👑 ZBC(8) — zbc_reset_zone 👑

okay so this is the ZBC(8) page from the System Manager's Manual, and we're about to make resetting zones on a ZBC or ZAC device make sense. no cap, it's giving storage-nerd excellence. 💅✨

✨ NAME ✨

zbc_reset_zone — Reset zones of a ZBC or ZAC device. that's the whole assignment, bestie. 🎀

🎀 SYNOPSIS 🎀

zbc_reset_zone [options] device [zone]

💖 DESCRIPTION 💖

zbc_reset_zone is the utility that resets the write pointer position of one zone or all zones of a ZBC or ZAC device. literally its main character moment. 🔥

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 — so don't go looking for the block device file there, okay? 💀

the zone argument specifies the zone to be reset. 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 -lba option is specified, the zone argument is interpreted as the start LBA of the zone to reset. if the -sector option is specified, then the zone argument is interpreted as the start sector (512B unit) of the zone to reset. iykyk. 🦋

💅 OPTIONS 💅

the following options can be specified, bestie:

  • -h, --help — display a usage help message and exit. the "bestie help me" button. 🫶
  • -v — verbose mode (for debugging problems). it's giving "tell me everything" energy. 👀
  • -sector — interpret the zone argument as the start sector (512B unit) of the zone to reset. 512B unit stays exactly 512B unit. 💅
  • -lba — interpret the zone argument as the start LBA of the zone to reset. LBA tea, no substitutions. ⭐
  • -all — ignore the zone argument and reset all zones of the device. all of them. periodt. 🔥
