Description
gzbd-viewer is used to dynamically display the state of zones of a zoned block device. Each zone is
displayed as a box representing the sector range of the zone. A zone box is filled with different colors
based on the zone type and on the use of sectors within the zone. The condition of zones is indicated by
highlighting a zone box border with different colors.
