General :: Disk Size Mismatch Using Df
Feb 21, 2011
When I run df command, the sum of free and used space doesn't tally up to total space. Now I found an explanation in this thread: URL...The amount of "reserved" space seems a little too high as OP of the thread had commented, but may be that's what needed. Now my question is is there a way to change/specify this amount of "reserved" space manually?Also is there a way where you can see the actual disk usage for every mounted partition including the hidden "reserved" space? Because sometimes this mismatch makes the output of df very confusing!
I am attaching output of df, and fdisk from my NFS server. The amount of reserved space seems to be close to 5% of the total partition size.

I have Ubuntu 10.10 installed and a few weeks ago I tried upgrading to 11.04 using "Update Manager" BUT I got the following error after a few hours of fetching all the files from internet except for one
Code:Could not download the upgrades
The upgrade has aborted. Please check your Internet connection or installation media and try again. All files downloaded so far are kept.
Failed to fetch [URL]
I thought there's something wrong with the internet connection in spite of that everything else works well.. I tried upgrading in different times in different days, I redid the process again today and I got the same error again. Is there any other way to upgrade or ignore this package?

When I try to update my software through update manager, I get this error:
W: Failed to fetch [URL] Size mismatch
As a side note, when I enter Update Manager, it does not show 10.10 as an available update. I have checked my settings. I am quite kurfluddled by all of this.

this is at the root of the problems I'm about to describe: Whenever I try to upgrade my Debian installation, I have repeated "size mismatch" errors that necessitate restarting the upgrade process. Since I'm using Debian Squeeze there are lots of upgrades to be done every week. Today, for instance, because I've not upgraded for a few weeks I have to download over 300MB of files to complete the upgrade. However, because of the size mismatch problem this download may well turn into something between 1GB and 2GB, as I repeatedly have to re-download files that were successfully downloaded in the last failed upgrade. What with my ISP limiting me to 7GB per month, I'm finding that merely keeping Debian up to date is using up most of my allotted bandwidth.
I've tried setting the Aptitude preferences not to "remove unused packages automatically", and not to "remove obsolete package files after downloading package lists", but for some reason I still find that files I downloaded in the last failed upgrade have to be downloaded again (and again, ...) whether anyone either knows how to avoid the package size mismatch problem (I can't change my ISP, which has a monopoly on providing internet to my area), or alternatively knows how to set Aptitude not to forget the packages it has downloaded successfully during each failed upgrade, thereby allowing me to avoid such a huge bandwidth usage on my frequent upgrades.

sudo apt-get install ubuntu-desktop fails and has been failing for the last two days, I installed both the lto and the 10.10 newest, starts out OK and runs for about 5 minutes then finishes with many 'failed to fetch [URL] size mismatch issues. This is the first one after many installs over the last two years. Is there something going on with the US servers? On closer examination of running sudo apt-get update it seems to be fine till it hits the pool directory on the server, lucid main and lucid-updates are fine, breaks when it goes past those.

a client brought in an 160GB external HDD and wanted to get the files off it, there appeared to be no partitions on the disk but i thought it may have been formatted to use the whole disk. I tried to mount it as the various FS types the client thought it may have been to no avail.
I ran testdisk on it which told me that it previously had a mac partition table and a 210GB partition on it (which is larger than the disk) could anyone enlighten me as to whether or not this is even possible, and if so how could i retrieve the data?

I use dd in its simplest form to clone a hard drive dd if=INPUT of=OUTPUT However, I read in the manpage that dd knows a blocksize parameter. I was wondering whether there is an optimal value for the blocksize parameter that will speed up the cloning procedure?

I'm new to Fedora 14, vmware player. After getting Fedora up and running in VMware player. The disk size was 2.7 GB. After three hours of working with it, the disk size has bloated to 4.3 GB. I havent added software to account for the near doubling in size. How do I reduce the size back to 2.7GB range or lower. Im new to Fedora and superuser controls. Im removing more software than adding software. Is this a VMWARE problem or Fedora problem?

I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: The database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. DMA: Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it.
Write-caching: When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it.
I have been looking for information on how to ensure these are so for CentOS and Ubuntu, but can't seem to find anything at all. I want to be able to check these things and change them if needed. The actual hardware involved is very modest. The point is to get the most out of what hardware we do have, even though it's "not very serious hardware" from a broader perspective.

I created a VM disk image with kvm-img, but I forget what was the max size of that disk image when I created it. Currently, its size is 6.2G, I want to install some large packages in that VM, so I want to make sure the disk image can expand to an adequate size.

