General :: Using An Empty Ex4 Partition
Apr 12, 2011
I have Ubuntu in one partition . The partition is about to be full..I have a spare partition which I thought could merge with the existing..But I guess it is not possible. I am slightly confused with the way linux stores the files. There is a root directory and within that there are boot ,Var,tmp and home..
Suppose I install an application from a package manager , I really do not understand where the path is ...Supose I want to store certain new applications in the spare partition , how do I tell the system? Also while installing it doesnt give a choice regarding the path ...All I see is a couple of files exracted and when it completes , it sits on the menu neatly. From a storage perspective how do you gain control? Say in Win , normally any package will ask for the path which you can customize..How do you plan the storage of files in Linux?

The partition is formatted to ext3, starting with block 1 on the drive. The mount point for /dev/sdc1 lists 0 files when doing `ls -A` `df -h` shows that the partition has 92MB used. How is this space being used, and how can I free it up?edit: I guess this isn't a newbie question.

I have a broken DVD drive and no others available right now to burn a DVD iso to so I'd like to use a empty hard disk instead.
I've tried Unetbootin but that only copies a few megabytes of files - the rest of the image data in the ISO is ignored.
I have verified the ISO is valid and working with VirtualBox. It's MD5 hash is also as expected. But I need to boot at the real bios not an emulated one.
I've also tried things like:
sudo cat /disk/image.iso > /dev/sdb1
and that got "Permission denied" -

On a certain computer, I had four primary partitions. The person who installed the Windows 7 on the computer made two partitions for the Windows (sda1 and sda2). Then I made another two primary partitions (sda3 and sda4). sda3 was empty. sda4 is an extended partition that contained the /swap, and /.According to someone else, some viruses get in on the Windows partitions and can then get over to the Linux partitions if they are primary and right after the Windows partitions, or something like that. This person suggested that I create sda3 when I install Linux(SLES 10), but to install Linux on sda4. Then later I can change sda3 to secondary.So I tried this, and the Linux installation went fine.
I decided to change sda3 before I load the application software onto the computer.So I put the GParted CD in, but to my surprise I realised that the harddisk was actually 1 TB, and not 500 GB as I thought. So I had extra space to the right of sda4. I wasn't quite sure what to do with sda3. I thought that perhaps it would be better to unallocate sda3, move the current sda4 to the left, and then make another primary partition on the right of sda4, or just stretch sda4 both ways.Anycase, I unallocated sda3, and just left sda4 as it was.Hm, perhaps you can anticipate the end of the story. I removed the GParted CD, and restarted the computer, but now the computer doesn't let me choose whether I want to boot into Linux or Windows. Um, it doesn't boot at all from the harddisk.
I know it's dangerous to play with partitions, but sometimes the job won't be done if you are too afraid of doing anything, and I dare say you won't learn anything either. There was nothing on sda3, so I didn't think it would have nasty after effects. There isn't any important data on this computer yet, it was two new installations of Windows and Linux. So I guess I could format the harddisk and just reinstall everything, but I would like to learn what goes on underneath the surface.

How would I combine a empty partition with my existing partition? A reinstall is just an option and I need more disk space

So the other day I got myself a nifty ThinkPad x100e. I immediately removed windows 7 started, and installed UNR 10.04.It has a 250GB hard drive, which I decided to partition, so that I can keep all my stuff on the new partition, and then a fresh format or install of the OS would be easier.After struggling to take ownership of my own damn partition after creating it and mounting it, I discovered a rather interesting problem. I KNOW the partition is empty, but when I right click and go to properties, it says that 10GB is already used? This is rather confusing to me

I have Win7. I partitioned my C: and made a empty F:(97gb). I want to install 11.2 on F:.
1) At Sys Ananysis I get; The partitioning on disk /dev/sda is not readable by partitioning tool parted... You can use the partitions on disk /dev/sda/ as they are. You can format and asign mount points on them. But you can not add, edit, resize, or removefrom that disk with this tool. I click OK
2) New Installation, Use Auto Config
3) Time Zone
4) KDE (same results with Gnome)
5) Partition Based. I go to Create Partition Setup.
6) In CPS I get

I gave upon 11.3 M4.Tried installation by text mode but there's another screen showing various USB devices status superimposing on the Linux text install. Returned to Live installation via Live CD. Installation completed > restart >autoconfig failed. Tried live installation again but Suse kept suggesting installing into one of the empty 2 Gb partitions. Also had problems with Gparted Live 0.5.1-1 CD because somehow the keys froze. Had to replace it with 0.5.2-1. I am installing 11.2 on a laptop but right now I am stuck with frozen "Creating cache files for fontconfig". This has taken over an hour and nothing seems to be happening. I have successfully installed openSUSE 11.2 on an older laptop and a desktop. Also experienced installing Windows 7, Ubuntu and PC-BSD on both types of machines.

I have a server running Fedora 6, which I wish to upgrade to Centos 5.4. This will be a lengthy switch over because of all of the apps I need to convert etc. As a precaution, I would like to keep my old Fedora running as multiboot. I have a boot partition, a fedora partition (root), and an empty partition for Centos.
Can I run the Centos installer and direct it to install onto the empty partition (I don't care if it formats it)BUT only add to the boot partition (not reformat it).? I don't want to lose the kernels/images on the boot partition, and from what I've seen most installers wipe out the boot partition prior to adding their own files.

The swap partition says that it is empty. When I installed Slackware I'm sure that I pointed to the right place for the swap. Or does it not show any size because none of it is being used?

