CentOS 5 Hardware :: Enable New Libata Library Without Recompiling Kernel?
Sep 9, 2009
I use CentOS 5.3 with kernel 2.6.18-128.1.6.el5 for Clonezilla. It would be simpler for me if any of IDE or SATA drives detects as /dev/sdX device. Because when I cloning computers with Clonezilla it is matter which type of drive connected to cloned computer. So I must firstly clone computers with IDE drives, after that with SATA drives. If all drives would detected as /dev/sda I would can clone all computers at once! Is there simple way to enable new libata library without recompiling kernel? Is there already compiled kernels with this feature?
if i wanted to just download and install a module, how does centos have it where i don't have download the source and recompile the whole kernel withthe module enabled? i read about install kernel-devel but nothing much more on using it. for instance, if i wanted to download ext4 module and have the kernel use it?
If I compile the kernel once fully and if I wan't to make a minor change how do I do that without having to go through the whole recomiliation? Commands like "rpmbuild -bb" and "make rpm" seem to recompile everything but it should just compile the changes I made.I'm using Fedora 12 with the latest stable kernel.
I only have basic experience recompiling a Linux kernel, and I have a question about adding dynamic modules.In case I want to add a brand new module, do I need to recompile the kernel to include a reference to that new module, or is simply compiling a kernel with generic support of dynamic modules all it takes to add whatever modules I need later on, without recompiling the kernel and rebooting the host?
i have recompiled kernel on my netbook (lenovo s10-3t).suspend works correctly but then i cannot wake up. i think i just missed some kernel options.what options must be set for suspend/wake up?
How do I force recompilation of the kernel .deb packages. After a small change I make to the sources without having to clean the sources and recompile the whole kernel again?
Code: Select all$ fakeroot make -f debian/rules.gen setup_i386_none_686 $ fakeroot make -f debian/rules.gen binary-arch_i386_none_686 binary-indep
Calling the second command again does not recompile the modified code, just recreates the .deb packages.
If I use:
Code: Select all$ make -f debian/rules clean before the build command, then it will recompile everything which takes ages.
How can I force recompilation of the files/objects I changed (and dependencies)?
I use this guide: [URL] .... ('Building only a single kernel variant' section)
I just up-graded to the latest version of the stable 11.4 64bit kernel on my laptop and it appears that the repositories have not compiled the VirtualBox driver module for the current kernel ... When I make /vboxdrv setup the message is:
Recompiling VirtualBox vboxadd kernel module, NOT. It has been packaged
I think this means that the installed module will not recompile has it was packaged. My kernel version is the lattest :
2.6.37.6-0.5-1
And my VirtualBox was installed from the Virtualization repos (4.0.8.11-1) even made the Vendor change and all. The version Before the lattest (4.0.4-1.6) did not work either. With the same problem. It is very easy to install VirtualBox from the Sun site and every time there is a Kernel up-date one can always make /etc/vboxdrv setup.
I'm currently upgrading my clients' CentOS 5 installation to use httpd-2.2.14 as we need it for the server to past some of the Hardware checks used in the PCI [Payment Card Industry] security test. I was basically wondering if anyone had the standard CentOS 'configure options' for building httpd/Apache so I could copy them to ensure it is a straight replacement for my existing 2.2.3?
I have read that when using xfs with lvm2, prior to kernel 2.6.29 write barriers are by deffault disabled.As i want to migrate /home to xfs (and create a external partition to hold some data in xfs too) i was thinking in compile a custom kernel 2.6.30 or higher from [URL].I have read the wiki, all the warnings , and that for compile a kernel.org kernel you should use the Linux Kernel in a Nutshel guide/book. But i don't really know if would worth do that only to have write barrier support , more when in one month i will buy a ups to be sure i can shutdown the pc well if the power goes out.Should i enable write barriers on xfs with lvm2 ,although going to have a ups ?
I'm using Amarok 2.3.2 on openSUSE 11.3 with KDE 4.4.4r3. How can I enable DAAP sharing of my Music library so that I'm able to access it in Rhythmbox from my Linux Mint 9 desktop?
