Expand a Hard Disk with Ubuntu LVM
| # So you're running an Ubuntu server in a virtual machine, and now you need to add 20 GB of disk space to root (/). | |
| # There are quite a few ways to do this, and fortunately you're running the Logical Volume Manager (LVM) in Ubuntu, | |
| # so the process isn't too bad. | |
| # After you make the additional space available in VMWare/Xen/Hyper-V, first reboot your Ubuntu server so it can | |
| # see the new free space (commenter Michal notes that you can avoid this restart by asking the kernel to rescan the | |
| # disk with 'echo 1 > /sys/class/block/sda/device/rescan'). | |
| sudo growpart /dev/sda 3 | |
| pvdisplay | |
