General :: Installation Utilities Split Root File System
Jan 21, 2011
standard Linux installation utilities split the root file-system and the home file-system on two separate but relatively equal-sized partitions? For example, when I put fedora on an 80GB disk, it automatically gave the root file-system 32GB and home 30GB and the swap 8GB of space. However, since my home file-system has a directory with 28GB of files in it, why is my root file-system reading 100% usage? Is the home FS overlaid on top of the root FS? Is there an advantage to doing this? I just made a boot partition (50mb or so), a root partition (90% of the disk space) and a swap (4%-5% disk space).
I recently installed ubuntu 9.10. I have been trying to launch utilities and other programs that have .exe extensions by double clicking the .exe file. Each time I attempt this I get the following error message in archive manager:
I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.
So I have an external hard drive (wd passport) that I want to install ubuntu on. I created 100gb partition via diskutility (fat32) and it seems I can't install ubuntu on this partition.
I would like to start off by saying this: I am very new to Linux, and this is my first time installing it, therefor I am having some very newb-like issues. Please bear with me.I am currently at step five of the installation process of Ubuntu, and I clicked on the partition which I have set aside to install Ubuntu onto, but when I proceed by hitting forward, I get the following error message:"No root file system is defined.Please correct this from the partitioning menu."My question to the community is, how would I correct that? How do I turn my 20GB partition into the root file system?P.S. I searched the forum for this issue, and being that it sounds so simple, yet I found nothing about it being previously asked, I feel sort of dumb....
When I tried to install 10.10 'side by side' with 10.04 and OpenArtist for triple booting I get the messageQuote:No root file system is defined. Please correct this from the partitioning menu.I don't have the screen in front of me now but what5 does it want me to do and how do I do it?
I'm having a problem and it seems like partitions during the dual boot install.
Here's EXACTLY what I get...
Menu: Allocate drive space Erase and use entire disk X Specify partitions manually (advanced) [X denotes I chose this option]
I have 3 partitions on my gateway laptop...
[graphical bar across the top] sda1 NTFS - 10g - weird partition w/recovery software or something from Vista sda2 NTFS - 140g - Windows Vista 47g FREE SPACE [this is where I want ubuntu]
[Code].....
I click "Install Now" and I get this error:
"No root file system is defined. Please correct this from the partitioning menu."
I am running a RAID0 array, with Windows 7 Ultimate x64 installed.
When i install LL10.04 through Wubi, it installs fine, reboots, continues the installation procedure, then it gives me an error box "No root file system is defined".
I have attempted pressing the "OK" button 10 or 15 times, however it does not progress. The box just keeps on popping up. My only option is a hard reset.
I've tried downloading the latest version of Wubi from the official website, and allowing Wubi to download ubuntu itself, and still nothing.
I do not want to create a new partition for Ubuntu and use the GRUB loader. I have a multi boot system and would like to stick to the windows boot loader.
I am pondering a reinstall of a freshly installed Ubuntu; I may or may not take that drastic step.However, I have partitioned my drive to include a 16-GB partition labelled "Ubuntu-tmp", in my case /dev/sda7, with the intent of mounting that file system as /tmp. Depending on how I decide to go about the reinstall I need an answer to these questions:If I reinstall: Is it possible to designate /dev/sda7 to mount as /tmp during the installation process?If I cannot designate the mounts at install time, or if I opt not to reinstall: I can't really empty the /tmp directory in the root in order to properly use it as a mount point for [the file system on] /dev/sda7; many files in there are still in use by running processes. So how can I clear the /-mounted /tmp directory and assign it to /dev/sda7?
I have attached a screen shot of gparted to illustrate my layout scheme.The gparted manual suggests I select the partition, click [Partition]->[Mount]. Of course, my gparted drops a menu with [Mount] is absent and an [Unmount] option is greyed out.This raises a question of how I am going to mount /users and /var in their intended file systems (/dev/sda8 and /dev/sda9, respectively), because the [partition] menu looks the same for these partitions as well.
I was trying to install Ubuntu desktop and laptop edition on a Sony Vaio netbook from a USB drive, but after I select the entire disk to be used and hit enter I get this message No root file system is defined. correct this from the partitioning menu. If I try to start windows I just get s black screen.
