Hi guys!

As you probably can notice, I am not using Win8 as much as F20. So, I want to extend my /home/ partition and reduce space on the C:\ partition. However, I am not aware of how to do that without destroying the C:\ partition as a whole. Any advice or tips? Also, it would help not to use a LiveCD or USB.

To use your discontiguous partitions /dev/sdaN and /dev/sda13 to back a single filesystem, do:

(resizing the ntfs partition and creating a new one in the empty space is left as an exercise for the reader)

systemctl isolate multi-user.target #get out of graphical mode so you aren't using /home - log in as root

rsync -vrpPX /home/ /path/to/ext4_usb_backup/ #copies files, preserves permissions

umount /home #we are destroying the data here

pvcreate /dev/sdaN #format for lvm use

pvcreate /dev/sda13 #format for lvm use

vgcreate hello_vg /dev/sdaN /dev/sda13 #create volume group

lvcreate hello_vg/hello-home --size 500G #create logical volume

mkfs.ext4 /dev/hello_vg/hello-home #create a filesystem

mount /dev/hello_vg/hello-home /home #mount the filesystem

rsync -vrpP /path/to/ext4_usb_backup/ /home/ #restore backup

blkid /dev/hello_vg/hello-home #Get the filesystem uuid

nano /etc/fstab #put your new UUID in for the /home mountpoint

systemctl isolate graphical.target #resume your clicky operations (adding

@randomuser - I have traditional partitioning; is that a problem? Also, do I have to use LVM, and will this mess up the system (change the start sector of /boot/efi)? Last, will both partitions be mounted at /home? All this looks a little risky to me. Sorry for taking so much of your time :(

I'd add -X to that rsync command to preserve extended attributes (should keep selinux security contexts). The rsync command that anaconda uses to install Fedora is 'rsync -pogAXtlHrDx', or just use what anaconda uses.

My installation logs don't show anaconda using rsync, but good call on -X. Updated.

@hello - for your questions: I don't understand the concern about 'traditional partitioning'. I can tell you aren't already using LVM, that's why I gave you the instructions.

Yes, you have to use LVM to take advantage of LVM's features.

No, there are no steps listed that change the start of the EFI partition. You'll need to change the end of /dev/sda5 but I didn't cover that.

No, both partitions aren't mounted at /home. The logical volume is mounted at /home, and the partitions supply blocks for the logical volume.

@randomuser - Sorry for wasting your time, but will the total space of /home be 500GB?

I assume here that the C:\ partition is /dev/sda5 , because of the size (450.7G) . If you want to decrease the size of this partition, you can do it easily with gparted. Install gparted , it's an easy to use and powerful GUI tool for managing partitions/disks..etc.

But

as you said you want to increase the size of Fedora's /home/ (your /home) partition, you must use a Live media in order to do this. You cannot manipulate mounted partitions and when you are logged into Fedora the /home/ partition is mounted. So, you have to use a Live media (CD/DVD/USB) boot from there, and the /home partition will be unmounted, thus you can manipulate it with gparted.

Gparted is not included at live media, so install it there as well.

Pay attention now

Gparted has a feature where it can preview all the operations before you actually apply them. This is very handy and you can see what you will do, before actually do it.

  • Resize /dev/sda5
  • Delete the partition that will result from the resizing and leave it unallocated
  • See if you can merge this unallocated space, means to expand the /dev/sda13 partition, which is your /home
  • If and only if you can do all these actions without problems, then hit the apply button

@NikTh- Thanks for the answer, but would help if you give step by step insructions how to move the unallocated space next to /home without changing the start sector of /boot/efi.

@NikTh - help?!?

@hello, please upload a picture from gparted. Thanks.

@NikTh Done, thanks for the help so far BTW. Also, that pic is NOT from a live CD. Couldn't get my hands on one.

abadrinath gravatar imageabadrinath ( 2014-07-15 03:41:59 -0500 )edit

Yes, but you should use a Live media, or else you will not be able to expand the /home partition. What you have to do, is to drag every partition next to unallocated space (from right to left) until you reach the /home partition (/dev/sda13) and then right click and resize/move again, but this time expand(resize) the partition (drag it with the mouse cursor). The unallocated space should be under the /dev/sda13 in order to expand /dev/sda13/ properly.
