H A Dzonefs.rst4 ZoneFS - Zone filesystem for Zoned block devices
10 zonefs is a very simple file system exposing each zone of a zoned block device
24 by allowing SSTables to be stored in a zone file similarly to a regular file
26 of the higher level construct "one file is one zone" can help reducing the
34 space that is divided into zones. A zone is a group of consecutive LBAs and all
41 sequentially. Each sequential zone has a write pointer maintained by the
