hi, Hardware: core2duo(E8400)/Intel Classic Board DG33FBC / 2x2GB I have been trying to install 5.1x64 for it's longterm support and xen but it just does not install till acpi=off is passed. works with one core after that and does not power off. Install stops at ACPI: PCI Root Bridge [PCI0] (0000:00) below is the reply from intel. ============================================================== Thank you for contacting Intel(R) Technical Support. Regarding your technical question, we regret to inform you that Linux* is not a supported Operating system for the Intel(R) Desktop Board DG33FB. Please review the following list for supported Operating systems for your Desktop Board. http://intel.com/support/motherboards/desktop/sb/CS-008326.htm Intel(R) Technical Support cannot provide assistance or drivers on operating systems that are not supported by the specific motherboard. Also, be aware that Intel(R) Desktop Boards do not support manually changing the IRQs, as the OS usually handles this. You can try disabling the onboard audio to check if you get rid of the POST error message. ============================================================== the dmesg from Centos5.1 install after acpi=off is here http://www.pastebin.ca/1043584 Fedora 9 does not seem to have problem and installs fine. the dmesg is here http://www.pastebin.ca/1043590 Maybe we need to wait for another year or two for upstream and centos to catchup. :) -- rm

netboot, vnc and no keyboard/mouse/monitor
by dnk 10 Jun '08

10 Jun '08

hey guys, I just created a custom netboot cd, that launches and loads from a http source, but connects to a vnc listening viewer. All in all, not hard to do, but what is different with this one is that it skips the media check, has no prompts and allows you to start the install on a machine that has no keyboard/mouse/monitor. Was handy for me as when i have some boxes to load, I just plug in power and ethernet in the corner (or where ever I have room) and go through the install. I know it also works with a cd as a source (if you use it from cd 1), and assume it would also work with a DVD (have not tested yet). If you would like it, I can add to the wiki if anyone would like it. DNK

Device Mapper and pretty names

How does one view the dm-{n} names wrt the actual dev names? I assume it involves dmsetup but I cant figure it out. I am using iostat to track some busy disk io and don't know which dm-{n} to watch :) Thanks! jlc

Help, PHP/Mysql connections are so slow.
by Pro Green European 10 Jun '08

10 Jun '08

Hi. I've got a new Centos 5.1 x86-64 server that uses PHP to communicate with MySQL5. On this server, PHP/Mysql connections are dead slow and unresponsive. It takes sometimes up to a minute to list tables in phpmyadmin for example. I've verified on the server that the issue has to be PHP/Mysql related. If I use a CGI based Mysql admin tool, communication is fast and there are no delays. The server is Xeon based and has 4GB of RAM. SElinux is enabled, and ModSecurity for Apache too. Disabling these two does not help. SElinux allows Apache to network connect. Some php.ini settings: =============================== safe_mode = On max_execution_time = 60 max_input_time = 60 memory_limit = 128M open_basedir is active, and there are no conflicts. disable_functions also contain several functions in order to secure server. allow_fopen_url is disabled =============================== Could there be a bug somewhere that is causing this slowness for PHP/Mysql connections. Feedback and tips for solving this problem will be greatly appreciated :) Regards, /PGE (aka mysteron) --- Link to forum post: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=14575&start=… --- Answer I've recieved and answered: Q: Sounds like the server is trying to do a reverse DNS lookup and timing out after a minute plus. Is DNS set up on the server correctly? A: Yes, DNS is working correctly. I tried with the IP address of the database server instead of its DNS name, but there is no difference, PHP/Mysql connections are still dead slow. ---

Software raid tutorial and hardware raid questions.
by drew einhorn 09 Jun '08

09 Jun '08

I remember seeing one with an example migrating from an old fashioned filesystem on a partition to a new filesystem on a mirrored lvm logical volume but one only one side of the mirror is set up at this time. First I need to copy stuff from what will become the second side of the mirror to filesystem on the first side or the mirror Then I will be ready to follow the rest of the tutorial and build and attach the second side of the mirror. Wish I could remember where I saw that tutorial. Want to embellish the example and stripe each side of the mirror. Understanding a mirrored pair of stripes, seems easier than understanding a striped pair of mirrors. But this seems like a place where counterintuitive results are not a big surprise. I can do mirroring and striping in lvm, mdadm, or a hardware raid controller. There are lots of configurations to ponder. What about recovery after a hardware raid controller? What are the chances of being able to replace the controller and start up successfully from drives? I know that assuming the failed controller did write bad stuff to the drives while it was crashing and burning. I would not be surprised if the controller firmware revisions had to match. I would be surprised but not astonished if the board hardware revision level had to match, too. I hope we are past those days. Anybody know about the LSI Logic MegaRAID 8480 Storage controller in particular. -- Drew Einhorn -- Drew Einhorn
