    Resize Hard Drive


    I want to resize my hard drive in gentoo. The problem is im not to sure if that im trying to do is possible. Right now my hardrive looks like this.

    dev/hdc1 /boot
    dev/hdc2 swap
    dev/hdc3 /
    dev/hdc4 /home

    The entire drive is partitioned and there is no free space. I want to resize my /home and give its space to /. Im not really sure how to go about this if it is possible. Can anyone help?

    Yes, you can do that. The simplest way would be to use a LiveCD, as the partitions cannot be mounted while you resize them.

    Try GParted Live CD :

    Re-Size / Re-Partition Hard Drive

    Yes. It is possible to resize or repartition your hard drive.


    Scenario A:

    * If you have adequate space on / to fit the contents of /home, then:
    * this scenario requires the use of gparted (download the bootable cdrom)
    1) Create a new directory under "/" called something like "/home1"
    # mkdir /home1
    2) cp (some would recommend tar or cpio) your files from /home to /home1
    # cp -prv /home/* /home1
    3) un-mount the home partition.
    # umount /home
    4) Change /etc/fstab to reflect the absence of the /home mount
    - no extra spaces or carriage returns in fstab.
    # vi /etc/fstab
    - find the line that has LABEL=/home and whack it.
    - cursor to that line and press the letter "d" twice.
    - press <esc>, then type :wq
    5) verify that all of your home directory information came across.
    6) destroy the old partition.
    # fdisk /dev/hdc
    > d
    > 4
    > w

    7) boot from the gparted live cdrom (it's only around 30MB total to download, accept the defaults at boot.)
    follow the prompts to move the swap, and enlarge/resize the / partition. (you can't move ext2 or ext3, but you can move your swap partition.)
    * all you need to do is enlarge your / partition to consume the space once occupied by /home

    Scenario B:
    Do the above, but you'll need to backup your /home directory to another location first.
    1) do the fstab stuff from step 4 above.
    2) backup your /home data

    example:
    on source computer:
    # tar czv /home | nc 192.168.0.101 9999
    on destination (where you want to backup your information) computer:
    # nc -l -p 9999 > home.tar.gz

    3) run the repartition, dropping /home, expanding /.
    4) restore your data:
    on the restore computer 192.168.0.100:
    # cd /
    # nc -l -p 9999 | tar xvz

    on backup computer 192.168.0.101:
    # nc 192.168.0.100 9999 < home.tar.gz
    <ip addresses are fictional>
    (yes, the destination computer can be Windoze, but you'll need netcat for windows to pull it off. another free download. )

    netcat:

    gparted:
