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.
