Here's how I'd do it. Take a backup first! At least a couple of these
commands could result in massive data loss if you have a typo. It's
also pretty important that you be logged in as root, and that no user
whose home directory is under /home is currently logged in.

# Create your target filesystem
mkfs.ext4 $your_new_partition

# Mount your target filesystem
mount -t auto $your_new_partition /mnt/

# Copy your data to your target filesystem.
cp -a /home/* /mnt/

Verify that the data that was in /home now exists in /mnt

# Remove the data from /home/, as it will otherwise continue taking up
space on your hard disk.
rm -rf /home/*

# Unmount your target filesystem,
umount /mnt/

Modify /etc/fstab to mount $your_new_partition at /home

# Mount your new /home
mount /home

You cannot write to /home directly, only in your own /home/me home
directory.

You should probably apply a label to the partition (like "Home") and
then in fstab:

LABEL=Home /home ext4 defaults,exec 0 2

Make sure you moved and not copied your old /home/* stuff. If you
copied, then delete the old /home:

rm -rf /home
mkdir /home

If you really want to write to /home directly as a user, then unmount it
and do:

chmod a+w /home

Now mount it, and do the above command again. Everyone will now be able
to write to /home (and the permission will be kept between
mounts/unmounts/reboots.)

I have formated the new partion with gparted in ext4. Then have mount
the partion mount /dev/sda3 /home/siefke/ext, but with user rights i can
not write to the partion. When i use root then yes. Now i have mounted
the partion in fstab

UUID=9d9e53c3-c3b2-4b96-9958-c79c42e0d20f /home/siefke/ext ext4 defaults 1 1

The same, with user rights can not write.

The root directory of the new filesystem is owned by root.

The only way I know to fix this would be to replace 'defaults' with
'user=siefke' on your fstab line.

could have been so simple... just create partition, mount somewhere, cp -a,
clean /home, mount, fstab:
UUID=BLABLUB /home/ ext4 noatime,discard 0 0

done.
So easy that I can't even remember anything even easier. Maybe putting /tmp on
tmpfs... hm...

As explained in my previous post, you can "chmod a+w" the "ext"
directory when the FS is not mounted, then mount it and "chmod a+w" again.

> UUID=9d9e53c3-c3b2-4b96-9958-c79c42e0d20f /home/siefke/ext ext4 defaults 1 1

You should probably be using "0 2" instead of "1 1". See "man fstab" on
what these do. If you don't know what "filesystem dumping" is, you
don't need to set the first field to 1. The second field is set to 2,
because your root FS should be the only one with fsck priority 1. All
other should be priority 2.

You can just do "chown user: /mount/point" with the filesystem mounted.
The user= mount options only work with non-Linux filesystems.

But /home should be owned and only writeable by root.
