Using Expanded Disks

Expanding a disk can damage the data or operating system installed on the disk. You may need to apply additional operating system tools or processes before you can use an expanded disk, for example, resizing partitions and filesystems.

After resizing a disk, remember to resize the partitions and filesystems. For example, with the Linux ext3 filesystem, you can execute the following commands when logged into a shell on the VM:

 $ umount /dev/xxx (/dev/xxx is the partition of the resized volume, inside the VM)
 $ parted /dev/xxx
 # resize Y start end (Y is the partition number, and start/end of the partition varies in each case)
 $ resize2fs /dev/sdx
