NAME

gzbc - ZBC and ZAC device management graphical interface

SYNOPSIS

gzbc [options] device

DESCRIPTION

gzbc is a graphical user interface allowing to view the state of zones of a ZBC and ZAC device and to execute zone management commands. The zone reset, open, close and finish commands can be applied to zones selected from the list of zones displayed.

The list of zones displayed can be filtered based on zone type and zone condition. Zones are represented graphically using colored boxes indicating zone type and write state.

The device argument must be the pathname to the target device block device file (e.g., /dev/sdb), or to the target device SG node file (e.g., /dev/sg3). On old kernels lacking ZBC and ZAC support, only the device SG node file will be available. The target device may also be a regular block device set to emulate zones with the zbc_set_zones utility.

OPTIONS

Show help options and exit.
Show all help options and exit.
Show GTK+ options and exit.
Use libzbd verbose mode (for debug).
Automatically refresh the zone list every msec milliseconds.
Use size as the unit for displaying a zone position, length and write pointer position instead of the default 512B sector unit.
Specify the X display to use.
