One morning a couple years ago I started installing a newly released version of Fedora in a virtual machine on my primary workstation.
I always like to run new distributions in a VirtualBox virtual machine for a few days or weeks to ensure that I will not run into any devastating problems when I start installing it on my production machines. You should check the details of the filesystems you intend to use in order to verify whether they can be resized at all and especially whether they can be resized while online.
#VOLUME MANAGER OFFLINE#
The EXT2, 3, and 4 filesystems all allow both offline (unmounted) and online (mounted) resizing when increasing the size of a filesystem, and offline resizing when reducing the size. It is important to note that the filesystem itself must allow resizing for this feature to work. Second, the filesystem itself must be reduced in size before the volume on which it resides can be reduced. The volume manager also allows reducing the amount of disk space allocated to a logical volume, but there are a couple requirements. It provides features like the ability to add disk space to a logical volume and its filesystem while that filesystem is mounted and active and it allows for the collection of multiple physical hard drives and partitions into a single volume group which can then be divided into logical volumes. LVM allows for very flexible disk space management. It turns out that I was wrong, and that logical volume management is very useful. My initial reaction was that I did not need this additional layer of abstraction between me and the hard drives. I have to tell you that, when LVM (Logical Volume Manager) first made its appearance in Fedora Linux, I resisted it rather strongly.
