Ubuntu :: Volume Filesystem Root Has Only 25mb Space Remaining
Feb 28, 2011
I'm getting an error message that something along the lines of "volume "filesystem root" has only 25mb space remaining". How do I increase the volume size so I never have to worry about it again? This is the 3rd time I've tried ubuntu and it's sticking more and more but this has me thoroughly perplexed. I've got a 320GB HDD partitioned 3 times with a Linux partition being 7GB.
extend the size of a LVM2 volume group over the remaining free space available on a physical volume. My linux box is a Ubuntu Karmic 9.10 64bit, the 60GB hard disk has 2 win partition for about 19GB, a 1.5GB ext3 boot partition and finally a 36GB LVM partition (/dev/sda4) on which I created a volume group (volgrp) smaller 10GB than the 36GB physical volume (/dev/sda4). What I want now is to extend the size of volume group up to the end of physical volume. I tried to use the "vgextend volgrp /dev/sda4" but system answers me with following output:
me@pc:~> sudo vgextend volgrp /dev/sda4 Physical volume '/dev/sda4' is already in volume group 'volgrp' Unable to add physical volume '/dev/sda4' to volume group 'volgrp'.
My computer: (Lenovo T61 Thinkpad, running fc11 for about 2 and half months). Apparently I when I made my partitions I didn't leave quite enough room in my root directory, because I just completely ran out. Here is how my hard drive is partitioned:
The root had about 15 gigs on it, which just filled up. When I restarted to see if that would help, when it rebooted it went fine up to the log-in screen. Instead of the usual fedora blue background, it was black except for the log-in window, which looked very low-res. A little pop-up kept coming up saying the GNOME power configuration settings failed to load or something. When I logged in, the whole screen was black except for the mouse, and I could get no response. I have plenty of space left in home, so I rebooted to rescue mode using the first fedora installation disk, and tried the following command:
Code:
lvreduce -L90G /dev/mapper/DRIVE
which only returned:
Code:
lvreduce: relocation error: lvreduce: symbol dm_tree_node_size_changed, version Base not defined in file libdevmapper.so.1.02 So I couldn't reduce the size of home, and thus couldn't increase the size of root.
IN SUMMARY:
a) the lack of memory in root the probable cause for my computer not working
b) there a good way to reduce home and increase root while running this live disk
Note: When I am looking at it now in the logical volume manager, it says that on the whole physical volume there is only 400MB free. However, when I last looked (about 30 mins before I started having problems) it said there were about 100 Gb free.
Edit: Nevermind. I did some more research and it turned out to be more of a gnome power manager thing rather than a memory space thing, although I'm certainly going to increase my root memory now.
I have 160gb laptop. i installed vista in c primary partition which is 25gb and installed ubuntu in d primary partition which is 20gb. A remainig for my data. Now i tried to install CENT OS by formatting ubuntu. I inserted CENT OS DVD and restarted and i selected to delete my /dev/sda2 which is showing 20480mb and it shown me free space. but i tried to add partion /boot of 100mb it got added. but, when i am trying to add / of 3000mb in the remaining 20380mb free space it showing an error message that no free space is available.
My Lpatop has a 300G hard drive. It came, as many do pre-installed with a Window OS, in this case Vista 32-bit Home Prem. I had partitioned the hard drive to give a C drive of 97.7GB (Partition 2 /dev/sda 2/Host), a partition for applications and programs, D of 48.8GB (Partition 3 /dev/sda3) and a third partition, E for Documents, etc. of 148GB (Partition 5 /dev/sda 5 media/doc), which on scanning seems to be a sub set of a partition Partition 4 W95 Ext d LBA dev/sda 4.......There is another partition, Partition 1 /dev/sda1 and is called WinRE and is of 2.80GB.All are NTFS except for the Partition 4Windows works fine and I have no problems, but when I use Ubuntu I get errors on startup. In the first instance it will not install the latest Kernal and it gives a Battery Management error in GNOME. I get Storage warning messages all the time, which I believe is the cause of the problems. See enclosed.
I am assuming that the disk space issue is in Host and or Home. Other than all the operational data and applications I do NOT use the Ubuntu filing system, rather the Partition 5 which I created solely for this purpose, so it's not a case of deleting files, it is purely how Ubuntu created itself on install and its operational requirements.The problem is resulting in no space or ability to do updates and new installs, and Kernal and Gnome issues.
