Ubuntu Installation :: Cannot Make Enough Space / No Root File System?
Jun 27, 2011
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 currently have a server with the default VolGroup00 that contains logical volumes for the root file system and swap using logical volumes LogVol00 (root) and LogVol01 (swap.) I need to take space from LogVol00 and move it to LogVol01. I have found documentation for increasing the swap, and the resizing the logical volumes. However in the documentation and the man pages it says that I have to reduce the size of teh file system on the logical volume I am going to shrink. I have found documentation resizing the logical volumes but not the file systems.
I am attempting to PXE boot Redhat 5.4 and load the OS into RAM. Here is how far I have gotten so far:
I have successfully configured my DHCP, TFTP, and PXE servers. The PC that is booting up Redhat 5.4 is able to get a DHCP IP address from the server, grab the kernel and initrd from the TFTP server, and boot up from there. I have this setup working if I store the root file system on a NFS share on the server and use the kernel's NFSROOT parameter. Long story short, I now need to get this same setup working without using NFS if possible. I have spent several hours google searching how to create a RAM disk (initrd) that also contains the root file system. I must be searching the wrong keywords. Anyway, based on what I have read so far, I need to do the following:
1. I need to pass different kernel parameters. It needs to look something like:
2. It seems like newer versions of initrd are created using the cpio tool. So would this simply be a matter of booting to my hard drive that has Redhat 5.4 loaded on it and running:
To create the RAM disk with a root file system attached to it? I have a feeling it has to be more complicated than that but I just cannot find any sites that specifically explain what would be involved with creating an initrd file that can also be used as the root file system.
3. Would I need to modify the init script (many sites call it "linuxrc") at all in order to accomplish what I want to do? For example, I found this site:[url]
My understanding of this page is that you have to create a linuxrc script that basically does the work of decompressing the file system into /dev/ram0 and mounting it to /root. Is something like this actually needed?
4. The kernel must have certain parameters set such as enabling RAM disk support.
I have most of this setup working. I just need to figure out how to basically store the contents of the OS on the TFTP server and then tell the kernel to load that OS into memory. Based on what I have read, this should be possible (otherwise, how do Live CD's work?).
I am interested in making the root file system is read-only. I've moved /var and /tmp file systems to another partitions. There are two files in the /etc directory that need to be writable.
These are:
I've moved this files to /var and linked it. I've added command to the /etc/rc.d/rc.local file:
That's it. Are there other solutions to make the root file system is read-only?
Running Squeeze here. I added a new SSD to my system. Root is /dev/sda3 and I want to clone that system to the new SSD on /dev/sdb1 and make it bootable. I tried:
mount /dev/sdb1 /mnt/ssd_root cp -dpRx / /mnt/ssd_root
but to no avail. I cannot get the new system to be bootable and available through Grub. Part of the problem is that I do not know my way around Grub v2 so well, I could probably manage quite well with legacy grub. So, whats the easiest way to clone a system and make it bootable on another partition? Should I be using debootstrap, and importing/exporting the package list to install the same packages on the new system as the old? or is using cp -dpRx to copy the old ok? How do I make the new system boot?
i just installed ubuntu 9.10 onto my windows vista laptop. i ran ubuntu update manager but it tells me i'm low on disk space. system monitor tells me that i still have 50.2 GB of space but the problem is that i only have 68 MB left in my / File System. how can i increase disk space in / File System?
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 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.
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).
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.
In System Monitor, on the File Systems tab, the "Total", "Available" and "Used" columns don't seem to add up, and the "Used" percentage doesn't seem correct either.
My config: /dev/sda1 = 80 GB SSD drive, / partition. /dev/sdb1 = 50 GB FAT32 partition of an external 500 GB USB hard disk. /dev/sdb2 = remainder of the 500 GB USB hard disk encrypted using luks.
Screenshot: The /dev/sda1 figures don't really add up well, but they're close at least (how you get "50% Used" from any of those figures I don't know!).
However, for /dev/sdb2, they're miles off: "Free" = 146.2 GiB "Total" = 409.7 GiB "Available" = 125.4 GiB "Used" = 263.5 GiB
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 would like to upgrade my ubuntu to 10.04. My root partition has only 1GB free but I have plenty space in my home partition. The last time I upgraded I expanded my root partition for the upgrading, but I am not really happy with this solution. I would like to create a link from the directory where the installation files are downloaded to another place in my home partition. I don't know where are downloaded. It is sufficient with a symbolic link? Must I mount a partition or a usb memory?
I am trying to install Ubuntu on my laptop and it works fine running from USB but during the install from WUBI I get the error "no root file system is defined". I have followed several other threads where they got the same error but my results do not appear to be the same as theirs in the analyzer script.
I've been using Ubuntu 11.04 from my USB-stick for about 2 weeks now and I really enjoy the OS. So I ran Wubi in windows a couple of times resulting with the same problem after rebooting and showing a error "no root file system is defined" during the finishing stage of the installation.
I did the bootinfoscript and it shows that mounting failed.
Code: Boot Info Script 0.60 from 17 May 2011 ============================= Boot Info Summary: =============================== => Syslinux MBR (4.04 and higher) is installed in the MBR of /dev/sda.
I have installed ubuntu onto a 64 bit Windows 7 machine using Wubi. [Note: I thought that I was downloading 10.10, but the installer said it was 10.04] When Wubi gave be a choice of which drive to install on, I choose my second drive (B) My Windows 7 resides on (C)
The install seemed to take a long time, but I think that was because it was downloading the whole operating system install files. When it was finished downloading it asked me if I wanted to reboot, I selected yes (reboot). Then the boot screen gave me the choice: Windows or Ubuntu. I choose Ubuntu and then I get the error:
"No root File system is defined. correct this from the partitioning menu."
Damn that Ubuntu splash screen was so beautiful and I thought I was home free. I have read a few threads here and other places on line. I have read that I may have to partition the drive. Was my mistake in choosing the B: instead of the C: drive? If I partition can I partition from inside windows using the computer management software it provides? Do I need to partition at all? Or can I just move the installed files to the C: Are the files movable? In the ubuntu directory I see a file: uninstall-wubi.exe. Should I use this and try a reinstall onto the C:
