How to increase the partion devoted to Fedora 19
 

Hello there,

I am new to linux.
I wanted to install fedora on 400GB space of my 500GB harddisk and wanted to have 100GB seperated disk.

But, during the installation process I did some blunder and now I have ended up with Fedora 19 Genome installed on 100B space of my 500 GB hdd with 400GB missing altogether.

What is the easiest possible way to get to the point where I originally headed to ?

Can you show the current layout eg
That's a lowercase L btw

i would boot a live-usb and use gparted to extend/move/delete/copy/play around with you partitions.

[root@localhost /]# fdisk -l

your 100GB partition is /dev/sda2. This holds a LVM group and partition.
Show us the output of and .

you 400GB partition is /dev/sda4.

When we are lucky (since you said it's a new system) you do not have any data on sda4 yet.
What you want to do in this case:
- unmount sda4
- remove sda4 using fdisk
- enlarge sda2 using fdisk
- resize LVM volume group on sda2 using pvresize
- resize LVM partition and file system on sda2 using lvresize

If you already have data on sda4 you start decreasing sda4 and moving it to the end of the HDD using gparted.

Be warned: You need to have a backup of all data. Messing around with partitions and no experience has a great chance to end in a desaster. With experience it still has a great chance to end up in a huge fail.

If you search in the forum here you'll find more details about the single steps. If you have any issues let us know.