I installed Linux Mint 9 LTS onto the family computer last weekend, everything went okay apart from today when suddenly it displays a low disk space message.
The machine has a 250Gb HDD, and has the base install of Mint, plus Dropbox and Google Chrome. (Dropbox has about 500Mb in it). That's it.
The disk usage analyzer tells me that /home is 100% full, yet when I look into each dropdown there is barely enough to make 2Gb of usage. (The most being Dropbox).
I'm currently studying for my Linux+ test and I'm getting conflicting information regarding the rm -rf command. Yes, I know this a dangerous command, but my question is in regard to how the command functions. In one book I'm studying it says that rm -rf / home/myfolder (there's a space in there) will delete the entire root directory because there is a space between the root and home directory. It says that if there is a spacing such as this, it will ignore anything after the space, so in this case, it would delete the root directory and stop, not that there would be anything left anyway. Then in another book I have, it says that if you did a rm -rf folderName / (with the intention of adding the trailing slash to indicate it is a directory and not a folder) it will delete everything in folderName (assuming it's a child directory of your pwd) and then CONTINUE on and delete the root directory. Now, those two statements contradict each other. When you remove a directory, does the command line ignore anything after a space or not?
Transmission used to show space remaining on the drive you choose in the add window. Now it doesn't. Was this removed? I LOVED that convenience of not having to go to a separate file browser or terminal to show space. I tried posting at Transmissions forums but it's been 4 days with only 7 views and no reason to bump b/c the forum is so slow I'm still on the front page.
I recently cleared out some old partitions, and "/" was getting full so I made it bigger. It went from about 2Gb to 7Gb.
Now when I boot into my OS I get a dialogue saying:
Code: The volume "Filesystem root" has only 0 bytes disk space remaining
You can free up disk space by removing unused programs or files, or by moving files to another disk or partition I don't see how this is possible. If anything it should have more free space than it had before. how I might go about diagnosing this issue?
I installed Ubuntu using Wubi in my PC. Now my PC always warns me that "The computer has only 46 MB disk space remaining." My PC has 160 GB of memory and I have used a total of 50 GB so far. Thus, I should have 110 GB of disk space remaining in my hard disk.
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
This morning, my hard drive looked something like this - Windows Vista on a partition of around 100 GB (NTFS), Ubuntu 10.04 (ext3)on a partition of around 80 GB, 4 GB swap and a partition of around 40 GB (NTFS) containing videos and music and stuff like that. I wanted to resize the Ubuntu partition to around 30 - 40 GB and add the remaining space to the 40 GB partition.
I successfully reduced the Ubuntu partition using the Partition Manager app that comes with Ubuntu, but I was unable to add that to the NTFS partition. After a merge failed, I was no longer able to access the 40 GB partition. I tried restoring that with testdisk, and now I can't access anything! GRUB fails to load, and when running from the live CD of 9.04 (only version I had on CD) my Ubuntu partition and 40 GB data partition no longer shows up. I have over a 100 GB of free space instead.
I'll be extremely grateful For the record, I had an external drive plugged in while running testdisk.
so i have f12 installed on my hd with lvm using the whole extent of the HD , i want to reduce it so i can dual boot it with a windows system, i managed to reduce the logical volume to free some space, but i cant seem to reduce the physical volume, is this possible and how ?
Today I was installing a lot of software since I'm just setting up my Slackware system again after a fresh install, and I realized that my root partition has very little space left.
Here is the output of df -h:
Code:
As you can see, I have a 20G (19G here for some reason) root partition, 8G /var, and 86G of /home. I thought this would be plenty since many recent recommendations for / are 10-15G. Now, though, 17G are used up for some reason! How is this possible? I thought a full slackware install only had about 4G of software! I don't have any music or movies or any crazy huge files that I know of, and those would be in my /home directory anyway. Is there any way I can see which files are taking up all this space?
If it's necessary to allocate more space to my / partition, is it still possible to boot up a GParted live Cd, shrink /home a bit, move some partitions to the right, and expand my root partition? I would REALLY prefer I don't have to reinstall since I just spent a ton of time setting up my system again, but if worst comes to worst ... :'-(
My linux distro is CentOS 5.3. Today I edited /etc/sysconfig/readonly-root and set "READONLY" to yes, now my /etc/sysconfig/readonly-root file is like this:
# Set to 'yes' to mount the system filesystems read-only. READONLY=yes # Set to 'yes' to mount various temporary state as either tmpfs
I was happily browsing my new Linux Ubuntu Distribution, and a warning message popped up stating that there's about 145 megs in FIle System. how to solve this problem other than removing files?
