gzbd-viewer - zoned block devices zone state graphical interface

gzbd-viewer [options] device

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.

Zone type and usage color codes

Magenta Conventional zones
Red Written sectors of a sequential zone
Green Unwritten and usable sectors of a sequential zone
Rosy brown Unusable sectors of a sequential zone

Zone condition color codes

Light blue Explicitly opened zones
Dark blue Implicitly opened zones
Dark orange Closed zones
Grey Offline zones

The device argument must be the pathname of the target zoned block device.

By default, gzbd-viewer will display at most 100 zones using a 10 x 10 grid. This default display size can be changed using options as explained below.
