Ubuntu :: 41GB Of Space Missing / Why Is So?
Sep 25, 2010
I've been using Ubuntu 10.04 since it came out and I was just wondering why 41GB of space is missing. You see, I did a complete repartition and reformat of my 320GB hard disk (already tried ext3 and ext4) and assigned 2GB for swap, 10GB for /, and 308GB for /home. Thing is, when I check the available disk space of, say, Videos or Documents (which, I understand, are contained in /home), only around 267GB of space is available. If I run the Disk Utility program it reports the capacities correctly (2GB, 10GB and 308GB). This didn't happen with Ubuntu 9.10. Where did my 41GB go and how can I get it back? I don't think it's accounted for by the differences in the way the OS counts bytes (powers of 2 or actual number of bytes), because 41GB is a big chunk of 308GB.

Normally, when ever I have an issue with ubuntu (which, for me, is often; I'm quite new), theres generally an error message to google, but such is not the case this time. So, I finally got my itouch to sync with gtkpod, but I accidentally messed up the process and didn't do the first sync properly, which meant the Firewire GUID wasn't properly set up, which then means every time I try to add music, it takes up space, but isn't recognized by the device. Well, I ended up find out and fixing the problem, but now my ipod has about 1g of music on it that is not recognized by my ipod, and thus, very hard to find and delete. Is there a way to get my space back, without formatting the itouch?

I recently copied about 14gb from my external hard drive to my Windows 7 partition on my hard drive (from Ubuntu) I know where I put it, but I turned my laptop on today, and I can't find the files from either operating system, but the space is still missing.

I have a dual boot machine, and I made the windows partition 13 GB on a 120 GB hard drive.I was testing out a program on the windows partition, and I deleted it and installed a different version, now I'm trying to install the first version I was using. The problem is that its now telling me there's not enough space on the hard drive.why does the program not remove everything when I try to uninstall?if I install a program and then remove it , I should and up with the same amount of free hard drive space shouldn't I?

I use vuze. I added some torrents to it, but some time after i removed them using vuze's interface. I did these steps:
1. Right button click
2. Remove and
3. Remove both
After doing this, there was no change in my free disk space and some bizare things started to happen. Here is a screenshot about free disk space confusion that is happening. The partition is ext3. Does anyone know what could be the cause of this? How can i fix this? Does anyone experienced the same problem?
Here is a screenshot showing differences in free space displayed by nautilus and df.

I started getting this warning that my Home partition disk space was running low, so I ran a disk space analyzer which only told me that I was using about 650 MB. Since I had 5 GB allocated to the home partition, I knew that something was not right. After manually going through all of the primary subdirectories on home, I found the culprit, namely an unexecuted game installation directory taking up about 4.5 GB. So I deleted the files, but then I didn't get my disk space back. I rebooted, no change. I ran this program called sfill, part of Secure Delete, which is supposed to wipe the directory 38 times and totally clean everything off. Still, no change. Any ideas how to reclaim my disk space?

On a fresh install my 320GB computer shows a 317GB 'File System' a 'Swap Capacity of 3.1GB and 'Free Space' 273.8GB !
The 317GB doesn't want to partition
How do I get access to the remaining 43GB ..less whatever elbow room Linux needs to utilise which is not 43 GB !

I recently decided to wanted to switch from windows to ubuntu 11.04 since linux can do the same work as windows for me. While going with a fresh installation of linux by itself I noticed that instead of my original laptop hdd space of 350gb it said allocated 320gb. I went with the install and now that it is ready the disk manager says I have 280gb space what is this please? Should I reinstall ubuntu to get the missing hd space ?

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!
Is it something to do with journaling?

just some time ago, my /usr partition's used space is started to increase rapidly, and currently it reached 17.5GB. We put /usr as a separate partition (/dev/sda2)
So when we do "df" this is the result:
Code:
#df
...
/dev/sda2 20315844 17612628 1654576 92% /usr
...
But what makes me puzzled is if I do "du", I only get 4.3GB instead of 20GB as "df" reported.
Code:
# du -csh /usr
4.3G /usr
4.3G total
So I'm missing approx 13GB here. My question is:where does my 13GB missing?