When I get to installation step "Allocate drive space" I get this message, "No root file system is defined. correct this from the partitioning menu." What is the source of this error and what do I need to do to correct it? I don't see a partition menu other than a choice of using the whole drive or a partition? Below are the choices that I have made. Specify partitions manually (advanced) Allocate drive space Choice are device (/dev/sda4) Type ((ext3) size) Mount Point (no choices offered) Size (42088 mb) used (670 mb) boot looder is sda Windows 7 ext3 42088 MB I am installing Ubuntu 10.1 on a seperate partition. Windows 7 is on another partition. The machine is an ASUS A52F Laptop
i have one partition of 45 Gb...and other of 250 Gb in which windows 7 has been installed..i booted from ubuntu 10.10 CD and then i chose the installation option on desktop...but when i selected the partition of 45GB for installation..the error message said that "there is no root file system on the drive, set it from partition options"..
I've been trying to install ubuntu 11.04 64 bit on a partition next o windows 7 64 bit.When I use the default option (no matter how large I make the partition) I get the error message that not enough space could be created. I read this could e solved by defragmenting the hard drive which I did, but the problem persists.I next tried to partition manually but go the error message that there was "No root file system is de or something similar
I am getting an error while booting my linux system: Can't mount root file system.Boot has failed, sleeping forever.OS is Red hat enterprise linux 6, With Intel P4, 1 GB Ram, 120 GB IDE hdd seagate. it was working fine from last 4 days. from today morning this is giving error. only mysql & apache is installed in it. please suggest is there any way to repair the root & boot volumes. waiting for valuable reply.
Is it possible to encrypt the Entire root file system using LUKS.I am currently using Ubuntu 10.4 LUCID.After several hours of Google ,most of the articles were focusing to "Encrypting a drive/removable media ".. My aim is to encrypt whole File system which is currently using.
My Concerns, How to Encrypt a running file system? Will it lead to data loss?
im trying to prepare my partitions for fresh installation. The partition manager didnt list anything with an error message that said:Quote:No root file system is defined. Please correct this from the partitioning menu?This is what Gparted displays Quote:
I'm a long time user of Debian, but I'm having trouble with my partitioning process. Here is where I currently stand:
I am installing the latest Wheezy build. I am trying to install debian with an encrypted LVM that spans two hard disks.
My partitioning layout is as:
1. /home 2. /root 3. swap 4. /boot
I then added partitions 1, 2 and 3 to a physical volume group. I then took that physical volume group and added it to a logical volume. Then I encrypted the logical volume, leaving the /boot partition untouched. I was under the assumption that the only partition the system needed free to reach the loading of the LVM is the /boot partition, as it holds the files necessary for booting. But when I attempt to finalize the disk, it gives an error stating, "No root file system detected". That would be an issue as it is currently sitting inside the encrypted LV. Am I wrong in including the root partition in the encrypted LV?
What is the best way of having as little of my file system non-encrypted as possible while still allowing a proper boot?
I recently recieved Ubuntu 9.04 Desktop Edition CD-ROM through snail-mail after requesting a copy online and I want to install it on my laptop, although I wish to keep Vista which is on it now.
My laptop has a 250GB hard drive. Although when in Vista this is represented as two separate drives each of 110GB, (C or ACER and (D or DATA.
Using the CD, I start the installation and everything is straightforward and self explanatory, until I get stuck at step 4...
Where I am told by the ubuntu installer: "This computer has several operating systems on it." (I'm confused now, I thought it had one, Vista.)
Beneath I am shown a bar representing my disk space which is divided between...
I am given the option to use the entire disk: 'SCSI1 (0,0,0)(sda) - 250.1GB ATA WDC WD2500BEVT - 2', (and from the mention of 250BG in the name I'm assuming this is one disk and not the two separate drives named C: & D: in Vista.) ...along with a warning - "This will delete Windows Vista (loader), Windows Vista (loader), Microsoft Windows XP Embedded and install Ubuntu 9.04". (The aforementioned "several operating systems" obviously.)
