OpenSUSE :: Empty The /tmp File Or Other File To Free Up Space?
Mar 23, 2010
I've noticed that when I run:
davek@linux-kw2x:~> df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 20641788 8427780 11165368 44% /
udev 961204 192 961012 1% /dev
/dev/sda3 217642344 4037944 202548468 2% /home
davek@linux-kw2x:~>
I have 44% used. It should be much smaller, under 10%. How do I empty the /tmp file or other file to free up space?

In trying to solve a friend's lack of foresight, i have currently disabled my system.
I was using dd_rescue to make a copy of a drive with a corrupt and unfixable Partition Table. I was a fool, and had a drive mounted to /media/Storage, but ran the backup to /media/storage.
Thus, dd_rescue completely filled my primary drive before informing me that there was a problem.
I don't really trust myself with command line work, so I foolishly sudo'ed nautilus and deleted the folder /media/storage.
Unfortunately, I didn't realize it, but the available space on the drive still read 0bytes.
I tried Terminal work to do a sudo apt-get clean command, but for some inane reason, the laptop screen won't support the display setting for the Terminal login, so I just had to hope that I was doing it right.
I wasn't, and decided to try working from a Live CD so I could see what I was doing.
the folder /root/.Trash/ doesn't exist on Ubuntu's install drive, and I can't figure out why the properties of the drive say "contents: 241310 files, 3.7 GB" but also "Total capacity: 52.8 GB. Free space: 0 bytes"
Any suggestions on how I can get this to shake out?

I have decided that my partition table does not meet my needs Barrymore, and I want to shrink the "/" partition by 80GB, and then create another file system on that space. I did some research on-line, and I'm not sure which way is the easiest and more secure way to perform the change with out putting the "/" file system on risk.

I am trying to create an empty file based on the remaining hard disk space. The problem is that when I create a file that is 1 GB large, the df command shows the remaining space to be only 12 kb smaller than it was before the file was created.

I was copying an .avi file to an external hard drive and half way through the copy the drive reset and required remounting. Consequently I have an empty .avi file on the hard drive. I tried to recopy the file and overwrite, but I keep getting 'Could not write to media/harddrive/filename.avi'. I tried to rename to file to be copied but got the same response, I cannot delete the empty file either, as I get an error telling I cannot delete it. I have tried to do this as the user and root with the same result.Any other file I tried to copy onto the external hard drive is fine, just this one zero length file and the file I was trying to copy, the original of the file. I also tried to delete the file on another computer but couldn'tExternal hard drive is a WD elements ntfs, which works great except for this glitch.

I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

I have tried to plan my backup plans. As I want it simple I am gonna use only tar.gz combination of some files that are important. My question then is the following:
-I have a 100GB hard disk with 20Gb free space only. I would like to backup the rest 80Gb to an external hard disk. I run my scripts which end up saving a 75Gb(due to compression) to my external hard disk.
-->Then comes the times to try to see the contents of my archive (just to make sure that I can recover what is inside the 75GB disk file). Do you know if tar.gz needs to decompress the 75Gb file in some /tmp space in my hard disk for showing me the contents inside it? In that case it will not be easy at all to ever look at what is inside it in my hard disk, as there is no 80Gb of free space in my hard disk (20gb only).

I'm starting to push the limit of my /home directory. My machine is Linux/Windows dual-boot. I need to keep Windows as the machine is not "officially" mine, and so might need to go back at some point to a Windows user. All my normal Windows access is via VirtualBox. I have made my Windows partitions as small as possible, and now have an empty D partition as follows:
It's the D* partition that I would like to add to my home directory. Is there an easy way of doing this, or am I looking at a complete re-install of openSUSE?

I have two 250 GB drives setup with hardware RAID 1. I had on sda and sdb: 20 GB swap, 20 GB /, 198 GB /srv all was good until I started to run out of space on 20 GB /. So I booted the server with Suse 11.3 live cd and reduced the size of 20 GB swap to 10 GB and 198 GB /srv to 150 GB on sda and sdb.
All good so far, then tried to increase 20 GB / to 60 GB, but the Partition setup says the Max Size can be 20 GB, I have checked and I have 42.88 GB of Unpartitioned space. I have rescanned, rebooted, Server is still running fine by the way, but the 42.88 GB of free space is not made available for the expansion of 20 GB /.

I have red hat linux server and it has mysql installed whenever i write on terminal command mysql -u root it shows error "ERROR 2002 (HY000): can't connect to local MYSQL server through '/var/lib/mysql/mysql.sock (111) "
And another problem is that it is showing 0 byte free space istaed of freeing the space. it may seems that both problems are dependent on each other.

I have a large file that a process writes to. I would like to empty that file. If I delete it the process will stop writing to it. Just flush the content but keep the file.

I downloaded three iso-images, 1 dvd-image and 2 cd-images:
openSUSE-11.3-DVD-i586.iso
openSUSE-11.3-GNOME-LiveCD-i686.iso
openSUSE-11.3-KDE4-LiveCD-i686.iso
Being paranoid, I created iso-files from the burnt DVD-R and the two burnt CD-R to verify integrity.
The iso-file of the DVD-R was identical to the downloaded image. Both iso-files created from the CD-R were different in size.
The original size of openSUSE-11.3-KDE4-LiveCD-i686.iso is 719.323.136 Bytes.
I only got 718.938.112 Bytes when recreating an ISO-file from my CD-R.
The CD-R is from Sony. When the length of my ISO-file doesn't correspond to the downloaded one, the checksum file verification doesn't work.

I have setup a local repository containing several .rpm files. I created a comps.xml file outlining the category and groups for the local repository. However, when I issue the yum grouplist command, I get the following error:
Failed to add groups file for repository: localRepo - comps file is empty/damaged
However, if I try to install one of the the packages in the repository, it works just fine.
Here are the steps I took to create the repodata:
The comps.xml and repository are stored in the directory:
/var/www/html/myrepo/x86_64
cd /var/www/html/myrepo/x86_64
createrepo -g comps.xml .

I having been searching for a way to create an empty or blank iso file, so that I can mount it, and have a backup application think it's a blank CD. I am tired of wasting CD's by having the application write a recovery CD, just for me to turn around and export it to an iso image to be stored in a online archive, and then throw away the physical CD.

Using awk I pull the first field of a random line from my datafile.myvar1=`awk -F" " 'NR=='$randline' {printf "%s", $1}' myfileThis works fine. The problem is there will be empty lines at the end of the file. Rather than using awkto filter out blank lines I would like to figure this out first.So I test $myvar1 for a blank string after setting $randline to one that I know is blank:test -z "$myvar1" && echo "true" || echo "false"But, this returns "false"? So the string is not zero length. Why? It's a tab-separated file. Is awk storing the tab with the $1 field or something.This is where I get headache. I try to echo my variable to see what it looks like.
echo "$myvar1"
outputs: nothing
echo "My variable is [$myvar1]"
outputs: [y variable is [
Why is the closing bracket at the beginning? What character could be stored in $myvar1 that would do such a thing and how did it get there?

I just installed FC10 and then used yumex to install the vsftpd FTP daemon package. I'm using the vsftpd.conf file that came with the distribution, and its almost identical to one I copied from my FC2 machine's working set-up. When I try to FTP in as a known system user I'm presented with my home directory /home/myusername/. The directory appears empty to the FTP program, but isn't in reality. I can't upload a file to the empty home directory. I can move up the directory hierarchy to /home/, but again that appears as an empty directory.
I don't think it's a vsftpd.conf file issue. I've tried everything I can there. Could it have something to do with permissions? I fiddled with those, but couldn't make an FTP directory listing work.