I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive. When mounting from file browser:
Code:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda,missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so The end of dmesg said the following:
Code:
dmesg | tail
[ 82.130904] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)
my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:
Code:
# sudo e2fsck /dev/sda
e2fsck 1.41.14 (22-Dec-2010)
The filesystem size (according to the superblock) is 122096646 blocks
The physical size of the device is 122096381 blocks
[code]....
this is as far as I've gotten. This drive holds over a decade's worth of work for me and is extremely valuable. I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. What is it that I need to do to restore my drive to working status?

after installing thunderbird my computer was unable to load linux (fedora 13) while loading it reaches the blue screen with logo and halts. it didnt respond to any button. then i went to a single user by Ctrl+Alt+F1 because im a total newbie and thinking that video driver is missing, i installed nvidia using yum! but the problem remains. now entering startx gives:
API mismatch: the nvidia kernel module has version 195.36.24, but this nvidia driver component has version 260.19.12. there is always this error: no display specified/etc/X11/xorg.cof file has Driver "nvidia" in the Section "Device", but it is supposed to be "nv", because it was so previously. manually editing this doesnt help.
1). is it possible to "unyum" what i did and get back the driver i used to have? 2). how can i get the display working? 3). were there any known to you cases when thunderbird could mess up display drivers?

I have a server and a few clients set up with LDAP and NFS. All user files and logins are on the server, and I can login as a normal user on any client and get to my files. However, if I log in as root on a client, I can't write in root-owned directories on the NFS. I suppose that client-root and server-root are different.
Question: is there some way to convince the LDAP or that client-root and server-root are the same?

I am trying to compile and install a new kernel. I have downloaded the 2.6.37 version from kernel.org and I have extracted it in usr/src/linux-2.6.37/ folder.I have tried to compile it and install it according to the instruction given in the following web site and which I found very useful:ttp://www.digitalhermit.com/linux/K...WTO.html#INTRONevertheless, I am encountering some problems during the make install modules process as I get some warnings (i.e. The title of this post).I thought to ignore the warnings and continue by copying the modules in /lib/modules/linux-2.6.37 but this is not possible since at that directory there is no folder created with the new kernel I am trying to install and thus I get a msg saying: FATAL: could not load /lib/modules/2.6.37/modules.dep.
The warning message: WARNING: modpost: found X section mismatch(es) suggests to run a make CONFIG_DEBUG_SECTION_MISMATCH=y.At the moment I am running a make again and saving the output to a file so that I can see later on what are the mismatches that I get. In any case we are talking about more than 50 mismatches so I am wondering if these mismatches are not that serious and the problem I cannot install and copy the modules is something else

On F12 and sure need to upgrade. Way back when I first had a bad disk on the "system" disk that was 80G, I only had a 200G lying around. Next time that happened my other 200G wasn't "big" enough it said, so I put a 500G in there. Now it seems I got more bad blocks etc but I need to lower the size 'cos I don't want to put a 1Tb HDD in there. My question from all of this is, how do I decrease the image so I can put it all on a smaller HDD?
Used space on the system disk's partitions is about 30G, so an 80G disk should be sufficient. What I can think of is that I need to "move" all data to the "beginning" of the HDD, then make an image of it but and the entire disk, just the data. I've tried that with no luck since the image seem to get as big as the HDD, hence why I always needed to increase the HDD all the time.

Is there any other way to check the overall size of the hard disk other than just fdisk -l? This is because the cloud server that my company has purchased is supposed to have 50GB of hard disk size,It shows that it has two SCSI drives, only both summing up to 50GBs. So what is the second SCSI drive, and why is it divided that way? dev/sda and dev/sdb???

I am trying to figure out the "actual" disk size used by my system. When I run the "df -h" command,I am not taking here into consideration the shared memory of 2Gb as it is a sort of virtual shared memory and is not allocated physically. Is that correct ?

I am trying to burn mac osx 10.5 install disk from from a 6.7gb dmg disk image. I thought I would be using 2 DVD-R 4.7GB discsfor this burn, I was hoping when the first was full it would ask for another to finish the burn. Instead it get the message that the DVD will not hold the choosen DMG. file.
Can I do anything besides buy a dual layer DVD that would hold the whole file?

I want to configure Name Server i.e., DNS to my red hat linux box in a production enviromnt.The ram is 2 GB and Hard Disk size is 200 GB. How much space should I give /var, /usr, /boot, /root and home partition. May be I am wrong in partition point of view while installing fresh red hat but to install for home purpose and server end is different. So kindly guide me the hard disk partition size to ready it for name server.

Is their a command I could use to do this? It needs to be 32MB (33,554,432 bytes), can be either random data or just a blank file, though random data would be preferable, and well... that's it.
Though also, is their a way I could copy the file in a terminal and it print out the info such as average speed and/or total time it took to complete. I'm trying to fight some bad reviews on this flash drive I bought that performs very well, and since stupid comment vs stupid comment doesn't win anything I need to apparently be the first to actually test this drive throughly.
