I have resized the disk in Virtual Box, but this doesn’t show up in the ubuntu VM. As i see here doubts about resize a virtual disk I need to use gparted to use the unallocated space but I do not have enough space on the VM to install gparted. Is there anyway around this? If I do install a gparted iso file and mount it on the cd rom, how do I use it post that?

So, the above disk is LVM partitioned. In order to resize, first we need to check available space in the volume group(allocated/unallocated) vgdisplay #specify volume group name if there are multiple Based on how much free space is there you can add using lvextend, lvextend -L +2G <device_name> So we have extended the file system, now we need to update it using resize2fs <device_name> check your free space again using df, you should be good
