Ubuntu :: Internal Disk In A Running System Usb-booted System Does Not Result In The System Detecting The Disk

Feb 27, 2011

My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.

How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?

Oct 28, 2010

Booted up system and it stated please insert system disk press any key.So it sounds like my startup got corrupted? I running centos 4.5 on it (old yes) Is there a repair I can perform by a disk? Would it matter if I chose i386 or x86? I cant remeber which version was installed on it.

Hardware :: Adding A LVM Hard Disk To A System Already Running/using LVM?

Aug 9, 2010

I have two systems, both having file systems running on LVM. System No 1 has 2 PATA HDD (40 and 80 GB) running linux on LVM. System 2 has a single SATA HDD (300 GB) which again uses LVM. What i was trying to do was to add the two HDD in system 1 to system 2, possibly with little or no data loss. So i connected the PATA drives from system 1 to system 2 and booted up. The system booted up to the openSUSE 11.3 splash screen and stopped after scanning the HDDs. Frankly i never expected openSUSE to try n auto mount the new drives. I think the problem was caused because both the systems had VG and LV of the same names. Can the volume group be renamed, maybe from a live CD or somthing?? System 2 is not boot able now.

Ubuntu Installation :: 9.10 - Non-system Disk Or Disk Error With Manual Partitions

Apr 9, 2010

This is the third 9.10 install to do this on two different laptops, so wondering what's up...

In both cases, the goal was to leave a large chunk of unpartitioned disk after the Ubuntu partitions, for a second OS install or a filesystem Ubuntu cannot create like NTFS.

When I install with manual partitions, the system can't boot and asks for me to insert a system disk and press any key. When I reinstall telling Ubuntu to "use the entire disk" it then works.

First laptop, first try:

Remainder of the 500GB disk is free space.

Fails to boot, "insert system disk".

First laptop, second try without the /boot partition:

Remainder of the 500GB disk is free space.

Fails to boot, "insert system disk".

"use entire disk" works perfectly.

Second laptop, first try:

Same thing, non-system disk or disk error, insert system disk.

Second try "use entire disk" is currently in progress but I expect the same to happen.

Ubuntu Installation :: Migrate Working Single Disk System To Existing RAID Array Using Disk UUIDs

Aug 1, 2010

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.

I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).

These are the commands I used:


p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*


I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...

So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.

It's still trying to use /dev/disk/by-uuid/412d... to boot.

What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

Software :: Install GRUB In The MBR Of The Only Bootable Disk In The System, But Load Configuration And Images From Another Disk?

CentOS 5 :: Build A Bootable System Image On An Attached Hard Disk On A Running Machine?

Feb 27, 2011

I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer
to do a text-based install.

The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.

Debian Installation :: Non-system Disk Or Disk Error ?

Jan 22, 2011

After installation of debian, using the squeeze net-installer, on a HP elitebook 6930P, i get the following error. "non-system disk or disk error"

It is right after boot process, and just when it should load grub. Grub is installed in the MBR. Windows7, is installed as well, and is not an option to remove. (Should not be the problem though).

/ is set with the bootable flag.

The installation went without any issues, and I have actually tried to install twice with the exact same thing.

OpenSUSE Install :: No Disk Seen When Booting The Disk In Another System?

Jan 2, 2010

My dual proc, dual core Opteron MSI Master2FAR motherboard failed, and I try to boot a disk, used on this board as boot disk, on an Intel based Gigabyte GA-965-DS3. Both systems are x86_64 architecture.

The OS is on both systems is openSUSE 11.1.

On booting the disk on the Gigabyte, the disk is seen correctly by the BIOS, but not by the OS, and there is no /dev/sdX; no /dev/disk/... either. I am taken to a login shell from the ramdisk.

When I just mount this disk on the Gigabyte (booted with the Gigabyte's original boot disk) everything seems fine. No suprise to me, since the disk was fine, and was unmounted gracefully and physically taken off the MSI before the board failed.

I think that the cause lies in the fact that the harddisk controller on the Gigabyte is different from the MSI, and the driver for that controller is not available at boot time.

I have two questions:

- is my assumption correct, or is something else going on?

- if I am right, is there a way to get this disk booting on the Gigabyte (or on another system, for that matter)?

You might want to ask why I want to boot this disk on the Gigabyte in the first place, since I can mount it and see all data on it. I have a reason for that, but telling that story would make this topic too long, and it's too off-topic. Most certainly I will get to that in another topic.

It is an hp compaq d220 MT.It looks good and feels good, well at least for a while since it keeps crashing. The screen starts to flicker, goes black, and the only way to get it up and running again is to press the on/off button until the system powers off and restart.

