Assuming that you've followed the guide you linked exactly, then
/dev/sda7 should be your new free space.
Since Fedora is using LVM, this is going to be easy. You don't actually have to move your
/home filesystem (i.e. the
/dev/mapper/fedora-home logical volume to
/dev/sda7 to extend it: as soon as you add
/dev/sda7 to the
fedora Volume Group, you can extend any of the logical volumes (LVs for short) inside it.
First, boot into your regular Fedora and become root.
(Yes, all the remaining steps can be done in regular Fedora, without GParted Live or similar!)
/dev/sda7 useful for LVM, you'll first need to use
pvcreate on it. This will effectively destroy any existing data on the partition it's aimed at, so be careful.
/dev/sda7 into a new LVM Physical Volume, or PV for short.
The next step is to add it into your
fedora volume group (VG):
vgextend fedora /dev/sda7
At this point, you can use the
vgs commands to confirm that
/dev/sda7 now registers as a LVM PV that is a member of
fedora VG. You'll also see that the VG will have some unallocated space available.
Now, if you really want to move your
/home filesystem to
/dev/sda7, you can do it with the following command:
pvmove -n home /dev/sda6 /dev/sda7
Yes, you can do this while
/home is still mounted and in use!
But if you don't have any strange special requirement that your
/home filesystem must be physically contiguous, you don't have to do that.
As long as you have unallocated space in your VG, you can extend any of the LVs inside that VG. LVM will present the space allocated to the LV as a single logically contiguous unit to the filesystem driver, even if the disk space is physically in separate PVs, or even on separate physical disks. You could just extend your /home LV by whatever amount you wish, up to the amount of unallocated space available within the VG. For example, to extend your
/home filesystem by 32 gigabytes, you need just one more command:
lvextend -r -L +32G /dev/mapper/fedora-home
This operation can also be done on-line, while the
/home filesystem is mounted and in use.
Just remember that while many filesystem can be extended, even on-line, it does not necessarily mean the filesystem can be shrunk as easily. In particular, the XFS filesystem type allows on-line extensions just fine, but shrinking - even off-line shrinking - may not be possible at all. (I think there are fairly recent developments in this area, but not necessarily production quality yet!)
