2T hard disks in each box for software RAID. I am using a PXE boot environment. Same environment I use for 5.6 (works fine). My kickstart file has the "repo" line commented out, so my local repo is not interfering. These CentOS 6 files were copied direct from DVD back on Jul 3. How do I find out what is wrong with the file and correct it? These are my files: ls -l /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-* -rw-r--r-- 1 silentm silentm 4466416 Jul 3 00:10 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-2.12-1.7.el6.i686.rpm -rw-r--r-- 1 silentm silentm 3920028 Jul 3 00:17 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-2.12-1.7.el6.x86_64.rpm -rw-r--r-- 1 silentm silentm 14815992 Jul 3 00:17 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-common-2.12-1.7.el6.x86_64.rpm -rw-r--r-- 1 silentm silentm 983372 Jul 3 00:10 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-devel-2.12-1.7.el6.i686.rpm -rw-r--r-- 1 silentm silentm 982972 Jul 3 00:17 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-devel-2.12-1.7.el6.x86_64.rpm -rw-r--r-- 1 silentm silentm 605080 Jul 3 00:17 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-headers-2.12-1.7.el6.x86_64.rpm -rw-r--r-- 1 silentm silentm 1416456 Jul 3 00:17 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-static-2.12-1.7.el6.x86_64.rpm -rw-r--r-- 1 silentm silentm 157512 Jul 3 00:17 /home/silentm/pxe-install/CentOS-6-x86_64/Packages/glibc-utils-2.12-1.7.el6.x86_64.rpm Thanks, Jerry

Selinux extra packages and compiled apps
by John Doe 07 Sep '11

07 Sep '11

Hey, I am in the process of trying (and convincing my colleagues) to learn/setup selinux as we switch to 6.0... Quick question: do I really "need" to install the setools/setroubleshoot packages or can I live without them? They want to install 80 packages (gnome stuff, gstreamer, gtk, tcl/tk...) and I would like to avoid installing all sort of graphical tools/libs on my lean servers. Can I just install setools-console by example? Is there a console only equivalent for setroubleshoot? If you know a must-have "selinux for dummies" like howto, apart from Redhat/Fedora doc or CentOS wiki, I am interested!Especially if it covers the case of many non-standard applications (the policy here is to use compiled apaches/php/mencoder/ffmpeg/..., all installed (with their data/logs) in a "/OURDIR" directory (but still use /var/run for the pids and a few others depending on the app), init.d scripts, logrotates, etc... Thx, JD

Running: yum list available | grep -i gmime shows results for CentOS 5, but not for CentOS 6. It seems to be needed by my pan. What should I do? Thanks, Mike.

mrtg 2.16.2 ipv6 on centos 6
by Florian 07 Sep '11

07 Sep '11

Hi, i'm running CentOS 6.0 on my server and installed mrtg from the rpm-package mrtg-2.16.2 . I also installed the depending packages perl-IO-Socket-INET6 perl-Socket6 .... mrtg works fine with IPV4-Addresses. When i specify a Target by IPV6-Address (or hostname resolving to a V6-address) mrtg fails. Here i have a small sample-config for V4 which is working: LogDir: /tmp ThreshDir: /tmp HtmlDir: /tmp ImageDir: /tmp LogDir: /tmp EnableIPv6: yes Target[bai-gw-i-oct]: ifInOctets.1&ifOutOctets.1:abc123@85.237.138.221 Title[bai-gw-i-oct]: Test MaxBytes[bai-gw-i-oct]: 100000000 ---------------------------------------------------- Here the same for V6 which fails. When running mrtg there is no snmp-packet sent to the network. LogDir: /tmp ThreshDir: /tmp HtmlDir: /tmp ImageDir: /tmp LogDir: /tmp EnableIPv6: yes Target[bai-gw-i-oct]: ifInOctets.1&ifOutOctets.1:abc123@[2001:b50:940f::f001] Title[bai-gw-i-oct]: Test MaxBytes[bai-gw-i-oct]: 100000000 # env LANG=C /usr/bin/mrtg /tmp/test.cfg SNMP Error: send_query: Address family not supported by protocol SNMPv1_Session (remote host: "2001:b50:940f::f001" [2001:b50:940f::f001].161) community: "abc123" request ID: 1156567655 PDU bufsize: 8000 bytes timeout: 2s retries: 5 backoff: 1) at /usr/bin/../lib64/mrtg2/SNMP_util.pm line 492 SNMPGET Problem for ifInOctets.1 ifOutOctets.1 sysUptime sysName on sni123@[2001:b50:940f::f001] at /usr/bin/mrtg line 2202 2011-09-03 14:13:01: ERROR: Target[bai-gw-i-oct][_IN_] ' $target->[0]{$mode} ' did not eval into defined data 2011-09-03 14:13:01: ERROR: Target[bai-gw-i-oct][_OUT_] ' $target->[0]{$mode} ' did not eval into defined data With snmpwalk (net-snmp-utils) i can reach the device via IPV4 and IPV6.

scim-bridge?
by m.roth＠5-cent.us 07 Sep '11

07 Sep '11

Anybody familiar with it, or what it's needed for? I've got at least one user (it's *very* noticeable with her) whose system is spamming /var/log/messages, to the effect of "Another agent is running...\nFailed to allocate the agent. Exitting" (complete with misspelled exiting). In googling, I've seen someone just removing the package. What, if anything, would that break? Oh, right, CentOS 5.6, KDE 3.5.4-1 mark

07 Sep '11

Greetings, I am tearing my hair at getting this to work under centos 5.5/Ubuntu 10.04. Any suggesstions (Repos, RPMs etc)? My MB Intel embedded NIC blow up after a lightning (Mumbai get _real_ heavy mansoon rains inter alia). I want this to make work under Centos 5.x (and 6.x subsequently who DVD I have been downloading with a pithy 128kbps connection). -- Regards, Rajagopal
