Resize2fs doesn't know what partitions are, too. When ran without any extra arguments, it adjusts FS size to use entire device it resides on. What resize2fs does is it adjusts filesystem's size. Extra space will be wasted, though, because you can't store files outside of FS. For all reasonable applications its size should match partition's size, but it can be smaller as well. There's one more layer of abstraction - a filesystem (FS) that resides on a partition.
INCREASE DISK SPACE VIRTUALBOX MAC SERIES
It treats disk as a series of bytes and doesn't even know what partition table is.Īfter resizing the disk, you have to find a tool that understands partition tables and resize appropriate partitions. The command that resizes HD doesn't care about it. Resizing virtual disk doesn't change its contents in any way.Īnd the first layer of abstraction in disk's contents is the partition table. That's why growing the virtual disk doesn't affect file size at all - it just changes a number that indicates disk's size.

disk files don't actually occupy space that isn't occupied on the virtual disk. Resizing virtual disk doesn't necessarily cause the disk file to grow.īy default, virtual disks are sparse, ie. There are a few misconceptions in your train of thought, probably caused by multiple layers of abstraction. With no changes to size (as evident from the use of df) The filesystem is already 498688 (1k) blocks long. Using sudo resize2fs /dev/mapper/vagrant-vg-root If the space is unavailable because the partition needs to be resized, how should I resize it? How should I proceed to actually resize the VM? When I activated and entered the VM via Vagrant, I checked it size using dfĪnd saw that the space available to the VM was not increased. I replaced Box1.vmdk with Box2.vmdk as the storage accessed by the VM using the VirtualBox GUI. However, neither the size of clone.vdi nor Box2.vmdk files was increased to 100GB (that should probably have been my first clue that something was amiss). I used the following commands in order to increase the space available in my virtual machine (Ubuntu): VBoxManage.exe clonehd "c:\users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\Box1.vmdk" "C:\Users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\clone.vdi" -format vdi In continuation to Failure to resize a virtualbox volume