But I wish to keep Vista, so I select the option to "specify partitions manually" and am brought to a screen named 'Prepare Partitions', where there is a table somewhat like this:
I am then given the option for "New partition table", and if I select any of the bottom four devices I can 'edit partition' or 'delete partition'.
Selecting the device /dev/sda3 (because it is the one that I'm guessing has no operating system data on it, judging by the previous screen) and choosing 'edit partition', allows me the following options...to create a new partition size, to select what I want to use the partition as. (There are also two options for formating a partition, which is a checkbox, and Mount point. These are both greyed out.)
When I look at the 'Use as:' option, within 'edit partition', the drop down box allows me to use the partition in the following ways: - do not use the partition - swap area - NTFS - FAT 32 file system - FAT16 file system - XFS journaling file system - ReiserFS journaling file system - Ext2 file system - Ext4 journaling file system - Ext3 journaling file system
I am getting an error message at step 5 of 8 in the installation process. I am using Ubuntu LiveCD. The caption of the error is 'No root file system' and the message itself says 'No root file system is defined.Please correct this from the partitioning menu.' I enclose a screenshot of this. I had also problems with booting Ubuntu and Windows after installing Ubuntu to an external hard disk so I probably have to also create a new boot menu (may be it is differently called, 'grub' possibly, I am not really sure).
if this is an error that has already been solved, but I am running Windows 7, and when I finish installing Wubi in Windows, it asks me to reboot. I select Ubuntu and it gives me the error: "No root file system is defined. Please correct this list from the partition menu." I can't get past this error.
Information on the net seems very sparse or outdated for how to go about booting to a RAM disk. I need to be be able to boot a PC without a hard drive in it. I want to be able to PXE boot a PC and supply it with a RAM disk image that also contains the contents of the root file system (obviously stripped down enough to keep the file size small and the boot up time fast).What I have gathered so far is that I need to extract the contents of the initrd.img file, add files as necessary, and repackage the initrd.img file. What I get confused on is how to configure the kernel line parameters to tell it to boot to RAM and not the hard drive and how to go about modifying the init script in the initrd.img to not switch to the hard drive for the root file system. I can't find anything on the net that describes concrete steps on how to go about accomplishing all of this. I'm aware of the existence of Live CD's, but I need to be able to boot the PC without relying on a hard drive, CD, or any other external media. It needs to get all of its contents from the PXE boot server and boot to RAM only. I have the PXE boot side configured successfully. Also, putting the root file system on a NFS share is also out of the question.
I've been using *Unix systems for many years now, and I've always been led to believe that its best to partition certain dirs into separate FileSystems, off the main root FS.
For instance, /tmp /var /usr etc
Leaving as little as possible on the main / system.
Its so that you don't fill up the root system be accident, by some user putting in too bigger files in /tmp, for example.
I would presume that filling the / system would not be too good for Linux, as it would not be able to write logs and possibly other things that it needs to.
I believe that if root gets full, then there is something like a 5% amount saved for just 'root' to write to, so that it can do its stuff.
However, eventually, / will become full, and writes will fail.
On top of this, certain scripting tools, such as awk, use the /tmp/ system to store temp files in, and awk wont be able to write to /tmp/ as its full, so awk will fail.
However, I'm being advised that there is no need to put /tmp /var etc onto separate FSs, as there is no problem nowerdays with / filling up. So, /tmp /var /usr are all on the root FS.
I'm talking about large systems, with TBs of data (which is on a separate FS), and with a user populations of around 800-1000 users, and 24/7 system access.
I have a Rad Hat 7.0 old Linux system that crashed due to power failure. On reboot the system goes to Checking Root File System and does 92.5% check and fails.
Here are the error messages I get.
I don't know what to do at this point so I say yes and it goes in some wierd mode.
SO I ran fsck manually but I get an error PARALLEIZING FSCK.
I can't fix the corrupted stuff for the system to reboot. THIS IS VITAL.
From windows 7 i select to install on same windows7 partition after installation i select ubuntu and it start up to complete the installation put i get a message: "No root file system please correct this from the partitiong"
I reinstall again on a vartual machine with windows 7 it worked ok;
I installed it with other pc with windows xp it worked ok
I installed on another labtop the same problem occured.
