Log-structured file system for a zoned block memory device

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, configure the processing device to perform operations comprising:

• determining a current position of a write pointer within a memory zone of a zoned block memory device;
• identifying a checkpoint within the memory zone before the current position of the write pointer, the checkpoint comprising an area within the memory zone that is designated for storing write event data of a target file system;
• reading data stored at the checkpoint;
• determining whether the data stored at the checkpoint corresponds to the write event data of the target file system;
• and
• determining a memory address of a root node of a version of a file structure of the target file system based on the write event data.

method comprising:

• writing, by a processing device, file system data to a first area of a memory zone of a zoned block memory device based on a current position of a write pointer within the memory zone, the file system data comprising data files contained within a file system and file structure metadata describing a file structure of the file system;
• detecting, by the processing device, a first write event based on the write pointer advancing past a predefined memory address within the memory zone that corresponds to a checkpoint, the checkpoint comprising a second area within the memory zone that is designated for storing write event data;
• and
• based on detecting the first write event, writing, by the processing device, first write event data to the checkpoint, the first write event data indicating a most recent memory address of a root node of the file structure within the memory zone.
