CentOS 5 Hardware :: Installing CentOS 5.4 X86_64 On Adaptec RAID 3405

Jan 13, 2010

My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.

I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).

Whenever I try to install with: linux dd

I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.

I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"

This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.

CentOS 5 :: Centos 5.2 Installed On /dev/hda3, Won't Boot, Cant Find Grub Stage 2?

Nov 10, 2009

I just upgraded by box from Fedora Core 9 to Centos 5.2. Finally!I have a 500GB SATA drive, it's partitioned into three equal size slices, hda1 through 3. The old Fedora was on hda1, I installed the new Centos on hda3. I instructed the installer to write the MBR to /dev/hda, not /dev/hda3. Fdisk says I have sector 0 unused.First, the system wouldn't boot - it just looped through the BIOS, rebooting over and over again. The BIOS sees the disk, but it never loaded Grub. I tried re-running grub-install /dev/hda, and not I get a Grub Error 17 after stage 1.5 loads.

I can boot from rescue OK, the grub.conf man menu.lst look fine, it's pointing to "root (hd0,2)". It's either the BIOS that can't find the MBR, or the MBR can't find Grub.When I looked at the disk with fdisk after the install, hda1 was still marked bootable, hda3 was not, so I swapped bootable flags but that has not made a difference. I also appended the new grub to the old grub thinking I could get the MBR (if it is there) to load the old grub and thence find the new Centos, but that didn't work either.Mobo is an old Shuttle AK35.Any ideas? Did I mess up by not telling the system to put the MBR on /dev/hda3? Is there a way to fix this without reinstalling?

Installation :: Dual CentOS - Windows 7 Boot - Had To Delete CentOS Partition And No Grub Menu

Sep 19, 2010

3 partitions (in order): Windows 7, CentOS and shared data partition.

I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).

GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).

Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.

Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?

Red Hat :: Adaptec Embedded SATA HostRAID Controller 7e On CentOS

Jan 10, 2010

I have been trying for a few days to install CentOS 5.4 on an IBM x306 and I cannot get it to properly handle the Adaptec Embedded SATA HostRAID Controller. I have been working with Linux for a few years, but this is new territory for me. I typically use Debian-based distros, but I did some research on the IBM site and found out that RHEL is a supported OS for this machine. So, I decided to give Cent a try. I have some experience with Fedora, so it's not totally foreign to me.

Anyway, I'm a bit confused. Using the IBM RAID utility, I set up a mirrored pair of 1GB SATA HDDs. When I run the Cent installer, it sees the pair as a single array. I am able to partition the array and complete the install, but when I boot into the OS, it sees the drives as 2 separate devices, sda and sdb. I can pull either one of the drives and boot with a single disk, but it doesn't seem to behave as a mirrored pair. If I make changes on sda, they are not replicated to sdb. Also, I can't use the cli or GParted to format the existing space on the array. I get an error either way. I believe this is because Cent doesn't have a driver for the RAID controller, but I don't see why it would work in the installer, but not the installed OS.

My next approach was to start over and attempt to run "linux dd" at the start of the installation. I tried to find the driver for the controller on the IBM site so I could load it when prompted, but couldn't find a newer version than RHEL 4 Update 3 (I'm assuming this would coordinate with CentOS 4.3). I tried it anyway, but when I select the floppy during the setup, it tells me it's not for this version of CentOS. I read several times that there are .img files that might help me in the 'Images' directory of disk one, but I only see diskboot.img, minstg2.img, and stage2.img. I don't think any of these are what I'm looking for. I thought there was supposed to be a drvblock.img or driverdisk.img.

Hardware :: CentOS 5 Install Does Not Find HDs On Adaptec AHA-2940AU / Get That?

Jan 24, 2009

All installs attempts below are from CD

My hardware is
Tyan 1834 (VIA Chipset) dual P-III and 512 MB
Adaptec AHA-2940AU SCSI card with 3 Seagate drives
ATI Rage 128 AGP Video card

Tried to install CentOS 5 but did not locate any hard drives
(No drives listed at Partition Step)

Was able to install CentOS 4.4 and it located ATI card, and installed successfully and runs.