So I transfered a few folders with videos in them to the public folder on an Ubuntu 10.04 laptop I have from my Ubuntu 10.04 64bit laptop. When I wanted to delete the folder I didn't have permission so I ran "gksudo nautilus" so I could delete it as root. So I deleted the folder but I did not get the space back!
I went to /.local/Shared/Trash and one of the folders I deleted was there but deleting it didn't get that space back either.
I did some searching but most of what I find doesn't help or tells me to look in the folder /.local/Shared/Trash folder but that didn't help any.
I have installed debian recently and not able to mount any other volume except FileSystem. It says -You are not privileged to mount this volume.I have tried everything including raising the permissions of the user and changing the group to root but in vain.??
I'm looking for insite on how it might be possible to grow an existingvolume/partition/filesystem while it's in active use, and without having to add additional luns/partitions to do it.For example the best way I can find to do itcurrently, and am using this in production, is you have a system using LVM managing a connected LUN (iSCSI/FC/etc), with a single partition/filesystem residing on it.To grow this filesystem (while it's active) you have to add a new LUN to the existing volume group, and then expand the filesystem. To date I have not found a way to expand a filesystem that is hosted by a single LUN.
For system context, I'm running a 150 TB SAN that has over 300 spindles, to which about 50 servers are connected. It is an equal mix of Linux, Windows, and VMware hosts connected via both FC & iSCSI... With both Windows & VMware, the aforementioned task of expanding a single LUN and having the filesystem expanded is barely a 1 minute operation that "Just Works".If you can find me a sweet way to seamlessly expand a LUN and have a Linuxfilesystem expanded (without reboot/unmount/etc)I have cycles to test out any suggested methods/techniques, and am more than happy to report the results for anyone else interested. I think this is a subject that many people would like to find that magic method to make all our lives much easier
I am dual booting Ubuntu and Windows 7, I have just shrunk my windows partition and would like to add that extra space to the file system partition. I installed Gparted but it told me I need to unmount the file system partition manually. I would like specific instructions on how to do this,
I have created two logic disks /dev/VolGroup00/LogVol00 and /dev/VolGroup02/LogVol02 After reboot has disappeared /dev/VolGroup02/LogVol02 How to restore logic volume?
I have a 6x1TB RAID5 set up for testing on ubuntu created with mdadm and formatted with an ext4 fs.
This is being shared over CIFS for windows clients. When looking at the fs from both the file box and the clients, it says 4.47TiB total capacity, and 4.24TiB free space. The only folder is Lost+Found which is empty.
I don't have much experience in Linux filesystems as of yet and I don't understand where this 300 gigs has gone!
The root partition on my server seems to be full. I'd like to find out what files are on that partition and only that partition so I can free up some space on it.
Ubuntu 10.04.1 I was just tidying up my panel when I notice the Volume icon is taking up the space of two icons: I can right-click and Move it to the left or right
HPDL385 with dual raid controllers (8 disks each). During the install of the ISO, it sees the raid controllers individually. I tried "One Generic Drive" but it still only partitions one of the raid controllers.Is it possible after the OS is installed to configure the space as one logical volume?
Given the name of a mounted volume (e.g., /mnt/vol), how would I determine its capacity and available space in C? I've been googling for a while now and nothing jumps out as the solution. I can use getmntent() to get the name of the actual partition that is associated with the mount point, e.g. /dev/sda2, but I can't figure out how to find the capacity of the volume nor how much space is remaining, such as what the df command shows. Is there an ioctl defined to get this information or some other system call?
I am not sure whether this is something that can be answered here, but I figured this is the best place to start (next to google not giving me the answer I was looking for). One of our clients are running HPUX as filesystem, however when the support guys need to report the filesystem space they keep getting it wrong. Even after someone gave them the full command which will do the calculations for them, they still seem to make mistakes. On linux the df -h works very weel but this is obviously not available here...can use to display the filesystem space in the correct formats? Even if there is a set of commands that we can work into a script and they can then just run the script.
I'm running CentOS 5.2,on a 64-bit x86_64 Linux machine with kernel version 2.6.18-128.el5 smp. I appear to have version 2.9.4 of xfsprogs. I have a 22TB xfs filesystem ,Yesterday, the hard disk is full, today released a 7.7T disk space.But still can not write to new file. software ambience:
