How to Increase or Alter Partition size in Linux without Re-installation of Fresh-installation?
I have 1 TB HDD in which Ubuntu 14.04 was freshly installed keeping partitions as under:
/dev/sda
/dev/sda1 ---> ext4 /boot 3GB
/dev/sda3 ---> ext4 / 35GB
/dev/sda4 ---> swap 12GB
/dev/sda7 ---> ext4 160GB
/dev/sda5 ---> ntfs 419GB
/dev/sda6 ---> ntfs 371GB
During fresh installation as above, the last THREE partitions, ( /dev/sda7, /dev/sda5, and /dev/sda6) being data partitions, were kept untouched and as such. They were not formated. /dev/sda1, and sda3 were ticked to FORMAT and sda4 ofcourse being a swap does not show the the option to format. Thus Ubuntu 14.04 was installed. The HDD having total 1 TB space was split as --> TWO ntfs type (about 790 GB ) partitions are kept for data writing for Windows and Linux. Remaining 210 GB was spared for Linux / Ubuntu Installation. In that 160 GB as Secondary partition for data and remaining 50 GB were spread into for /boot, / and swap as above table.
Over a period of time, for about last couple of months the “/ ” partition shows some warning of lower free space available. (35 GB space shows actually 34.3 GB of which 28.3 as Used and 4.2 GB as Free as per “Properties” in “Computer”)
Now, the OS is upgraded to UBUNTU 15.04 and it may require some more space in “ / “ partition when I add some more softwares or applications etc.
(1)
Can I increase the space of this “ / “ partition without disturbing the OS ?
(2)
How can I alter the space in Linux partitions without disturbing the whole installation ?
Guidance is humbly requested. I have also no thorough knowledge in computer or linux. In other words, I an technically poor, so stepwise detailed guiodance is requested. Please.

Resizing partitions is not an easy task. You have to copy data around, probably even using an external medium for intermediate storage.
Maybe an easier solution to your problem is cleaning up unused data from your partitions.
Please provide the output of the commands
uname -a
lsb_release -crid
df -h
df -i
dpkg -l | grep ' linux-i'
dpkg -l | grep ' linux-h'
apt-get --simulate autoremove
apt-get --simulate autoclean

I am going to provide some explanation to these commands, and also to the output that you gave.
1. uname -a
This command shows the version of the kernel that your system is currently running.
The string "3.19.0-17-generic #17-Ubuntu" shows that you are using the most current version (even not the standard version, but the proposed next one that is currently in test status)
The string "i686" at the end indicates that you are using the 32bit variant of the operating system
2. lsb_release -crid
This command show the release number and name of the operating system, in your case Ubuntu 15.04 vivid.
3. df -h
Shows disk usage, the important lines are those with real disk devices
Filesystem Size Used Avail Use% Mounted on
/dev/sdb3 32G 27G 3.6G 89% /
/dev/sdb1 2.7G 485M 2.1G 19% /boot
/dev/sdb5 391G 215G 176G 56% /media/
/dev/sdb3 (your root file system) is already 89% full.
Total size 32 GB, used 27 GB, usage percentage 89%
4. df -i
similar to previous, but not showing disk size, but number of files on the partitions (which is another constraint)
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sdb3 2138112 867906 1270206 41% /
/dev/sdb1 183264 382 182882 1% /boot
/dev/sdb5 184559672 237347 184322325 1% /media/
Your root file system can hold 2.1 million files, and 400K are used - not critical in the moment. Cleanup actions for disk size will also reduce that amount.
5. dpkg -l | grep ' linux-i'
List all installed kernel packages.
Your output shows that there are 17 versions of the kernel packages installed (they come in pairs), plus remainders of three more (those that do not have ii but rc at the beginning of the line).
Removing gall obsolete versions of these package should free at least 2 GB of space. (more than 100 MB each)
6. dpkg -l | grep ' linux-h'
List all installed kernel header packages
Similar to previous, again 17 version, amounting to about 1 GB disk space (about 60 MB each)
7. apt-get --simulate autoremove
Simulate removal of unneeded packages
Shows 126 packages that seem not to be of any use (no info about space freed by that action)
8. apt-get --simulate autoclean
simulate removal of obsolete packages in the package cache
Shows around 120 MB used in the package cache for packages that are no more current.
+++++++
Summary:
You should clean up obsolete packages. This will free at least 10% disk space on your root file system.
If you need advice how to do this, no not hesitate to ask.

Sir,
Thanks a lot for giving such an informative detail and helping me in understanding the commands and helped me to understand what these command implies. Thanks a lot. I would like to have your advice further for the following TWO matters.
(A)
From above details, I understand that it is advisable to free the space by removing the unwanted and useless packages. For this should I give following commands?
(1) sudo apt-get clean
AND
(2)sudo apt-get autoremove
(B)
Can I use "GParted" a partition editor application to stretch/compress any of the linux partitions? I have some other HDD in my sysem in addition to that bearing Linux(Ubuntu). I usually detach other HDDs while installing the linux or making any basic alteration in the linux. Will this give me safe resultant situation (i.e.using "GParted" partition editor application)?
Thanks in anticipation.

(A)
The two commands
sudo apt-get --purge autoremove
sudo apt-get autoclean
will remove some unneeded packages and delete some unneeded files from the package cache, but this is not everything that should be done. Also several kernel image and kernel header packages should be removed:
What is the output of the simulation command
apt-get --simulate purge ^linux-
(B)
gparted is one of the tools that help reizing partitions.
You have to be aware that you cannot resize a partition that is in use. So you have to boot from another medium, e.g. into an Ubuntu live system from an installation lit, that you can try resizing your hard disk partitions.

O.K., what I understood is
@---> that I can not re-size the partitions of ubuntu from ubuntu ( as I have ubuntu installed on my HDD and wants to resize the partitions of the same HDD on which linux is installed). Am I right?
@---> that I can resize the partitions of ubuntu bearing HDD using Installation CD of ubuntu (I have 14.04 LTS dvd/cd) making this medium First Bootable and proceeding (at the same time I should detach all other HDDs except that with Ubuntu - Is it?)
@---> that alternatively I can do the same thing after booting from another HDD bearing Window-7 and using GParted tool (I think GParted can also be used in windows.
Thank you sir for continuously explaining all the main and peripheral issues of the question.
Thanks a lot.

The simulation of the command looks as expected (removes all kernel packages except the current 3.19.* versions)
So I recommend that you execute the commands
sudo apt-get purge ^linux-
sudo apt-get autoremove
sudo apt-get autoclean
They will clean up obsolete packages.
afterwards re-issue the commands
df -h
df -i
to see the usage percentage of your hard disk after that action.
(B)
it is not strictly required to detach all other hard disks when trying to modify the partitions, but it is a very good idea to do that. It will eliminate the risk of an inadvertent change of the wrong disk.
I never tried using gparted in Windows to access a Unix-formatted hard disk. It might be possible that this is not possible at all.

Many thans for the quick response.
(A)
I will do as per your suggestion and shell let you know result there of. Ofcourse, I shell do this first and let us see how much actual space gets free as a result of this operation.
Then onward I may go for the next alternative (as per B) to see or to learn the effect.
(B)
I would like to have your opinion, if I follow the procedure as under.
In my system, there is a 40 GB HDD installed with Lubuntu 14.04 just as a spare. I today also installed “Gparted” which is found showing all the HDDs along with detail of partitions in each. According to that, the partitions detail of 1TB HDD (having Ubuntu 15.04) is as under:
/dev/sda1 ----------> ext4, Size 2.79GB, Used 594 MB, Unused 2.21 GB, boot
/dev/sda3 ----------> ext4, Size 32.60GB, Used 27.43GB, Unused 5.17 GB
/dev/sda4 ----------> swap Size 11.17GB Used 0.0 B Unused 11.17 GB
/dev/sda2 ----------> extended 885 GB
/dev/sda7 -------> ext4 Size 148.74 GB Used 21.47 GB Unused 127.27 GB
/dev/sda5 –-----> ntfs Size390.63 GB Used 214.90 GB Unused 175.73GB
/dev/sda6 -------> ntfs Size 345.57GB Used 129.56 GB Unused 153.00 GB
Now my actual intension is to keep my Data partitions (sda5 & sda6, both ntfs) UNTOUCHED. Only I want to increase the space in sda3 (ext4), a “/ (root)” partition by compressing sda7 (ext4). May also cause changes in sda1 (ext4) and sda4(swap) to perform this operation. This I want to do for the reason that in future if I install new applications/
While doing this using Gparted, I shell detach all the HDDs except above 1TB and 40GB on which Lubuntu with Gparted tool exists. So from 40GB HDD, changes will be made on 1TB HDD. Will this do well and safe?
YOUR VALUABLE OPINION IS REQUESTED ALONG WITH APPROPRIATE SUGGESTIONS IF ANY
Thanks in anticipation with high regards.

The amount of work required for resizing the partitions very much depends on the sequence of the partitions in your hard disk.
You have to be aware that each partition has to be contiguous. If you want to increase the size of a partition, you have to create free space immediately in front or behind that partition to extend the partition.
This is true for the primary partitions sda1, sda3 and sda4, but also for the extended partition sda2 itself, and again for the partitions inside the extended partition sda5, sda6 and sda7.
If sda7 is the last partition inside sda2, and if sda3 is behind sda2, it might be possible to shrink sda7 and shrink sda2 to get free space between sda2 and sda3 that then can be used to extend sda3.
To see the exact sequence of partitions please provide the output of the terminal command
sudo fdisk -l

This has reference to (A) of #7.
Sir, the results are really very good. As per your recommendations, I applied the following commands in the given sequence.
sudo apt-get purge ^linux-
sudo apt-get autoremove
sudo apt-get autoclean
And the OUTPUTs of "df -h" AND "df -i" BEFORE and AFTER the purging, removing and cleaning of obsolete packages are as under for the comparison:

From GParted user interface (i.e. display window of this partition editor), the sequence (from Left to Right) is as under :
sda1, sda3, sda4, sda7, sda5, and sda6 which is same as that in #8. This seems to be favourable situation as I understand from your above explanation in #9.
Thanks in anticipation.

Reordering the partitions in their real order and adding details:

sda3 and sda7 are not adjacent to each other. Any attempt to use space from sda7 to enlarge sda3 need a lot of moving partitions around.
You could gain 11 GB for sda3 by the following, which requires only a small amount of actions:
shrink sda7 by 11 GB, use the gained space for creating a new swap partition inside the extended partition (probably sda8), delete the current swap partition sda4 and extend sda3 to use the space currently used by sda4.
You have to be aware that there is a high risk of data loss if you mistype a command in gparted, so I recommend doing such action only if you are sure that you need to do it. And I strongly recommend caring for a good and complete backup.

OK, Sir.
Nice analysis you have provided in addition to step-by-step guidance.
Presently I postponed the activity of using GParted tool.
First I shell study the content in the recommended reading as in #9 ---> https:/
So at present, I got my issue mostly resolved and also could obtain the guideline for future.
ONE LAST REQUEST :-
Sir, please give a little brief of the command line meaning or about what it implies, when ever you reply my questions in future on this launchpad.net platform and oblige me.
VERY SINCERE THANKS to YOU - Mr. Manfred Hampl
Best Regards.
