I am familiar with linux and have done some managing of servers before. I just tried to install centos 5.5 on a server, but after booting the screen was blank and my monitor said vga mode not supported. I found online to press ctrl+alt+F1, which allows me to see the rest of the boot commands. Then after I was able to see the boot commands it says enabling /etc/fstab swap, but never says ok or gets past that part.
View 2 Repliesthe boot of my server is stuck at the message "GRUB"
I've allready tried :
chroot /mnt/sysimage
grub-install /dev/cciss/c0d0
but with no improvement. What else can I try?
I am using CentOS 5.2 with GRUB booting a software RAID configuration. The first disk is md0 and is mirrored across sda1 and sdb1.I manually re-installed grub using grub-install and the machine will no longer boot off of the HD. The grub menu comes up, I can select my kernel the machine then jumps to loading the initrd and hangs.It will go no further. I have a live DVD that can boot from the HD. If I use that to first boot from the DVD, then specifiy the HD, it shows the same grub menu and then the machine boots fine w/o the initrd hang.I have tried re-installing grub but not been able to get the machine to work again w/o the DVD.
View 3 Replies View RelatedI just took delivery of a new computer, with CentOS 5 installed. It does not have a PS/2 keyboard socket, only USB. I get lots of strange "key stuck" problems - usually the shift key or the cursor keys (I guess I use them the most). Or sometimes key presses do not register. It makes it very difficult to use the machine.I have tried two keyboards (both of which work fine on other machines, or on this machine when booted with a live CD). The machine is an Intel i7. Are there any known problems with USB keyboard drivers in CentOS?

Plain vanilla, just installed.
When I boot, I get to the splash screen and it doesn't go into the default selection.
Could this be a Hardware thingy? The reason I ask is because I've had this issue happening with 5.2 on the same machine. I just formatted it completely and installed a fresh 5.3 i386 on it and I get the same behavior.

I've found a number of other entries about this, but they don't apply (the config files mentioned do not exist or whatever). My RHEL 4.x systems work differently, so the solutions I used there don't help either.In the course of some fussing around trying to get Virtual Box OSE to load, I apparently stomped on something so that when I log in now, I get the twm window manager--I was perfectly willing to have Gnome or whatever, but twm is a bit too light-weight for what I need.Anyone know where the magic config file or whatever lives in RHEL/CentOS 5.x?
View 3 Replies View RelatedI created a new Ubuntu 9.10 VM, and it installed fine. I then told it to upgrade, and was running it fullscreen and left it for several hours. Now the machine is stuck at full-screen, and Ctrl+Alt do not unstick it! I can see the mouse cursor, but cannot press Alt to bring up a menu or anything. I pressed Ctrl+Alt+F1 to get a console, and logged in as root and tried to kill-9 the process, (qemu-dm), but it won't die! Any ideas on how I can unstick the VM? I have lots of applications running and transferring data now, so I don't want to reboot the box for several days until the file transfers are done.
View 1 Replies View RelatedI 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?
I have successfully installed CentOS 5.4, and after choosing it from the GRUB menu, I am getting the following error message:1706-Smart Array Controller Extended BIOS Data Area Memory Corrupted.

View 1 Replies View Related3 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)?
I have a laptop that came with Windows Vista (64-bit) installed. I created a new partition and installed XP (also 64-bit) alongside it.Last night I shrunk my XP partition and created another new partition and installed Linux (CentOS 64-bit) on it. I made an error in judgment and didn't allocate enough space, so I need about 10 more gigs for the Linux partition. It boots up and runs, but I need about 10 more gigs of storage for the files I want to keep on the partition (and yes, they have to be on the partition, I definitely need to know how to do this, not a workaround)I went into Vista and shrunk the XP partition by 10 gigs, so now I have 10 gigs of free, non-partitioned space.
As it stands, when I start up the computer I get the GRUB boot loader. I can boot my Linux install or choose "Other" and be taken to the Vista boot loader. From there I can choose XP or Vista to boot.So, my question is... what is the best way to append the 10 gigs of free space to the Linux partition? Is this something I should do inside of Linux? I have the option to do it in Vista, but the partition shows up as "healthy" but without a file system type.I just don't want to screw up the boot loader, partitions or anything else.This isn't my area of expertise, so if anyone could give me a good suggestion or solid answer
have all ways been hiding in the background read not say a thinglets start well i look after 2 dell poweredge 2650 with 12 gig ram installed servers has been running fine onwell i though it was time to upgrade to 5 all went fine till reboot Memory for crash kernel (0x to 0x) not within permissible range ! well what i have been reading this is the norm for now What is mean by ignore it?

I managed to install Centos x86 for the first time, together with VncServer, SSH access, mySQL and Apache. Everything worked greater until I logged in remotely to the server from my Windows 7 machine using RealVnc. I manage to connect successfully and able to use the GUI remotely. However, when I press logout from the menu, the screen gets stuck on the funky blue and white curly background. It does not close automatically.
If I close it using the 'X' button and reconnect, I get in to same stuck screen. My only workaround is to login with Putty and type 'service vncserver restart'. Then I am able to connect again. But same thing happens when I do a logout.
I am trying to install CentOS 5.2 on an HP rp5700 desktop unit. These units were originally sold as a Point of Sales unit I believe, but HP also markets it as a high life cycle server for SMB market.I tried to load CentOS on this unit via CD (created from downloaded ISO of course). It presents the initial CentOS banner page and waits for the obligatory "enter" to continue. It begins the boot process up to discovering the PCI stuff and just locks up, no response. I have to power down to restart.Since this does not even get to the point of installing. I am at a loss what to do next. Has anyone had a similar issue with other PCs.The boot stops at the lineACPI: PCI Root Bridge [PCI0] (0000:00)

I've installed CentOS 5.5 on my Acer Aspire One D150. It uses the Intel integrated graphics chip GM945 which isn't supported "out of the box" by CentOS. My screen resolution has defaulted to 800x600, but it should be 1024x600. tried xrandr, and editing the xorg.conf file, and now have gone down the rabbit hole of trying to install xf86-video-intel and its associated dependencies (nested like Russian matryoshka dolls). I'm at the point of trying to install xorg-server, but am getting hung up by its dependencies on xproto and fontsproto, despite having installed them.

View 3 Replies View RelatedI had Windows XP Pro 32 bit and CentOS 5.4 installed on my Dell M6400 laptop and life was wonderful. Until I had to reinstall Windows. In the process, I reformated the C: partition of the drive where the Windows operating system was installed. I was careful NOT to reformat anything else. Now I cannot boot CentOS. The drive that has both the Windows and CentOS still shows the same partitions as were there before I reinstalled Windows, namely:
NTFS (C:) 171.82 GB
/boot 102 MB
(F:) 60.96 GB
is where my CentOS partition has all of my linux data and apps. I assume /boot should be the boot partition for CentOS I use Acronis OS Selector to show the partitions to boot. Now CentOS doesn't show as an option even if I go through the process of trying to detect a CentOS boot partition using OS Selector. I have researched this in the forums but have not found anything that was of help. There was a thread from someone who had trouble booting Ubuntu on a system with Windows Vista and CentOS but I did not see anything there that looked like it would help in my situation.
I applied the Kernel update that showed in the updater via the GUI.It now won't boot anymore.Memory for crash kernel (0x0 to 0x0) notwithin permissible range.WARNING calibrate_APIC_clock: the APIC timer calibration may be wrong.
