Ubuntu Installation :: How To Load Additional Modules (Server)
Sep 17, 2010
I've been playing with some intel server board and they provide a type of fakeraid which is called Embedded Server Raid Technology 2. Since Intel officially support RHEL and SLES on their servers, they provide drivers/modules for this fake raid (which supports raid 0, 1, 5 and 10). I have installed RHEL before on these severs and redhat's installer has the ability to load additional modules (via a boot command linux dd).
While intel doesn't provide the modules for other operating systems, they provide a library where people can build their own module for their kernel. I managed to build this module called 'megasr' (for now I've built it for kernel 2.6.32-24-generic which is my testbed at the moment but I would eventually build it for box i386 and amd64 for both server and desktop versions) and load it on a system which is installed on a single drive.
We are able to load it successfully and see the raid 5 as a single volume and access it (partition, format and copy data to it) and all its functions (work in degraded mode, rebuild, etc) work fine but my main goal is to actually install such volume as my main boot volume (similar to how its possible with RHEL or SLES). Is this possible? Load additional modules during the installation that will be present after the installation is finished?

Tonight I installed ubuntu 10.10 (32 bit) on an external usb harddrive with a dvd I burned and I used my older desktop. I disconnected all internal and external drives first so everything had to be put on the usb drive I selected (only option available). I used the option to load extra software, use the entire hard drive, and let the software do it's thing. I basically had no options where to put things and it didn't have much choice.
When I boot the usb drive on my laptop (win 7 64 bit) by telling the bios to boot to it first... I get an error: modprobe: FATAL Could not load /lib/modules 2.6.35-22 generic modules No such file or directory. This message appears twice and then it does boot into ubuntu and seems to work fine. I'm new to this OS so that is an uneducated guess but the things I have done seem to be working. So exactly what is this error referring too? Is there a way to fix the problem or do I just ignore it.

I was using v 8.10. It came to its end of life and I felt compelled to upgrade. I upgraded to v 9.04. All seemed well, but then I discovered that I had no sound. As a test, I booted up with the v 9.04 CD, using it as a live CD. I had sound, so it seems as though it should be possible for me to have sound from my upgraded v 9.04 too, provided I can make the necessary changes to it.
When using the live CD and opening the volume control, I get as the listed device "HDA ATI SB (Alsa mixer)". That doesn't appear when I open the volume control using my upgraded v 9.04. Instead, it says "Playback: Null Output (PulseAudio mixer)". Also, when I check for loaded modules when using the live CD, I get many with snd in their name, but nary a one when using the upgraded 9.04.
Is there some simple way for me to load the same modules in the upgraded 9.04 as are loaded by the live CD? I tried to figure out the answer to this by reading other threads, but was simply overwhelmed by the volume of material and often wasn't sure to which version of Ubuntu it applied.

I have two Red Hat entreprise Linux 5 servers running the same applications, my goal is to load balance the incoming traffic between these two servers without adding an additional hardware as load balancer, the incoming traffic is basically Web traffic and on the servers, Apache and PHP are running. Red Hat solutions that I found are:
1- LVS
2- Piranha
3- Red Hat cluster suite.
Can LVS run on one of the real servers (or both servers, for redundancy issues) and load balance the traffic between its server and the other one? If yes, will LVS has a big impact on the CPU/memory usage? How can I estimate this usage if I know how much traffic is coming and the HW specs?
Can I install Red Hat cluster suite on these two servers, and configure it in a way that the virtual IP is on different server for different request (taking in consideration that the same session will be always served by the same server)?Finally, is there any other/better solution that can fit my requirements to load balance the traffic without additional hardware?

I know how to get root access in iConnect and ssh into it. I wanted to know whether we can install any applications on it using the package manager and what package manager it supports, like apt(debian based) or is it based on some other distribution.

My apache and wordpress were running fine till this morning. I ran updates via webmin,though I wasn't sure what those updates were for.
Then when I tried to access mysite.com, index.php downloads instead of opening.
I tried some troubleshooting and followed a form where it was advised to enable mod php5, so I did a2enmod php5 and tried to restart apache. Since I get this error Cannot load /usr/lib/apache2/modules/libphp5.so into server.

How do I get modules in the Kernel to load automatically at boottime? I''m specifically trying to get i810fb to load during the boot process. In Ubuntu, I just had to edit a file and update my initramfs. How do I do this in Fedora?

Yet another problem I have. Suse is taking a while to learn but I swear I'm getting there. Can pritty much do everything by CLI now. I'm trying to run VMware Workstation 6.5 on OpenSuse 11.2, Gnome. I had it running fine but then needed to do a system re-install and upon installation this time I get a error saying it's is Unable To Build Kernel Module and reffers me to a error log. The error log says:

I use Debian 5.0.6 32-bit through VMware workstation installed on my Windows Server 2003. I just simply installed it from CD-1 and I use Directadmin on that.
I need a lot of iptables commands for blocking but I keep getting missing module errors on that one, I did lsmod | grep -i iptables to see there are no modules. It should have been installed by the disc image but I don't know why it didn't. So I now want to know how to get those modules required by iptables.