Ubuntu :: System Unreponsive During Disk Activity (9.10)?

Mar 15, 2010

I have Karmic installed on three different computers (work, home and laptop), but on my home desktop there is a strange performance problem. During disk activity it sometimes becomes completely unresponsive. The mouse cursor doesn't even move. It actually seems fine when it first boots up, but it gradually gets worse as I use the computer for a while until it eventually becomes completely unusable. I'm only having trouble on the one system.The drive in the system is SATA, and I already checked to make sure DMA was on. It is a x86_64 kernel.I tried adding noapic to the kernel boot line after some googling, but it seemed to have no effect

Ubuntu :: System Becomes Almost Unusable During Disk Writes?

Apr 12, 2010

I'm using 9.10 Desktop 64bit on a Dell Latitude D830. I have 4 gigs of RAM and a 7200 rpm sata hard drive. Everything works pretty well, video, sound, and network. Flash isn't as smooth as in Windows but I assume that's a Flash/64bit thing and not necessarily an Ubuntu thing.

However, one area of performance still lags far behind my Windows XP experience, and that's disk writes. For instance, when I'm copying a large amount of information from a USB drive or from my Windows partition to my native partition, I can barely switch windows until the task is complete, nevermind trying to surf the Web. I thought that that might be related to the slow performance of the ntfs driver, but recently I have been doing a lot of work with VMWare, and I get the same result when trying to pause virtual machines - it writes a largish amount of information to disk in a short amount of time and I can't do much until it finishes.

Here are some things I looked at based on other threads to try to debug my issue:

~$ sudo hdparm /dev/sda
multcount = 8 (on)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)


That disk read speed is a little faster than average - several more tests showed it hovering around the 66 MB/sec range. Of the other info, I see that UDMA is on which I understand is good, but if there is something else there that I should fix I don't see it.

I know that my computer can handle these tasks (at least the vmware stuff) without such a significant interface slowdown because in XP I did it with less RAM than I have now. Is this just the way that the linux kernel scheduler fails to account for UI needs?

Ubuntu :: Disk Operations Freeze System

Jun 19, 2010

When I do some copying of files, or any background disk activity with file reading (transcoding a movie, uploading a big file to FTP, virus scanning) all computer becomes so slow, that I hardly can move my mouse, not to mention any productive use. I have SATA HDD, and Intel Quad CPU. I took measures to be sure it is not CPU or memory resource problem. Gentoo, Fedora, Windows don't freese that much on file reading. It is not a filesystem problem, or HDD, cuse I tried exactly this partition with other OSes.

Nice has a minor effect, but is is not enough, and I can't always start Nautilus with another nice level when I want to copy a file. What can I do to lower the priority of disk operations globally, and make apps to share disk thoughtput equally, not the one to occupie the disk until it finishes?

Ubuntu Installation :: Non-system Disk Error

Aug 9, 2010

I got a HP mini 5102 yesterday and decided that Win7 wasn't doing it for me so I would put ubuntu netbook remix (10.04) on it. Set up a usb stick with the installer (using universal usb creator) and booted from it.

I decided that I would do a full install of ubuntu as I have no need for windows on this machine, hence I left no partition for windows when doing the install. The install went fine but when the machine restarted I was faced with a black screen and the error message "Non-system disk error".

At first I thought that I had messed up the boot order and it was trying to do a network boot as I was getting "PXE-E61: Media Test Failure", so I changed the boot order and fixed that problem but am still getting the non-system disk error.

I figured that I would try and boot from the usb again and see if I could redo the install or just boot from it for the time being but when I tried that I got the non-system disk error again (though, this time if I hit any key when the error message is showing it quickly flashes "geom error" before going back to non-system disk).

Ubuntu :: Fail To Mount Disk Right After System Boots?

Apr 10, 2010

I got a little problem with Xubuntu here. Every time after I boot the system, I find one of my partitions from fstab not mounted where it's supposed to be. I do mount -a, and it replies: "mount: /dev/sdb6 already mounted or /mnt/data busy". Checking lsof of neither device nor mount point gives me nothing, and checking the output of mount I see device isn't mounted anywhere.

It gets better than this: after some time, device can be mounted just fine, this time is from 11 to 12 minutes. If something is doing anything with my device that takes whole 11 minutes, how come I don't know what it is? How can I mount device on boot? Some more (ir)relevant facts:

1. This partition is the biggest - 376 Gb

2. Here's my fstab line for this device:

3. After the installation, I changed the mount point in fstab, and using /dev/sdb6 instead of UUID is a result of blind experimentation