This is not a huge deal but I have missing hard drive space, I re-sized an iso with k9copy I then used mv to move it to the other iso like so:
Code: mv this.iso that.iso which moved and renamed it, however I did not get any drive space back by effectively "deleting" the first iso. So my question is do I have an unnamed iso file floating around that cannot be deleted?

My root partition seems to missing 1.6 GB of space. From "df -k" I get this output code...
I can't find any rootkits with rkhunter and chkrootkit, and fsck reports no errors.
Does anyone have any idea what might be going on here?

I was trying to install Ubuntu as a dual-boot on my Windows Vista laptop. The hard drive is 250 gb: Vista boot 157 gb partition; a partially-occupied 33 gb partition which was designated as swap-space; a newly partitioned and ext3 formatted 30gb for the Ubuntu installation. I believe there is also a hidden partition ~20 gb with "hidden" system info. During installation I received an error message concerning the swap space partition, which forced me out of the installation and back to the ubuntu partition manager screen. Now in Vista my 33 and 30 gb partitions are missing. Is there anyway I can get back to pre-Ubuntu state?

I seem to have a major discrepancy between what df reports and what du reports. df tells me that I am using 20G, but I am only able to find 9.5G using du. What follows are the ls -l of root, a df of my system, and the du for every directory in root that is not a symbolic link, mnt, or proc. I would appreciate any suggestions on where to look for the remaining 10.5G that seems to have disappeared.
I am running under VM Player code...

Purchased (4) 2TiB Drives (actual disk space) and created a RAID5 array expecting to have 6TB of useable disk space, however actual useable space is 5.46TiB.
So, the question is where did the disk space go?
First off, I can say for certainty the disks actual useable is verified at 2TB each have mounted and formated on a non-linux system (OSX).
Disks - 2TB Per disk, Tested HFS, Actual 2TB Useable
root@server:/server# fdisk -l 2>/dev/null | egrep "sd[hijk]" | grep Disk
Disk /dev/sdh: 2000.4 GB, 2000398934016 bytes
Disk /dev/sdj: 2000.4 GB, 2000398934016 bytes
Disk /dev/sdk: 2000.4 GB, 2000398934016 bytes

so I just installed Squeeze Alpha1 amd64, dual boot with MS Vista using Grub. Everything seemed fine, but I'm apparently missing about 40GB of space. It should be set up as so:
101GB NTFS /dev/sda1 - Vista
12GB NTFS /dev/sda2 - HP Recovery
45GB ext3 /dev/sda3 - / Debian squeeze
[code]...

Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
2. If system have only 256MB of memory (embedded system) and suppose Kernel Modules eat away all the memory during boot. User space will be left will no memory. Is this case possible?

I am developing a I2C CDROM client driver. The CDROM firmware supports TOC information read through a I2C command. It sends the TOC information in burst ( Interrupts a GPIO pin when it is ready ) and my CPU does a I2C read to read the TOC. When the CDROM firmware finishes sending the last data burst , it informs my CPU that it is done with the TOC, by a flag in the last data burst. I would like to know, which is the most efficinet way I can send these TOC information to userspace?

I wanna write a file in kernel space but from my searching I can to know that instead of writeing file in kernel space ,I can write data to user space by copy_to_user space.
But link is missing ...I dont know how will my user space will access kernel space means my function in kernel space which will do copy_to_user /....How my user space function will call my kernel level function ..
Can any one of you provide me with some example file which are doing this .I know every char driver is using it ...but i could not trace back how user level function is accessing it ...i m confused between user space and kernel space.

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 ... :'-(
In case you're curious, here's my /etc/fstab:

OS: RHEL AS 5 64-bit
HDD:300 GB Hardware mirror (HP blade bl460c)
While installing OS, in partition window after OS file system structure I've left 277 GB. But after installation it shows Size - 255GB and available disk space is 242 GB.
Isn't it weired? How can I use the total amount of space in Linux? I need the whole 277GB exactly. What should be my workaround?
