Latest chromium i686 - Illegal Instruction
by Trutwin, Joshua 27 Aug '13

27 Aug '13

Hi, I recently upgraded chromium on a 32-bit CentOS 6.4 system yesterday to version to chromium-28.0.1500.95-213514.i686. I then ran the chrome_pepperflash_copy.sh script, but my copy of the script was before it was modified to check the architecture so it downloaded the 64 bit chrome rpm and installed that version of pepper. I tried to run chromium but was greeted with "Illegal Instruction (core dumped)". I then noticed the 64-bit rpm was downloaded so I removed /opt/chromium/PepperFlash and completely re-installed chromium.i686. No go. So I then cleaned up /tmp, rebooted and removed ~/.cache/google-chrome and ~/.config/chrome. Unfortunately it is still crashing. I'm not sure if it has to do with the updated version or the botched 64-bit pepperflash installation, the script doesn't seem to do anything other than create /opt/chromium/PepperFlash and update the .desktop file. I ran an strace of /opt/chromium/chrome-wrapper and put it here: http://pastie.org/8272854 - it's always crashing on statfs64("/selinux", ....) - not sure what that means though. /selinux exists, selinux is actually disabled. Anyone else having issues like this? Thank you, Josh

Centos 6.4 problem with double spaced printing
by Billy Davis 26 Aug '13

26 Aug '13

We have a Centos 5.8 32 bit server that has been printing fine since we installed it. Recently, we also installed a new server with 64 bit Centos 6.4. On both servers, we print all reports with a simple 'lp' command. The new server prints all reports with double spacing. We looked at the text file that is being printed and found that it contains both '<cr>' and '<nl>' characters. On the 5.8 server, this does not seem to be a problem, but on the 6.4 server, it is. Does anyone know of a fix for this problem? Thanks BDavis

k3b -> cddb doesn't work
by ken 26 Aug '13

26 Aug '13

Copying a CD with k3b is no problem, except I want to include on my copy the cbbd data (from freedb.org). I've configured k3b's cddb section according to instructions at <http://www.freedb.org/en/faq.3.html#15> and read every article google could find about "k3b cddb freedb.org config", but still k3b can't manage it. Grip handles getting the cddb data just fine. I'm beginning to think that k3b is simply broke as far as this functionality is concerned. But I thought I'd ask here if anyone has found a way to make this work. tia for all helpful tips.

System Hang on busy NFS server
by James A. Peltier 26 Aug '13

26 Aug '13

On a busy NFS server I've started receiving the following error messages and the system hangs with high load but no work being done. The system is a Dell R510 with 12 x 3TB drives in a RAID-50 configuration. The RAID-50 device is a full disk LVM (no partitions) and one large (36TB) data volume and the system is running CentOS 6.4 fully patched for OS and firmware. Anyone have any hints as to what might be causing this. It looks to me like the system is starting to swap and then failing and then XFS starts to throw a hissy fit because it can't start allocating pages for it's buffers. Eventually then the system just deadlocks. I'm just looking for someone to confirm my findings and let me know if this is a bug or not. I've posted the dmesg output onto pastebin http://pastebin.com/YQbhsN6a Any help is very much appreciated! -- James A.

Is X79 Motherboard supported by latest "Centos 5.9" version?
by Steve Brooks 26 Aug '13

26 Aug '13

Hi Guys, In a bit of a pickle.. Is anyone running the latest "Centos 5.9" or earlier version with an Intel X79 based motherboard. I have a server which needs the motherboard replacing asap and I have a spare "Sabertooth X79". I have a machine with a "Sabertooth X79" motherboard to test on which boots up fine on on "Centos 5.9 i386" image from the troubled server. However the output from "lspci" (see below) seems far less descriptive than you normally see in "Centos 5" or "Centos 6". I am just a bit worried that this might imply lack of support. I do not need audio/firewire.. but need the essential to work memory, sata etc. Also I thought "i386" installs could not see more than 3 and a bit Gigs of ram? The test machine has 32G and meminfo shows MemTotal: 3574676 kB MemFree: 3146556 kB I would really appreciate any advice. Regards Steve e.g. The output from "Sabertooth X79" and "Centos 5.9" gives 00:00.0 Host bridge: Intel Corporation Device 3c00 (rev 06) 00:01.0 PCI bridge: Intel Corporation Device 3c02 (rev 06) 00:02.0 PCI bridge: Intel Corporation Device 3c04 (rev 06) 00:03.0 PCI bridge: Intel Corporation Device 3c08 (rev 06) 00:05.0 System peripheral: Intel Corporation Device 3c28 (rev 06) 00:05.2 System peripheral: Intel Corporation Device 3c2a (rev 06) 00:05.4 PIC: Intel Corporation Device 3c2c (rev 06) 00:11.0 PCI bridge: Intel Corporation Device 1d3e (rev 05) 00:16.0 Communication controller: Intel Corporation Device 1d3a (rev 05) 00:19.0 Ethernet controller: Intel Corporation Device 1503 (rev 05) 00:1a.0 USB Controller: Intel Corporation Device 1d2d (rev 05) 00:1b.0 Audio device: Intel Corporation Device 1d20 (rev 05) 00:1c.0 PCI bridge: Intel Corporation Device 1d10 (rev b5) 00:1c.1 PCI bridge: Intel Corporation Device 1d12 (rev b5) 00:1c.2 PCI bridge: Intel Corporation Device 1d14 (rev b5) 00:1c.3 PCI bridge: Intel Corporation Device 1d16 (rev b5) 00:1c.4 PCI bridge: Intel Corporation Device 1d18 (rev b5) 00:1c.5 PCI bridge: Intel Corporation Device 1d1a (rev b5) 00:1c.7 PCI bridge: Intel Corporation Device 1d1e (rev b5) 00:1d.0 USB Controller: Intel Corporation Device 1d26 (rev 05) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a5) 00:1f.0 ISA bridge: Intel Corporation Device 1d41 (rev 05) 00:1f.2 SATA controller: Intel Corporation Device 1d02 (rev 05) 00:1f.3 SMBus: Intel Corporation Device 1d22 (rev 05) 01:00.0 VGA compatible controller: nVidia Corporation Device 104a (rev a1) 01:00.1 Audio device: nVidia Corporation Device 0e08 (rev a1) 06:00.0 USB Controller: Device 1b21:1042 07:00.0 USB Controller: Device 1b21:1042 08:00.0 USB Controller: Device 1b21:1042 09:00.0 SATA controller: Device 1b21:0612 (rev 01) 0a:00.0 FireWire (IEEE 1394): VIA Technologies, Inc.

Fastest way of removing very large number of files?
by Rafał Radecki 24 Aug '13

24 Aug '13

Hi All. I currently have a problem on my backup server with very large number of small files in a large number of directories. I would like to delete them as fast as possible. Currently I use: rsync -a --delete /empty_directory/ dir_to_clean/ I've read that rsync will be faster than rm or find. Can you recommend something? I use an ext4 filesystem. Best regards, Rafal.