I am trying to compile a kernel 2.6.31-12 in my machine which is running ubuntu 9.0(kernel version 2.6.31-14). I don't have internet connection on that machine. I somehow downloaded the kernel sources on some other machine and copied it the my PC which is running ubuntu.I have installed the kernel sources (.gz file) by un-zipping and un-tarring the archive. For compiling the kernel I am following the traditional approach:
1. make oldconfig ( make menu config is not working ) 2. make dep 2. make clean 3. make bzImage 4. make modules 5. make modules_install 6. make install 7. Modify the /boot/grub/grub.cgf
I didnt encounter any error in the above steps till step no. 6. However in the step 7, I am not getting the /boot/initrd.img-2.6.31.12 file which is needed for the ramfs. However I am getting the vmlinuz file in the /boot.
In another thread I shared how my system occasionally freezes. I found a solution in which I forced the drive connected to sata port 1 (ata1) to run at 1.5 Gbps and let the second drive connected to sata port 2 run at 3.0 Gbps. I have multiple systems on this machine. When I boot into Slackware 12.2 with the 2.6.27.58 kernel.
I see this in dmesg: ata1: FORCE: PHY spd limit set to 1.5Gbps ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xe000 irq 23 ata1: SATA link up 1.5 Gbps (SStatus 123 SControl 300)
Looks okay. When I boot into Slackware 13.1 I see this in dmesg: ata1: FORCE: PHY spd limit set to 1.5Gbps ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xe000 irq 23 ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
Further, when I boot into 13.1 the freezing problems return. Therefore I suspect the drive is running at 3.0 Gbps. 1. Why isn't libata.force working? 2. How can I know what speed the drive is running?
I get some errors in dmesg and a delay as libata probes and tries to negotiate with my eSATA enclosure.
Some backstory to this adventure:My mainboard is an MSI K9AGM2-L with the AMD SB600 chipset providing the AHCI SATA controller for four ports, two of which (#s 3 and 4) are available.
A Rosewill RCR-AK-IM5002 internal card reader (manufacturer page missing) provides a SATA-to-eSATA adaptor port.
I wish to use a SAMSUNG Spinpoint M7E HM641JI 640GB 2.5" SATA hard disk drive externally. First, I had a Vantec NST-260SU-BK 2.5" SATA to USB 2.0 and eSATA enclosure. As explained in this forum post, all seemed well at first. But even though I got absolutely no visible errors, I could see (through hash checking and byte-by-byte comparisons) that writing (copying) to the external disk was not happening correctly. After exchanging the enclosure several times, I finally noticed that the retailer had a different (generic) brand, so I got one of those instead. (The particular unit I got was missing its screws; had a protrusion in its casing that obstructed the circuit board's seating; and caused even my mainboard's firmware to lock up when it was probed, twice, on each boot. A replacement with the same model remedied those three issues.)
Now we come to the present. The Comkia MM-G3BK-SUE MobiMe G3 2.5" SATA to USB 2.0 and eSATA enclosure (manufacturer page missing) doesn't seem to exhibit the writing issue (yet) -- hurray! However, it causes libata to struggle for fifteen seconds or so trying to connect when it is plugged in. (It also causes openSUSE to stall while booting for that reason.) Here is the output from dmesg:
I'm using a RHEL5/Centos5 variant. After struggling with various 2 TB hard drive failures, I started using the Hitachi Deskstar and Ultrastar models, and had none of the earlier green feature related or QA problems I had with all others. However, I began seeing SATA controller freezing under heavy loads, like large rsync mirror operations. My controller is an on-board ICH7R running in AHCI mode. The symptoms are that the drive goes off line and begins to log thousands of SMART errors for Spin-Up Retries. Analysis confirms that the drive is 100% OK after, except for the huge SMART log. This happens on two servers, and multiple drives. Changing the drive to 1.5 Gbps interface speed reduces the problem greatly but does not eliminate it.
