I'm using virtualbox with one of the tests I have for centos 6.4. I realized after creating the disk, the default was too small. I added more disk space with: VBoxManage modifyhd /Users/user/VirtualBox\ VMs/centos\ 6.x/centos\ 6.x.vdi --resize 25000 I then used this site to help me resize the lvm: http://community.spiceworks.com/how_to/show/2768-extending-lvm-partition-with-free-space-from-the-same-hdd-or-with-a-new-partition-from-a-new-hdd-on-centos but when I do: df -h I still see only the original 8gig disk (8gig total - 4gig data/4gig swap)). When I look at pvscan in lvm, it says 23.92GiB is the size of the volume. Why doesn't df see it correctly? Thanks, -wes
