Adjust the size of default vmdk Vagrantfile disks (you can use this procedure to relocate + resize as well):

1) Shutdown the VM

2) VBoxManage.exe clonehd box-disk001.vmdk E:\Virtualbox_VMs\voracle9x-docker-sa1\voracle9x-docker-sa1-box-disk001.vdi --format VDI

C:\VirtualBox_VMs\voracle9x-docker-sa1_default_1763076112652_13435>"C:\Program Files\Oracle\VirtualBox"\VBoxManage.exe clonehd box-disk001.vmdk E:\Virtualbox_VMs\voracle9x-docker-sa1\voracle9x-docker-sa1-box-disk001.vdi --format VDI 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Clone medium created in format 'VDI'. UUID: f09bc1a5-fdab-44b0-814b-cb599464562f

3) VBoxManage.exe modifyhd E:\Virtualbox_VMs\voracle9x-docker-sa1\voracle9x-docker-sa1-box-disk001.vdi --resize 76800

C:\VirtualBox_VMs\voracle9x-docker-sa1_default_1763076112652_13435>"C:\Program Files\Oracle\VirtualBox"\VBoxManage.exe modifyhd E:\Virtualbox_VMs\voracle9x-docker-sa1\voracle9x-docker-sa1-box-disk001.vdi --resize 76800 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% C:\VirtualBox_VMs\voracle9x-docker-sa1_default_1763076112652_13435>

4) Attach the new disk to VirtualBox media

5) Attach the new vdi disk in place of the existing vmdk (only disk sata0) attached to the VM using VBox.

6) Boot the VM using "vagrant up"

7) Run "fdisk -l" to list the partition table, we will see the partition table changed and new expanded size visible. in my case it expanded from 32GB to 75GB.

8) Run "cfdisk", in my case only 1 disk, so it picked up all the partitions from that disk

9) Choose /dev/sda3 (which corresponds to / FS) and use arrow key select resize, enter new size 74GB in my case; Write, Accept partition modification "yes"

10) Verify all the pvs, lvs, vgdisplay outputs to ensure the current sizes of the / FS is aligned.

11) Run "pvresize /dev/sda3" [partition corresponds to / FS]

12) Run "pvdisplay /dev/sda3" [partition corresponds to / FS] -- should display the extra space in free space.

13) Run "lvextend -l +100%FREE /dev/mapper/vg_main-lv_root" [vg corresponds to the / FS]

14) Run "xfs_growfs /" to accomadate the growth

15) Finally review the size allocated using  df -Th.
