VM reports disk as full, host still has space

[phooijenga]

As far as I understand, there is no way to assign a particular disk size for a Linux VM. I therefore assumed that it would automatically grow as space on the host allows. However, this does not seem to be the case?

$ orb df -h /
Filesystem      Size  Used Avail Use% Mounted on
/dev/vdb1       145G  142G  2.9G  99% /

$ df -h /System/Volumes/Data /Users/paul/OrbStack
Filesystem            Size    Used   Avail Capacity iused ifree %iused  Mounted on
/dev/disk3s5         460Gi   318Gi   122Gi    73%    7.5M  1.3G    1%   /System/Volumes/Data
OrbStack:/OrbStack   145Gi   142Gi   2.9Gi    99%       0     0     -   /Users/paul/OrbStack

$ orb dd if=/dev/zero of=/home/paul/test bs=64k
dd: error writing '/home/paul/test': No space left on device

Is there a way for me to assign more space to the VM?