Just ran into a problem involving mdadm, a disk which had been in a raid array, and an attempt to reformat. Basically, I went to reformat some partitions which had been in raid, and one of them threw the error andy@andy-desktop:~$ sudo mkfs.ext3 /dev/sdb5 mke2fs 1.41.11 (14-Mar-2010) /dev/sdb5 is apparently in use by the system; will not make a filesystem here! An attempt to umount revealed it was not mounted. lvdisplay and fuser did not reveal anything to me, so I just started looking around. I was graphically navigating /dev and noticed a /dev/md_d0 which did not look like /dev/md_d1 etc (it was missing a little arrow). I had not seen this notation before (my raid was md0), but figured it couldn't hurt to try stopping it.
andy@andy-desktop:~$ sudo mdadm --detail /dev/md_d0
mdadm: md device /dev/md_d0 does not appear to be active.
andy@andy-desktop:~$ sudo mdadm --stop /dev/md_d0
mdadm: stopped /dev/md_d0
After this, the partition formatted fine! I saw a lot of instructions including zeroing the partition and removing a logical volume, but the above was the only thing which worked for me! Just posted it in case it helps someone else. I know I've not been terribly technical!

Currently I have ubuntu 10.04 LTS as the only OS.I have two partitions one for ubuntu and it is ext by default for ubuntu's files.The other is empty NTFS. (yes, it is formatted in NTFS but I haven't saved anything yet on it).The problem is: I want to install win xp sp3 on this empty ntfs partition safely (without losing ubuntu).My friend told me ubuntu will be lost even if I didn't touch its own partition.

When I load the disk I can view my backup drive properly but when I try to view my working drive it shows it as being empty. I also noticed that I had a 1 mg unallocated partition at the beginning followed by my ubuntu partition.
I then ran gparted in terminal and it did show the partition as having my system on it but I am not able to perform any tasks. No moving or resizing.

I have a 120GB HDD with a 22GB partition for Ubuntu and the rest for Windows XP. Windows finally died on me so I attempted a fresh install on its partition. However, the install threw a ton of errors so I used a LiveCD to re-install Grub and I booted into Ubuntu. I open up the disk utility to re-format the Windows partition so I can re-try re-installing Windows, but immediately I notice that the partitions are not right. If you add up all the partitions, they are about, say, 18 million terabytes over my HDD's 120GB capacity. Ahhh! What do I do?
I don't think anything is terribly altered, since I can still boot into Ubuntu, but I am completely confused and slightly worried that I might kill any chances to save my HDD I can't post a screenshot due to my post count, so the image loses some of its efficacy in making it small enough for an attachment. Here is the output of fdisk -l: Code: omitting empty partition (5)

NOTE: I also searched for the palimpset error and I found a Bug Report there: [URL. I don't know if these informations could help to fix this problem, I think it's related and probably cause by the installation of Windows XP and the way that gparted and palimpset read the partitions.

I looked through google but can't find an answer for this..... say I have a directory called "files"; this directory contains several other directories..... what I wanna do is delete ALL the files within the subdirectories, but NOT delete the subdirectory. Can this be done easily without having to run a command for each subdirectory?

Lucid 10.04 distro. On an ext usb hd I have 250วด info in 6 directories. All directories are visible in terminal mode mod 755. All directories are visible in nautilus, all files are visible except in one directories which contains 200gig of videos.A file search shows all in all directories. All files can be opened mv, cp etc. I can move a file from this directory to another and all is well.In my Debian 5.05 distro with the same hd and directories etc, this problem does not occur.

I just had a bad experience with a server, and now i have a 17GB lost+found. It appears a lot of the stuff in there are folders which are empty. Since those really serve no purpose as far as recovering data from what I can tell, is there a slick way to delete just the empty folders from my /data/lost+found folder, leaving me with just the stuff I truly need to look through?

OS: DebianMail Server : PostFixAV: ClamAVI have a newly created SMTP mail server and so far, everything is going great. Over 300 mails are being sent a day and no major issue has come up since then.However, the thing is that every morning I'm rotating my logs so that mail.log becomes mail.log.0 and so on.Its working fine but this morning, mail.log after having been empty and rotated, is empty and nothing is being logged anymore in it.The strange thing is that mail.info is but not mail.log. Mail server is still working well, syslog shows nothing strange, mail.err either, everything is working smoothly as its always been since I started everything, but my mail.log is being kept empty

I'm trying to use tar to tar files before transfer, so I can keep the entire file path rather than losing it along the way. However, when I try to tar an empty folder, it tells me that it is cowardly refusing to create an empty archive. I want to keep the empty folder on the other end, but don't want to put anything else into the archive to make it non-empty. Is there any way to do this?

I am looking for a way to delete the currently entered commandline without wasting seconds on the "Backspace"-key.
For example I scrolled the bash history and have a long commandline that would execute when I pressed ENTER:
~$ aptitude search openssl | grep dev
But now I decide that I do not want to execute this command. Can I get an empty prompt fast without deleting the whole line with Backspace? On the Windows "cmd" you can just press ESCAPE and it is gone. This behavior would be what I want.
The question may seem trivial but this is bothering me for a long time now.

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.

I have a bunch of NTFS externals set up as samba shares on Linux Mint and they'll work just perfectly, but after a while they will stop functioning and the folders will be empty. It fixes itself if I restart my computer but only for a little while. This happens whether i access them locally or over the network through samba. I don't want to set the as ext3/4 because I need to access on windows from time to time (i'm dual booting) and I don't want to set them as fat32 because they I have files over the filesize limit on there.
