ZBC(8)

💖 NAME 💖

This is the ZBC(8) page, bestie. zbc_close_zone — close zones of a ZBC or ZAC device. That’s the whole vibe: zone-closing business, and it’s lowkey iconic. ✨

✨ SYNOPSIS ✨

zbc_close_zone [options] device [zone]

🦋 DESCRIPTION 🦋

Okay so zbc_close_zone is used to close implicitly open or explicitly open zones of a ZBC or ZAC device. No cap, that’s its whole main character job. 💅

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). Pick your pathname, bestie. 🫶

Old-kernel tea ☕: on old kernels lacking ZBC and ZAC support, only the device SG node file will be available.

The zone argument specifies the zone to be closed. This argument is ignored if the -all option is used. By default, the zone argument specifies a zone number, starting from 0 for the first zone of the device. If the option -lba is specified, the zone argument is interpreted as the start LBA of the zone to close. If the option -sector is specified, then the zone argument is interpreted as the start sector (512B unit) of the zone to close. So yes, the same argument can mean different things depending on your flags — read the room, bestie. 🌸

💅 OPTIONS 💅

You can specify these options, and yes, every single one is here:

• -h, --help — displays a usage help message and exits. Helpful icon behavior. 🎀
• -v — verbose mode, for debugging problems. Your “what is going on” bestie. 🔥
• -sector — interprets the zone argument as the start sector (512B unit) of the zone to close. Sector-coded. ✨
• -lba — interprets the zone argument as the start LBA of the zone to close. LBA-coded. 💜
• -all — ignores the zone argument and closes all open zones of the device. All of them. Periodt. 👑
