VFS for Git is designed to ease the handling of enterprise-scale Git repositories, such as the Microsoft Windows operating system (whose development switched to Git under Microsoft's internal "One Engineering System" initiative). The system exposes a virtual file system that only downloads files to local storage as they are needed.
A cause of confusion is the fact that the file system abstraction used by the Linux kernel is also called the virtual file system (VFS) layer. This is however at a lower level. The GVfs model differs from e.g. GnomeVFS, which it replaces, in that file systems must be mounted before they are used.
A single-file virtual file system may include all the basic features expected of any file system (virtual or otherwise), but access to the internal structure of these file systems is often limited to programs specifically written to make use of the single-file virtual file system (instead of implementation through a driver allowing universal ...
In recent Linux kernels, the xfs_freeze functionality is implemented in the VFS layer, and is executed automatically when the Volume Manager's snapshot functionality is invoked. This was once a valuable advantage as the ext3 file system could not be suspended [ 26 ] and the volume manager was unable to create a consistent "hot" snapshot to back ...
Microsoft developed the Virtual File System for Git (VFS for Git; formerly Git Virtual File System or GVFS) extension to handle the size of the Windows source-code tree as part of their 2017 migration from Perforce. VFS for Git allows cloned repositories to use placeholders whose contents are downloaded only once a file is accessed. [110]
Lustre is an open-source high-performance distributed parallel file system for Linux, used on many of the largest computers in the world. Parallel Virtual File System (PVFS, PVFS2, OrangeFS). Developed to store virtual system images, with a focus on non-shared writing optimizations. Available for Linux under GPL.
FUSE was merged into the mainstream Linux kernel tree in kernel version 2.6.14. [8] The userspace side of FUSE, the libfuse library, generally followed the pace of Linux kernel development while maintaining "best effort" compatibility with BSD descendants. This is possible because the kernel FUSE reports its own "feature levels", or versions.
A cause of confusion is the fact that the file system abstraction used by the Linux kernel is also called the virtual file system (VFS) layer. This is however at a lower level. Due to perceived shortcomings of GnomeVFS [1] a replacement called GVfs was developed. GVfs is based on GIO and allows partitions to be mounted through FUSE. [2]