I'm working with Hitachi engineering on this, and their only theory is that it has to do with "non-zero buffer offset". Apparently this is a feature of NCQ to receive data out of sequence, and Hitachi says that ICH7R is supports NCQ but not this feature. I am told that BIOS is supposed to filter offending commands but BIOS vendors sometimes err. An alternate is to filter them at the driver, which I believe is libata. Does anyone know anything about this issue? Where might be a good place to make a query about this, with regards to libata? I've contacted the motherboard vendor about the BIOS issue, but I'd like to look into libata also.
how to make the SATA port as 1.5G or 3G, 6G by command line operation without reboot PC by editting grub.conf?I need to switch the SATA port as 1.5G <-> 6G without reboot.
I installed Tikiwi 3 beta 4 on CentOS 5.3. While installing, installer reported it could not find GD library (graphics). I tried installing all GDxx. Same result.
Anybody know which library Tiki is looking for? Or Tiki bug?
I'm trying to install the GD library from the Add/remove software app, but it will not install because it says that it can't resolve a dependency "PHP-common", however, this IS installed, yet it keeps giving me this error. Is there a work around to this or a way to fix the dependencies problem?
I've been happily running Centos 5 (in fact kernel 2.6.18-92.1.22.el5) for a while now.Today, I tried to install Audacity and although it installed OK, when it ran, it came up with 'library incompatibilies'.I looked around and found someone who had installed using ....
I installed these and Audacity ran OK ....However, then the problems started.I'm now getting a message from the software updater telling me that 185 packages need updating! I've tried letting it update and it downloads, checks dependencies and then stops without any upodates. Each reboot tells me the same thing.It seems obvious that no updates are in fact needed and I'd like a way ofstopping the message appearing.
I am trying to add some functions to a Postgresql database. The functions use a shared library which they think is: /usr/lib/pgsql/postgis-1.4.so They say: "ERROR: could not load library "/usr/lib/pgsql/postgis-1.4.so": libgeos_c.so.1: cannot open shared object file: No such file or directory"
I cd to /usr/lib/pgsql/ and do an ls. postgis-1.4.so is there. libgeos_c.so.1 is as well (and it's in /usr/lib/ )
Both the files seem to exist. I cannot copy either of them (cp says "cannot stat '[file]': No such file or directory".
I recently upgraded to php 5.2 using the testing repository. All went well except for one extension.

It seems the file libdb does exist. man dbopen displays man page for dbopen. I also tried to ln -s /usr/lib/libdb.a and libdb.so /lib dir but all were in vain.
I was wondering how/if it was possible to edit the min. version number of a depen for a .deb package. For example lets say my package says it needs libc6 2.7.1 or higher but I want it to be 2.5.1 or higher instead. Can I make this change with out having to recompile the .deb package?
On a new install of CentOS 5.3 I am trying to make the Logitech MX Revolution mouse work (I did actually succeed in configuring it by BTNX on my previous machine, but can't make btnx work now...). I am following the instructions from [url] works. However, when installing the xmacro package it complains about a missing library: libstdc++.so.6(GLIBCXX_3.4.9)(64bit). The library is available in Fedora but not in CentOS. I guess installing the Fedora library is unwise...?
Does anyone know how to make xmacro work?
Also, in xorg.conf it seems (from other posts etc) using the evdev driver for the mouse would be advisable.
However, when I change from [driver "mouse"] to [driver "evdev"] X cannot start. In the xorg.conf logfile (/var/log/Xorg.0.log) it seems like the evdev driver is not compiled:
I don't really understand the error, but it seems to me, that the evdev driver is not compiled... The evdev driver should, though, be installed (through the package xorg-x11-drv-evdev-1.0.0.5-3.el5.x86_64)
If this is right, how, then do I compile the evdev driver?
I have tried to compile the fakeroot 1.15 on centos 5, but it always failed to load the shared library libfakeroot.so file. I tried compiling 32 as well as 64 bit version of library but always it failed to load the library and give the following error:
ERROR: ld.so: object 'libfakeroot.so' from LD_PRELOAD cannot be preloaded: ignored.
I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
Anyone can tell me how to enable and config auditd in linux kernel 2.6.9-5.EL. I have only found command auditd and auditctl in server that run kernel 2.6.9-5.EL. I ran auditd & and can saw auditd ran in my server. But I couldn't do anything with auditctl, no status, no rules, nothing :| . I tried to find audit.rules or auditd.conf but that nothing I can find.
