To expand the log storage capacity on the Panorama virtual appliance,
you must add additional logging disks. Expanding the log storage
capacity of an existing logging disk is not supported, and Panorama
does not recognize the additional storage capacity. For example;
if you added a 2TB logging disk, and then expanded that existing
logging disk to 4TB, Panorama continues to recognize the logging
disk as having 2TB of storage capacity and ignores the additional
2TB of storage capacity.
