    UBIFS is a new flash file system developed by Nokia engineers with help of the University of Szeged. In a way, UBIFS may be considered as the next generation of the JFFS2 file-system. JFFS2 file system works on top of MTD devices, but UBIFS works on top of UBI volumes and cannot operate on top of …

    UBIFS may be considered as the next generation of the JFFS2 file-system. JFFS2 file system works on top of MTD devices, but UBIFS works on top of UBI volumes and cannot operate on top of MTD devices. In other words, there are 3 subsystems involved: MTD subsystem, which provides uniform interface to access flash chips.

Linux's UBIFS File-System Picks Up Support For Zstd ...

    Jul 14, 2019 · This new UBIFS Zstd compression can be enabled via the UBIFS_FS_ZSTD Kconfig switch for building the UBIFS module with this Zstd support. This Zstd compression support was sent in as part of the UBIFS changes for Linux 5.3. This flash-focused file-system atop UBI has also received support for offline signed file-systems and various fixes.

    Fundamentally, mkfs.ubifs has to know file-system size because UBIFS maintains and stores per-LEB information (like amount of dirty and free space in each LEB) in so-called LPT area on the media. So obviously, the size of this area depends on the total amount of LEBs, i.e. on the volume size.

UBIFS - Wikipedia

    https://en.wikipedia.org/wiki/UBIFS
    UBIFS (UBI File System, more fully Unsorted Block Image File System) is a flash file system for unmanaged flash memory devices. UBIFS works on top of a UBI (unsorted block image) layer, which is itself on top of a memory technology device (MTD) layer. The file system is developed by Nokia engineers with help of the University of Szeged, Hungary.Developer(s): Nokia with help of University of Szeged

    Creating and using a UBIFS filesystem is not as easy as with JFFS2 but UBI/UBIFS is designed to be more robust and UBI will ease the development of new filesystems. The authors of UBI have pointed some memory usage scalability problems but if a second version of UBI were written, filesystems on top of it would not need to be modified.