However, trying to upgrade to CentOS, also fails and does not find any hard drives (same error)
(also say "no video found, assuming headless" - but output still shown to screen - using 'linux text' install)

http://www.adaptec.com/en-US/_common/linux/ - lists Linux "supported distributions" including
CentOS 4.0/4.2/4.3 - but no mention of CentOS 5 (or could that page be too old?)

Want to use as test platform for custom software development, but it must match existing production machine CentOS 5 platform...
(Cent OS 4 could introduce a significant difference)

CentOS 5 Hardware :: Adaptec SCSI RAID 2100S Adapter On 5.5

Oct 10, 2010

Has anyone successfully used an Adaptec 2100S in a RAID configuration? Specifically, RAID1?

Drivers exist for earlier version of Red Hat, but building an using a driver disk results in the error:

Driver disk is invalid for this release of CentOS

CentOS does not recognize the adapter out-of-the-box as a HW RAID controller, but does recognize the individual disks.

I attempted to use software RAID, but the installer craps-out after a while and the screen locks up.

CentOS 5 :: Boot Setup From Partition That Is Formatted During Setup

May 5, 2009

Here is a thought experiment:

1. Copy vmlinuz and initrd.img from isolinux subdir into /boot
2. Adjust grub.conf to boot to that kernel
3. Reboot to setup
4. Format /boot (actually '/' ) during "fresh install"
5. Proceed with the installation-over-network

I see two possible outcomes:

1. The setup fails to reformat the drive, because it is "in use" by boot kernel

2. The partition is not "in use" and the installation succeeds

Why? Old cluster with broken CD-drives, lacking USB, and no separate /boot partition.

CentOS 5 Hardware :: 5.6 + Adaptec 5805Z And LSI Expander + Raid 6 Poor Performance

Jun 30, 2011

I installed on a Intel SR2612UR Server with integrated LSI Expander and a Adaptec 5805Z controller a Raid 6 Array with 12x 2TB Drives (2 ext4 Partition: 16TB, 2TB), but I get very poor read speed depending on the blocksize that I set it vary between 130 MB/s and maximally 170 MB/s which is really poor for a Raid 6 Array of 12 drives, on a similar Dell Server I get above 650 MB/s. The Adaptec Controller has the latest Firmware installed.

CentOS 5 :: Grub Doesn't Automatically Boot OS After Install, Hangs At Grub Prompt?

Mar 21, 2011

I have used CentOS for a while and have never run into this issue. I searched all over and didn't see a similar issue anywhere, I did an install of CentOS as a server (no GUI) with only the base. Partition is /boot ext3, size of 100MB. The rest of the drive is partitioned as / with ext3. This is being done on a CompactFlash card of 32GB in size. The BIOS sees it as an IDE drive.

When the install completes and the system reboots, the grub stops at the grub> prompt. There is no menu for OS options. If I do the following commands:
grub>root (hd0,0)
grub>kernel /vmlinuz-2.6.18-194.el5 root=LABEL=/
grub>initrd /initrd-2.6.18-194.el5.img
grub>boot

Slackware :: Dual Boot Slackware With CentOS Using CentOS GRUB

Apr 11, 2011

For various reasons, I have to learn my way around CentOS. I have an old computer (P3) with Slackware on it. I threw in a second HDD that I had lying around and installed CentOS to it. I was figuring that I'd just decline installing GRUB or point GRUB to Slackware as the second OS and end up with dual boot.

The CentOS install, though, blew right past that part with offering me any options. It put a small boot partition on the CentOS drive and now the box boots straight into CentOS.

I've spent the better part of the day trying to get GRUB to boot the Slackware drive and had no luck, though I've learned a lot about GRUB error messages.

By the way, CentOS uses GRUB v 0.97.

Question: someone could point me to a reference.