After a hiatus I found my machine to be down, but upon turning it on I get significant errors and dropped into emergency mode (see below). This machine wasn't very up-to-date to begin with, so I'm having difficulty determining the order in which to proceed. A couple naive checks and updates on my part are not working. The file system appears to be intact enough to "cd" around and "ls" to see that my files are all (seemingly) there. But the kernel modules aren't loading which is, you know, a problem.
The state I find it in is that it will begin booting to Linux 3.2 (which I know is no longer supported in testing, see below where I tried to update to 3.16), but fails quickly and puts me into emergency mode
Loading, please wait...
megasas: INIT adapter done
systemd[1]: Failed to insert module 'autofs4'
systemd[1]: Failed to open /dev/autofs: No such file or directory
systemd[1]: Failed to initialize automounter: No such file or directory
systemd[1]: Failed to set up automount Arbitrary Executable File Formats File System Automount Point.
...Then several drives show up as clean....
Running "journalctl -xb" shows that it can't mount the module even though it's there on the disk:
... systemd-modules-load[259]: could not open moddep file '/lib/modules/3.2.0-4-amd64/modules.dep.bin'
... systemd-modules-load[259]: Failed to lookup alias 'firewire-sbp2': Function not implemented
... systemd-modules-load[259]: could not open modeep file '/lib/modules/3.2.0-4-amd64/modules.dep.bin'
... systemd-modules-load[259]: Failed to lookup alias 'loop': Function not implemented
And yet, if I 'ls' that modules.dep.bin file, it's right where it's supposed to be, for the appropriate architecture and everything.
After that (in the journalctl output), it shows several things start up, but systemd-modules-load.service fails:
.. systemd[1]: systemd-modules-load.service: main process exited, code=exited, status=1/FAILURE
.. systemd[1]: systemd-modules-load.service: Failed to start Load Kernel Modules
...and lots of things fail from systemd-udevd: failed to execute '/lib/udev/socket:@/org/freedesktop/hal/udev_ev_event': No such file directory.
"uname -a" shows
Linux <my hostname> 3.2.0-4-amd64 #1 SMP Debian 3.2.32-1 x86_64 GNU/Linux
I tried updating via apt to the Linux 3.16.0 kernel, but grub wasn't finding it in a way that effects the boot process, and no appropriate "vmlinuz-" file appears with the others on the boot partition. So, I tried switching to grub2 but the update-grub command produces many errors.... For now, grub2 still (attempts to) load the old kernel (3.2) with the same results as I was getting with the old grub-legacy.
Regarding the module-loading features, running "lsmod" shows about 30 lines:
Module
ext3
mbcache
jbd
dm_mod
usbhid
hid
[Code] ....
...I'm at the limit of what I know to check and/or try.

I was wondering how can I determine among the modules loaded at boot which of them are really necessary and which are not, in order to reduce the boot process time and have a more "elegant" system start.
I know this theme is a little bit of complicated because it depends of the user's point of view and demand a high knowledge of which things are happening in your system but I need somewhere to start improving the performance of my debian system.

I am trying to setup Slacware 13.1 x86_64 to a encrypted partition. I used the README_CRYPT.TXT howto : [URL] At the step when I create an initrd.gz I get this error: Quote: ERROR: No /lib/modules/2.6.33.4-smp kernel modules tree found for kernel "2.6.33.4-smp"
I tried to look into the directory and there was only modules under 2.6.44.3. So I tried to change the command into: Quote: mkinitrd -c -k 2.6.33.4 -m ext3 -f ext3 -r cryptroot -C /dev/sda2
This command was successful, but I don't know if this is alright. I made the changes in lilo.conf, add initrd = initrd.gz. This is all on unencrypted /boot partition. The boot=/dev/sda1 I also set for the unencrypted boot partition. When I boot the system I get a kernel panic:

I am using NFS to mount large LUNs from my SAN.I have one already setup and configured. I am adding an additional partition from the same SAN but I am confused on the setup. I know the LUN is connecting to my NFS server correctly because I see it listed in my /proc/scsi/scsi as an additional LUN. What I don't see is the drive being displayed in fdisk -l. I did notice one thing though, when I disable the host mapping from the SAN, my disk information changes from /dev/sdb TO /dev/sdc (see changes below)
Without host mapping to SAN:
Disk /dev/sda: 13999.0 GB, 13999026470912 bytes
255 heads, 63 sectors/track, 1701951 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I had a dual boot Kubuntu 9.04 - FC 11 and decided to upgrade to Kubuntu 9.10. Recalling that I had issues with my ATI card drivers when I installed Kubuntu8.10 on my laptop, I decided to install the latest ATI Catalyst drivers. After the installation was complete I received a message warning me that if the X server fails to load I should run "aticonfig --initial -f". Indeed the X Server didn't load (after I logged in the screen flushed and went black). So I reinstalled Kubuntu 8.10 from a CD I without formating the respective partition. But the problem perists, X server fails to load. Even worse my menu.lst file has been changed and I can't boot FC11.

I've got two files. They both contain package names. Is there any way I can go through the package list on one file, and search to see if each package exists in the other file? What I'd want to do, is if the package name is found in the the main file, then go to the next line. If its not found then print that package name to another file.
I know you can use diff, but it doesn't seem to be that straight forward. As I understand it diff searches line by line, so if line one doesn't match line one in another file, then it prints it out. That's not exactly what I want.
I just really need an easy way to filter out the additional packages that exist on a new server. If I have a list of packages that aren't on the original server, then i can just delete them.
Not sure if I've made any sense but there must be a quicker way to do what i need to. It would take me ages to scan manually through the package names in each list, and highlight the ones i dont need.

I recently brought home an old Compaq server from work. I was told that it works fine. When I brought it home, I tried installing Ubuntu 9.10 server from a cd. While it's trying to install, I get the message "Installation step failed. An installation step failed. You can try to run the following item again from the menu, or skip it and choose something else. The failing step is: Load installer components from CD." I turned off the computer and tried it again several times. Each time the same message appears.
