== Overview ==
Sometimes you have to resize a VMs disk. This is a fairly trivial process, open the VMs settings, increase the disks size. Go to guest and resize the partition and filesystem, done!<br>
What happens if your VM doesn't see the increase in disk size?

== Ubuntu (and probably other flavors of Linux) ==
As root run the following command to initiate a rescan of the disk.
echo 1 >/sys/class/block/sdb/device/rescan

You can verify the size changes by running:
fdisk -l /dev/sdb

You can also grow the partition by running:
growpart /dev/sdb 1
This will grow the first partition to fill the disk

You can also resize the filesystem by running:
resize2fs /dev/sdb1
