I have installed ubuntu 14.04 in windows under vmware workstation 11.

I ran out of diskspace on the VM (I had it set it to 30GB). Within the VM Properties - I have expanded the diskspace to 60GB.

I ran gparted on boot and resized the partition /dev/sda2 (ext) to use the unallocated space. and then resize /dev/sda5 (lvm) to take up the space.

When I rebooted the VM I ran df -h and it not showing the proper diskspace increase. 

Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-root 26G 14G 11G 56% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 2.0G 4.0K 2.0G 1% /dev tmpfs 394M 3.3M 391M 1% /run none 5.0M 0 5.0M 0% /run/lock none 2.0G 0 2.0G 0% /run/shm none 100M 0 100M 0% /run/user /dev/sda1 236M 78M 146M 35% /boot

I have ran lvextend --size +30G /dev/mapper/ubuntu--vg-root - then lvdisplay

 --- Logical volume --- LV Path /dev/ubuntu-vg/root LV Name root VG Name ubuntu-vg LV UUID wCuSu5-h5eH-3Gvy-IB9N-F1CE-Vrv7-jD6jHm LV Write Access read/write LV Creation host, time ubuntu, 2015-06-16 11:09:09 -0400 LV Status available # open 1 LV Size 55.76 GiB Current LE 14274 Segments 2 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:0

I have rebooted. Still no volume change. I'm lost.

    Did you resize2fs /dev/ubuntu-vg/root after you extended the LV? Commented Sep 15, 2015 at 23:34

Reset to default

The step you've missed is that after you've resized the Logical Volume, you need to then resize the filesystem that is in that LV. For ext[234] filesystems, you can do this "online" (with the filesystem mounted) by running

ext2resize /dev/ubuntu-vg/root

If the LV is formatted with another filesystem, check its documentation for the correct way to resize it.