Here's the output of fdisk -l on that computer (/dev/sda is a 4GB SCSI disk that was originally the boot disk for Windows 2000 server on that computer):

Code:

Here's the currentGRUB file. I added the section about Slackware. I've also tried pointing it at:

Code:

I've also tried:

Code:

Code:

Slackware's LILO:

It's been six months or more since I used this computer. It's my experiment-er "play" computer and I had taken the HDD out to test a computer for one of the members of my LUG, so I can't remember exactly how I configured the LILO install, but, if I did what I usually do, I installed it to the MBR of /dev/hda. I have considered just blowing away LILO, but I'd be happier if I could just use GRUB to call LILO.

CentOS 5 :: Setting Up Initial Networking

Mar 18, 2010

I am configuring a new installation of CentOS 5.4 with the goal of setting up a server. Ive been through the installation and set up everything that I thought that I had to setup. Im getting into CentOS because my work utilizes this distribution. I do have some debian experience, and I have used Ubuntu on both server and desktop platforms.

Now, when setting up Ubuntu, I found that I was able to get networking up much easier. During the initial installation it had asked me to choose between DHCP or manual configuration. As this is going to be a server I want it setup with a static IP. But for some reason no matter what I do I can not get the machine connected. I go so far as trying to do a 'yum update' and I can not make a connection.

A few things Ive noticed that might be applicable here . . . . .

For DNS servers, I am unsure exactly what I need to put here. My ISP is Cox. I am not sure what NS's to put there for them, so I thought that I would be able to use third party DNS servers such as OpenDNS or the Google Public DNS. I know that I have setup my debian server like that with no issues. Also when setting up my debian server it prepopulated certain areas that I am required to fill when setting up CentOS. Example, when setting up localhost.localdomain -- I would choose my hostname and local domain was prepopulated as ph.cox.net. I dont know if this is something that I have to use, or if it would change if I am using third party DNS.

My resolv.conf file looks like this

search ph.cox.net
nameserver (IP address of third party dns either opendns or google)
nameserver (IP address of third party dns either opendns or google)

CentOS 5 Hardware :: Triple Boot Setup - IRQ Conflict

May 22, 2009

Basically I have a triple boot setup on a mac pro tower. Windows /osx /centos 5.3 everything was great until I tried setting up my Wacom. I did get it setup but in the process revealed a problem I was having that I didn't notice until this point. Mind you my system boots perfectly everything runs perfectly except I believe my DVDrom and rear usb ports are trying to share the same IRQ and from what it looks like they don't want to play nice with each other. Eventually CentOS kills the IRQ thus killing both devices. Everything works fine on the windows and mac osx side. I have tried unplugging and replugging the DVDROM, I wanted to try another ide channel but the motherboard only has one. I have changed the device from auto to master to slave. When the DVDROM is removed i have no IRQ errors in my dmesg. I forgot to add that adding IRQpoll to my grub boot pretty much destroys the system.... hard lock within 20 seconds of loging in. In CentOS, is there anyway that I can force the DVDROM to it's own IRQ?

Handlers:
[<ffffffff8000d346>] (ide_intr+0x0/0x1df)
[<ffffffff801e65ca>] (usb_hcd_irq+0x0/0x55)
Disabling IRQ #98
hda: lost interrupt
ide-cd: cmd 0x3 timed out
hda: lost interrupt
hda: request sense failure: status=0x51 { DriveReady SeekComplete Error }
hda: request sense failure: error=0x54 { AbortedCommand LastFailedSense=0x05 }

CentOS 5 :: Procedure To Restore Initial Installed Configuration?

Jun 18, 2009

I am looking for a procedure to recover the initial installed state of my system with out over writing user data areas. The install procedure has the phrase "will remove all linux partitions" which interpret to mean data partitions, not just /bin and /. Additional background - Was attempting to build a 32 bit cross compile of Mozilla/Firefox on a x86_64 configuration and had a conflict with libgl. Online advice was to remove duplicate libgls from the system (that was bad advice). This led to running yum update.

When I restarted the system I know longer had wireless networking, ntfs mounts and possibly other features I had installed. Further, attempts to update, re-install, erase and reinstall have had no effect on the situation. My assumption is that I need to start with a clean install - which will be about 10-20 hours to reset all the additions I made. But I don't see another solution.

Is there a script that is run by adduser, or a list somewhere of the files that are needed for KDE Desktop to work correctly? Or, do I delete or rename certain files and then, what executable do I run to get the Desktop?

CentOS 5 :: GRUB Won't Boot Windows?

Jun 9, 2009

OK Here's how it was:

1 I have 2 SATA drives - The first (/dev/sda) is a Windows only drive The second (/dev/sdb) has a Linux Partition + Swap (sdb1 and sdb2) of 40GB and the rest is an ntfs partition(sdb3)

I used to have Ubuntu on the Linux partition that nicely detected Windows, installed the bootloader on sda and correctly set up the boot options, everything "Just worked"!

Since I'm studying for RHCT I decided to wipe Ubuntu for CentOS, Centos also nicely detected an "Other" operating system, but it decided to install the bootloader to sdb. After a few minutes of frustration I realised this had happened and changed the BIOS to boot sdb instead of sda. While GRUB now happily boots CentOS, When I select Windows it just hangs.

I tried grub-install /dev/sda and changing the BIOS to boot sda, all I got was GRUB GRUB GRUB printed on the screen and then nothing happens.

get both OSes to boot? I suspect that windows doesn't like it if the bootloader is on a different drive to it's own partition.

UPDATE

It's OK I tried again to grub-install /dev/sda and changed the /boot/grub/device.map file and reversed the hd0 and hd1 entries, i then edited the menu.lst file and did the same, it now boots both OSes ok. The only downside is the nice CentOS background is missing in Grub now :)

CentOS 5 :: Booting CentOS V5.2 Fails With GRUB Error 13: Invalid Executable Format?

May 5, 2009

I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.

- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.

After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

General :: CentOs 5.3 - Grub Configuration For Boot Order

Feb 11, 2010

I clone an drive with CentOs 5.3 from a drive connected to ATA0 device 0 of an ATA controller to an identical drive connected to the same ATA contoller ATA1 device 0. No matter what I do it boots from ATA1 device 0 and I need to be able to control which one it is booted from. When I have puppy linux on one drive and CentOs on the other drive I can control the boot thru the system BIOS either way no matter if puppy is in ATA 0 or 1. So its not a BIOS issue. It appears (to me) to be a grub configuration issue. Since the 2 drives are clones they both have VolGroup00. I think grub loads from the last VolGroup00 found.

Here is my grub.conf file:
# grub.conf generated by anaconda

CentOS 5 :: Grub And Dual Boot - Reconnected HDD1 But XP Is Disappeared

Aug 5, 2010

1 I have XP installed on HDD1 (SATA 200 Gb master). Now I installed Cetos 5.5 (use 4.1 Gb DVD1) on the second drive, HDD2 (Seagate STA 40 Gb slave.) I didnt fund the option for selecting boot location during installation, just selected second drive. I think this is my first mistaking. The Centos can�t boot up after initial installation. I disconnected the HDD1 (XP drive.) Then finished Centos install. � Second mistaking.

2 After that Sentos installed, I reconnected HDD1 but XP is disappeared. The grub.cfg shows about XP as:
Title other
Rootnoverity (hd1,0)
Chainloader +1

3 For finding XP I disconnected HDD2 (Sentos), but XP can�t be started. This message is shown up:

Just wait 5 seconds for normal startup! Boot: could not find kernel image:vmlinuz

4 I think that stuff was written by grub. I decided to get rid of them then reinstall all. I tried to deleted and create new partition, format c:, fixmbr, and fixboot, then install XP on c:. But above message still shows up when boot machine. I have to use XP install cd to start Windows XP.
