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
43 to the device. As a result of this write constraint, LBAs in a sequential zone

61 representing zones are grouped by zone type, which are themselves represented
62 by sub-directories. This file structure is built entirely using zone information
