    Hi all,

    Fedora 17, 64bit
    Ubuntu 12.04 desktop 64bit
    HD 160G

    Ubuntu 12.04 has been installed on the HD first, several days ago, taking up the whole disc without partitioning. Later I added/installed Fedora 17 selecting the "Shrink" option with LVM partitioning and saved the bootloader on /dev/sda1 to make them dualboot. Installation was successful with dualboot option. Unfortunately by mistake I retained insufficient space for Ubuntu 12.04, only about 100M left when it is up.

    Fedora 17 is on LVM partition but NOT Ubuntu 12.04

    Then I took following steps to shrink /home of Fedora 17

    # vgchange -a y

    # resize2fs -f /dev/mapper/vg_fedora17-lv_home

    # e2fsck -f /dev/mapper/vg_fedora17-lv_home
    e2fsck 1.42 (29-Nov-2011)
    Pass 1: Checking inodes, blocks, and sizes
    Pass 2: Checking directory structure
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information
    /dev/mapper/vg_fedora17-lv_home: 477/5070848 files (5.9% non-contiguous), 383520/20258816 blocks
    # resize2fs /dev/mapper/vg_fedora17-lv_home 9G
    resize2fs 1.42 (29-Nov-2011)
    Resizing the filesystem on /dev/mapper/vg_fedora17-lv_home to 2359296 (4k) blocks.
    The filesystem on /dev/mapper/vg_fedora17-lv_home is now 2359296 blocks long.
    # lvreduce -L 10G /dev/vg_fedora17/lv_home
    Do you really want to reduce lv_home? [y/n]: y
    Reducing logical volume lv_home to 10.00 GiB
    Logical volume lv_home successfully resized
    Now about 68G free space is available. But I have no solution to resize / of Ubuntu 12.04 taking up the free space.

    Please help. TIA

    Thanks for your links.

    I tried Gparted before. Unfortunately LVM is NOT supported. Therefore I have to run those steps as posted on my original posting to shrink /dev/mapper/vg_fedora17-lv_home form 78G to 10G. Now about 68G free space is available. Unfortunately Gparted couldn't find the free space.
