help
|

F2FS is based on Log-structured File System (LFS), which supports
|
|
versatile "flash-friendly" features. The design has been focused on
|
|
addressing the fundamental issues in LFS, which are snowball effect
|
|
of wandering tree and high cleaning overhead.
|
|
|
|
Since flash-based storages show different characteristics according to
|
|
the internal geometry or flash memory management schemes aka FTL, F2FS
|
|
and tools support various parameters not only for configuring on-disk
|
|
layout, but also for selecting allocation and cleaning algorithms.
|
|
|
|
If unsure, say N.

/sys/kernel/debug/f2fs/ contains information about all the partitions

mounted as f2fs. Each file shows the whole f2fs information.

/sys/kernel/debug/f2fs/status includes:
|
|
- major file system information managed by f2fs currently
|
|
- average SIT information about whole segments

- current memory footprint consumed by f2fs.

Extended attributes are name:value pairs associated with inodes by
